Wired Ethernet support?

[dreamy1]

not an issue :-)

Hello,

is it planned to add wired ethernet support for this great work?

Actually, there are some modified variants of your software with support for e.g. LAN8720. The only difference for the software part is that the SPI bus for the lcd and sd card has to be moved to the second hardware SPI bus (called HSPI) because the RMII pins are needed for the LAN chip. In consequence, some pins have to be switched but this should not be a problem because of the GPIO definition in the NVS text file.

An ethernet connection is for most users with an automation systems the best choice. The RMII interface of the ESP32 supports wired ethernet out-of-the-box.

Here is an example schematic showing the new pin definitions - VS1053, Ethernet via RMII and LCD are possible at the same time:

[Edzelf]

I guess the radio will work well on a WT32-ETH-01 board. The Ethernet interface will use som GPIO pins, so maybe some features must be eliminated.

[dreamy1]

Hi Ed,

it would be great if there would be a possibility in your code to switch to HSPI pins for the SPI bus. Only renaming the pins does not work because the standard SPI bus is VSPI and i am not good enough in software to get that solved (as what i learned, a new SPI class has to be defined for VSPI).

With this modification there would be a maximum flexibility for other hardware parts. It would be great if you have a look on it.

Thanks, Stefan

i guess you could use any vspi or hspi pin by just changing the pin in config. if that is not working then you can just create adruino SPIClass SPI2(pin, pin, pin, speed) and replace the existing SPI to SPI2 you just created before the SPI begin function.

is very simple 2 line of codes. give it a try.

[tsctrl]

hi @dreamy1, can you point or share the url for the other variant or fork of the internet radio that was using the lan module?

[dreamy1]

Hi @tsctrl,

the radio with LAN is here: https://sites.google.com/site/pcusbprojects/5-custom-projects/er-secure-esp32-internet-radio-with-wired-ethernet-connection

It is a modified version of the V1 of the radio from Ed. There is also a modification for using HSPI, but this doesn't compile (it seems that the SPI.h of the ESP32 was changed in the meantime by Arduino IDE). I tried to get it work with some code you posted above (new SPI Class), but with no success.

Regards, Stefan

[dreamy1]

Did you have a look on it @tsctrl ?

[tsctrl]

just dont use the arduino ide. use at least platform io. i doubt you couldnt change the spi pin. SPI class is predefined in the lib and you should able to use the VSPI pin with that predefine SPI class. in fact i just use VSPI pin using the SPI class and codes that was created by Ed and it works.

if that was not work either. the worst case is you have to modify the esp32 arduino library. but i dont think you have to do this.

[tsctrl]

here is the example you can follow: https://github.com/espressif/arduino-esp32/blob/master/libraries/SPI/examples/SPI_Multiple_Buses/SPI_Multiple_Buses.ino

[dreamy1]

Thanks for the input - i tried that already but it seems that there is a bit more than a declaration at the entry of the code because the whole spi commands must contain a "hspi" and the whole declaration of the VS1053 is based on VSPI.

And i am worse at software...but good in hardware :-)

[dreamy1]

Here https://github.com/schreibfaul1/ESP32-vs1053_ext/blob/master/src/vs1053_ext.cpp#L146 a simple solution seems to be implemented without any change on the ESP32 SPI library. It works out of the box with my hardware.

But i am not able to adapt it to this version of the radio. So any help is really appreciated :-)

[tsctrl]

you need to have this declaration and have all your code to use this SPI Class to handle the SPI bus data transfer instead of Predefined SPI Class. And you have to point the initialization to that Class.

https://github.com/schreibfaul1/ESP32-vs1053_ext/blob/0014147924b574987d11e730cfa50d315d9edf73/src/vs1053_ext.h#L153

for Ed implementation is more simpler and use the SPI Class declared in the library that use VSPI by default. https://github.com/espressif/arduino-esp32/blob/6cfe4613e4b4846e1ab08c7f78b7ea241f52c7da/libraries/SPI/src/SPI.h#L56

so, to change is by:

1. create new SPIClass spi2 with HSPI/VSPI.
2. change all SPI text to spi2. such as SPI.beginTransfer to spi2.beginTransfer

basically if you use the same code you share it should work.

[dreamy1]

Thanks, i tried exactly what you suggested. But i got a lot of errors while compiling, all related to SPI. Maybe the place of the declaration was wrong and it seems that there are other dependencies to https://github.com/Edzelf/ESP32Radio-V2/blob/main/lib/codecs/src/VS1053.cpp

[Edzelf]

Next week I hope to get a WT32-ETH-01 board. And I will see if I an run the radio software on it.

[dreamy1]

Thanks a lot Ed, that would be great to get it to work!

Stefan

[dreamy1]

Hi Ed,

did you get your WT32-ETH-01 board?

Regards, Stefan

[Edzelf]

Yes, just one hour ago.

[dreamy1]

Great :-)

If you need any help regarding the hardware, please let me know. The WT32-S1 seems to be a low-cost variant of the common ESP32...i can't find any info about RAM and if it is a dual core cpu.

Maybe here are some useful info about the WT32-ETH01: https://github.com/khoih-prog/WebServer_WT32_ETH01

[Edzelf]

WT32-ETH01 is supported now, define ETHERNET in config.h. Pin usage for Ethernet controller WT32-ETH01:

     "pin_eth_mdc"      23
     "pin_eth_mdio"     18
     "pin_eth_power"    16
     "????"             00

[dreamy1]

Boah....Ed, you're absolutely great! I am really very impressed that you are able to present a solution so quick :-)

I will try it - just two questions: 1) Is it possible to not use "pin_eth_power"? This is because in my application the activation of the LAN8720 is controlled externally. 2) Does SPI now still use hardware HSPI? Or is this still VSPI with routed signals by the GPIOMUX of the ESP32?

BTW: please let me know how i can estimade and support your great work by a paypal donation or you can get one of my hardware solution for this radio for free...i will take some pictures when it is running final :-)

[Edzelf]

Yes, you may set the 3 pin definitions in the config page of the webinterface, or change the defaults in the source of main.cpp. The software is still using the same SPI bus. I did not test it yet, just connected a I2S module to a bare WT32-ETH01. Surely I'm interested in your hardware solution.

[dreamy1]

Just battling with compilation errors...i added the lib ESPAsyncWebServer from here: https://github.com/me-no-dev/ESPAsyncWebServer

But it seems to be not the correct one:

C:\Users\Stefan\Documents\Arduino\libraries\ESPAsyncWebServer-master\src/ESPAsyncWebServer.h:33:10: fatal error: AsyncTCP.h: No such file or directory

include

      ^~~~~~~~~~~~

compilation terminated.

[dreamy1]

Problem solved, it was the AsyncTCP-master library missing.

Unfortunately, a lot of new compilation errors comes with ST7789 defined in config.h, e.g.:

C:\Users\Stefan\Desktop\ESP Radio\ESP32_Edzelf\ESP32Radio\ESP32Radio.ino: In function 'void tftset(uint16_t, const char*)': ESP32Radio:848: error: 'TFTSECS' was not declared in this scope if ( inx < TFTSECS ) // Segment available on display ^~~ ESP32Radio:852: error: 'tftdata' was not declared in this scope tftdata[inx].str = String ( str ) ; // Yes, set string

...and much more regarding the tft declarations.

[Edzelf]

Show your config.h. You probably have no display configured.

[dreamy1]

[Edzelf]

Define ETHERNET, not ETHENET.

[dreamy1]

Already corrected, the compilation errors are the same - all with the TFT functions.

[dreamy1]

This is my workspace:

[Edzelf]

Complicated, because it is different than in the Github repositry: And what do you mean by installing Adafruit libraries? All librararies are installed by teh platformio.ini file.

[dreamy1]

I don't use platformio, i still use the regular arduino IDE since years now. I checked every single library needed, they are all installed correctly.

I just tried to switch to an ILI9341, but the compilation errors are the same. It has something to do with the use of the graphic libs.

[Edzelf]

Yes, I see now. Be sure to use one of my display libraries. There 'TFTSECS' is defined in the header file of the configured display.

[dreamy1]

Yes, of course i use your ST7789 lib. It seems that this lib is not included correctly from the main sketch. I copied all the original files from your .zip and placed them as mentioned in your documentation. So this should all be correct.

[dreamy1]

All .h and .cpp seems to be loaded correctly:

[tsctrl]

hi @dreamy1,

i have question for you custom hardware design, do you have oscillator en pin for LAN8720 connected to esp32 gpio pin? i did not see you pin setup on the config file

thanks!

[dreamy1]

I handle that with a GPIO pin of the VS1053.

[Edzelf]

I have updated the procedure for compiling with the Arduino IDE in the document. There is also a change in main.cpp that effects the position of the config.h file. I tested the procedure and it compiles without problems.

[dreamy1]

Thank you very much Ed!

I still got a lot of errors while compiling and it seems most are related to some "#" in my config.h. After removing them, only the following errors occure:

I will. Are you aware of the second half of this file? Only "#define" lines are expected. The rest should be in the NVS, by using the config page of the web interface.

[Edzelf]

Compilation is okay. Please check line 92 of the main program. It should read: #include "config.h" // Specify display type, decoder type

[dreamy1]

Oha :-) Now it compiles without any errors. Big sorry, that was my mistake with misunderstanding config.h and the config page in NVS :-(

Thank you for your great help!

So my last question for today: Without a specific pin definition for various signals before uploading the code into the hardware i expect that my hardware will not start correctly. I think this will apply to other hardware too because the VS1053 can't start without defining the corresponding pins before.

For example, the following pin definitions are "fixed" in my hardware: pin_spi_sck = 14 pin_spi_miso = 12 pin_spi_mosi = 13 pin_ir = 39 pin_tft_bl = 2 pin_tft_cs = 4 pin_tft_dc = 5 pin_vs_cs = 15 pin_vs_dcs = 32 pin_vs_dreq = 33

I think the best solution in my case would be to change the lines 1863ff - so instead of "-1" i would place the pin used in my hardware:

**struct iosetting klist[] = { // List of I/O related keys { "pin_ir", &ini_block.ir_pin, -1 }, { "pin_enc_clk", &ini_block.enc_clk_pin, -1 }, // Rotary encoder CLK { "pin_enc_dt", &ini_block.enc_dt_pin, -1 }, // Rotary encoder DT { "pin_enc_up", &ini_block.enc_up_pin, -1 }, // ZIPPY B5 side switch up { "pin_enc_dwn", &ini_block.enc_dwn_pin, -1 }, // ZIPPY B5 side switch down { "pin_enc_sw", &ini_block.enc_sw_pin, -1 }, { "pin_tft_cs", &ini_block.tft_cs_pin, -1 }, // Display SPI version { "pin_tft_dc", &ini_block.tft_dc_pin, -1 }, // Display SPI version { "pin_tft_scl", &ini_block.tft_scl_pin, -1 }, // Display I2C version { "pin_tft_sda", &ini_block.tft_sda_pin, -1 }, // Display I2C version { "pin_tft_bl", &ini_block.tft_bl_pin, -1 }, // Display backlight { "pin_tft_blx", &ini_block.tft_blx_pin, -1 }, // Display backlight (inversed logic) { "pin_sd_cs", &ini_block.sd_cs_pin, -1 }, // SD card select { "pin_vs_cs", &ini_block.vs_cs_pin, -1 }, // VS1053 pins { "pin_vs_dcs", &ini_block.vs_dcs_pin, -1 }, { "pin_vs_dreq", &ini_block.vs_dreq_pin, -1 }, { "pin_shutdown", &ini_block.shutdown_pin, -1 }, // Amplifier shut-down pin { "pin_shutdownx", &ini_block.shutdownx_pin, -1 }, // Amplifier shut-down pin (inversed logic) { "pin_i2s_bck", &ini_block.i2s_bck_pin, -1 }, // I2S interface pins { "pin_i2s_lck", &ini_block.i2s_lck_pin, -1 }, { "pin_i2s_din", &ini_block.i2s_din_pin, -1 },

ifdef ETHERNET

{ "pin_spi_miso",  &ini_block.spi_miso_pin,     19 },
{ "pin_spi_mosi",  &ini_block.spi_mosi_pin,     23 },** 

Would that be correct?

[Edzelf]

I guess it's best in this case to change the defaults in the source code, at least for the ethernet pins. As soon as you have the webinterface running, you can set the ethernet- and other pins in the config page of the webinterface. Then the defaults have no effect anymore.

[dreamy1]

So the place above in the main.cpp would be right or is there another position what has to be changed?

I think for optional hardware it would be suffcient to define that later by the webinterface, but in my case TFT, VS1053 und Ethernet is always fixed. And these pins should have defined signal levels before the first starting of the software.

How is the software reacting at the moment if e.g. VS1053 is not found by the SPI bus because the pins are not defined correctly before updating them via the webinterface? Maybe that would be a general improvement defining that in the main.cpp?

[Edzelf]

The idea is to have as little as possible pin definitions in the source code. If you do not have WiFi, it will be very difficult to "bootstrap" the device. You may however use the sketch in the tools directory to fill the NVS at forehand. Once the NVS it set, the drivers for mp3 decoding, display, rotary encoder, touch and IR will read the pin settings from NVS. You can play around with the NVS settings without changing the software.

[dreamy1]

I understand that there is a big benefit for flexible hardware options regarding the software updates. So you can provide universal updates of the main software and the hardware definitions are then read by the NVS.

On the other side, every hardware always starts with an empty ESP32 and empty NVS - for those who compile the code on their own, it would be an alternative way to get the known pins of the hardware used defined before compiling and uploading...and then you have a working radio at the first start.

Both variants have their pros and cons :-)

For the hardware, if not predefined pins of the ESP32 are automatically declared as inputs, this will normally be no problem if this definition is done later by the webinterface.

Thanks again for your help! I will try to get my special hardware work soon - there are a few modifications neccessary because i use some GPIOs of the VS1053 to enable Ethernet and manage the attached class D amplifier. So it will be at the end a special solution which requires adapted software, so updates are not simple. I will send you a unit if all works fine :-)

The issue i have is i not able to use LAN8720 as source 50Mhz clock and have to use esp to feed in GPIO0. And it is the only approach work for my ETH module.

Thanks for the ETH addition!

Hi Ed,

for getting the thing about the fixed pins in the main.cpp round...besides the changes in the pin list above, what does the following in your code?

progpin_struct progpin[] = // Input pins and programmed function { { 0, false, false, "", false }, //{ 1, true, false, "", false }, // Reserved for TX Serial output { 2, false, false, "", false }, //{ 3, true, false, "", false }, // Reserved for RX Serial input { 4, false, false, "", false }, { 5, false, false, "", false }, //{ 6, true, false, "", false }, // Reserved for FLASH SCK //{ 7, true, false, "", false }, // Reserved for FLASH D0 //{ 8, true, false, "", false }, // Reserved for FLASH D1 //{ 9, true, false, "", false }, // Reserved for FLASH D2 //{ 10, true, false, "", false }, // Reserved for FLASH D3 //{ 11, true, false, "", false }, // Reserved for FLASH CMD { 12, false, false, "", false }, { 13, false, false, "", false }, { 14, false, false, "", false }, { 15, false, false, "", false }, { 16, false, false, "", false }, // May be UART 2 RX for Nextion { 17, false, false, "", false }, // May be UART 2 TX for Nextion { 18, false, false, "", false }, // Default for SPI CLK { 19, false, false, "", false }, // Default for SPI MISO //{ 20, true, false, "", false }, // Not exposed on DEV board { 21, false, false, "", false }, // Also Wire SDA { 22, false, false, "", false }, // Also Wire SCL { 23, false, false, "", false }, // Default for SPI MOSI //{ 24, true, false, "", false }, // Not exposed on DEV board { 25, false, false, "", false }, // DAC output / I2S output { 26, false, false, "", false }, // DAC output / I2S output { 27, false, false, "", false }, // I2S output //{ 28, true, false, "", false }, // Not exposed on DEV board //{ 29, true, false, "", false }, // Not exposed on DEV board //{ 30, true, false, "", false }, // Not exposed on DEV board //{ 31, true, false, "", false }, // Not exposed on DEV board { 32, false, false, "", false }, { 33, false, false, "", false }, { 34, false, false, "", false }, // Note, no internal pull-up { 35, false, false, "", false }, // Note, no internal pull-up //{ 36, true, false, "", false }, // Reserved for ADC battery level { 39, false, false, "", false }, // Note, no internal pull-up { -1, false, false, "", false } // End of list } ;

Is this to prohibit a new pin declaration in the webinterface? So if i want to get some pins fixed in the main.cpp and not user changeable in the webinterface, i would:

• change a specific pin in the struct iosetting klist[] from -1 to the GPIO name
• change the GPIO in the progpin_struct progpin[] to "true" (first of the 3 boolean entries)

Is that correct?

BTW: Thanks tsctrl for the feedback, sounds great :-)

@tsctrl : you can apply a 4k7-10k pulldown resistor from the enable pin of the LAN8720 oscillator to ground and wire this enable pin to a free GPIO of the ESP32. This GPIO you can use as PHY_power_pin, so while booting the clock signal of the oscillator is not active and after booting and activating ethernet the GPIO is set to high and the clock signal is then applied to the GPIO0 of the ESP32.

This is the actual workaround for the LAN8720 modules.

BTW: in your log, both Wifi and Ethernet seems to be active. Is that correct?

[Edzelf]

The propping table is used to hold information about the programmable pins.

[tsctrl]

yes, all are active @dreamy1, just i not able to use the external oscillator. try that setup to disable the oscillator but it did not communicate to esp and driver didnt load during boots.

wondering why use LAN8720 instead of W5500 lan module @dreamy1 , @Edzelf?

W5500 is spi based and use lesser pin

[dreamy1]

There are several ways to get ethernet, but LAN via SPI could be a good reason to overstress the spi bus. There is already the VS1053 and the TFT on the same bus (and smooth playback is only possible with a separate task now in V2 of the radio) and LAN takes a lot of additional ressources.
