Working on a Port to ESP32 see my suggestion https://github.com/pcbreflux/espressif/tree/master/esp32/arduino/libraries/Ucglib/src/Ucglib.cpp

Tested on a ESP32 inside Arduino IDE with ILI9341 using Box3D, Font, Text and Color

@pcbreflux I'm using this lib with ESP8266. My change is smaller. Take a look: https://github.com/olikraus/Ucglib_Arduino/pull/3

olikraus commented 7 years ago

Will this also work for the ESP32?

if defined(PIC32MX) || defined(arm__) || defined(ESP8266) || defined(ESP_PLATFORM)

pcbreflux commented 7 years ago

hi olikraus,

could try it on monday and give feedback.

have a nice weekend pcbreflux

Hi,

i tried version 1.4 with the esp32, but it didn't compile in my environment:

/Users/dennis/Documents/Arduino/libraries/Ucglib/src/Ucglib.cpp:786:20: error: cannot convert 'volatile uint32_t* {aka volatile unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment
   u8g_data_port[0] =  portOutputRegister(digitalPinToPort(ucg->pin_list[UCG_PIN_D0]));
...

I have to use the fix of pcbreflux again.

Greetings Dennis

olikraus commented 7 years ago

ok, the goal was to make it work for "ESP8266". ESP32 was more an extra wish. Result now is, that ESP32 requires 32 bit arrays.

Jorgen-VikingGod commented 7 years ago

I also used the hack of @pcbreflux to run it on my ESP32 devboard.

olikraus commented 7 years ago

Are there any instructions how to setup Arduiono IDE for ESP32?

Dennis650 commented 7 years ago

Hi,

yes: https://github.com/espressif/arduino-esp32

Greetings Dennis

pcbreflux commented 7 years ago

Hi Olikraus,

test the Patch from Marcos A Sobrino.

Using

Arduino 1.6.13 linux 64Bit and Arduino 1.8 linux 64Bit
Arduino core for ESP32 form https://github.com/espressif/arduino-esp32 (git version 7cef2e2)
ucglib Version 1.4.0 with patch on Line 774
ILI9341 with SWSPI and HWSPI
HelloWorld.ino, GraphicsTest.ini (without line 561 set_clip_range()), Box3D.ino

Settings //Ucglib_ILI9341_18x240x320_SWSPI ucg(/sclk=/ 18, /data=/ 23, /cd=/ 16 , /cs=/ 5, /reset=/ 17); //Ucglib_ILI9341_18x240x320_HWSPI ucg(/cd=/ 16 , /cs=/ 5, /reset=/ 17);

Works fine for me (only some warnings), so respect to Marcos for the small solution.

But only one oddness not related with the patch: on the ESP32 HWSPI works much slower then SWSPI (maybe 2 - 3 times faster).

Have a nice day pcbreflux

Would be great to have full speed support by HWSPI fill screen and changes are flicker too much...

Dennis650 commented 7 years ago

Hi,

@Jorgen-VikingGod @pcbreflux can you please post a pin mapping for HWSPI? I have a IL9431 like seen in the video from @pcbreflux. I tried it, but it won't work. Do you have touch enabled?

Greetings Dennis

pcbreflux commented 7 years ago

Hi Dennis,

using this pinmap https://github.com/espressif/arduino-esp32/blob/ master/doc/esp32_pinmap.png

No touch. Using the same pins for HWSPI and SSSPI.

Settings //Ucglib_ILI9341_18x240x320_SWSPI ucg(/sclk=/ 18, /data=/ 23, /cd=/ 16 , /cs=/ 5, /reset=/ 17); //Ucglib_ILI9341_18x240x320_HWSPI ucg(/cd=/ 16 , /cs=/ 5, /reset=/ 17);

ok,i guess i will order such an ESP32 for further tests. Any suggestion what i can buy from ebay.com?

pcbreflux commented 7 years ago

Hi,

I tried ebay (eckstein in germany) and you can look at analoglamb.com . For me aliexpress is not reliable today. ordered from differend sellers but never came and have to refund after 6 to 8 weeks.

have a nice day pcbreflux

Hi,

@pcbreflux HWSPI is working now, but it is realy slow, as you said.

@olikraus: i ordered a SparkFun ESP32 Thing (from eckstein germany, too).

Greetings Dennis

olikraus commented 7 years ago

so you mean this https://eckstein-shop.de/SparkFun-ESP32-Thing-Espressif-Inside-WLAN-BLE-IoT-Modul or this http://www.exp-tech.de/sparkfun-esp32-thing correct? Maybe i get this thing from exp-tech... I had previously ordered from exp-tech already. :-p

Hi,

yes. And thanks for your great work on this lib.

When i try to upload, i get the followig error: A fatal error occurred: Failed to connect to ESP32: Invalid head of packet ('r') any idea?

Arduino IDE: 1.8.1 Board: ESP32 Dev Module

olikraus commented 7 years ago

ESP32

defines by the compiler

define __XTENSA_EL__ 1

define xtensa 1

define XTENSA 1

define XTENSA_WINDOWED_ABI 1

defines by Arduino IDE: ESP_PLATFORM

pcbreflux commented 7 years ago

hi, before uploading you have to bring the esp32 to donwload mode gpio0 to low (long press) and reset (short press) and sometimes make shure to disconnect any serial monitor. hope this helps.

Greetings pcbreflux

hmmm... whatever i try it is not working.

pcbreflux commented 7 years ago

Hi,

have you try connecting with the serial monitor (115200 baud) and just watch the debug output after reset? then go to download mode ...... read somthing like 'waiting for download ....'?

olikraus commented 7 years ago

I had a look at your code again: https://github.com/pcbreflux/espressif/blob/master/esp32/arduino/libraries/Ucglib/src/Ucglib.cpp

The problem is, that i du not understand your code. Why is port = 0? The ESP32 has at least two port registers.

Anyhow, i give up here. Maybe once this ESP32 is more stable and reliable...

pcbreflux commented 7 years ago

hope you esp32 is not broken. but after the "waiting for download" can you try to close the serial monitor before uploading? what board, baudrate and usbport you are using?

Closing the serial monitor does not make a difference. Still, it does not work. I do not think its broken, i just think the the upload tool does not work. My ESP thing has a very new version (13 Sep 2016), so maybe it is because of this.

Dennis650 commented 7 years ago

Hi,

i have installed Arduino 1.8 on a Mac. I just downloaded an example and uploaded it to the Esp32 through the Arduino IDE by clicking on "Hochladen". There is no need to pull GPIO0 to low.

Here is a guide: https://learn.sparkfun.com/tutorials/esp32-thing-hookup-guide#installing-the-esp32-arduino-core

Greetings Dennis

olikraus commented 7 years ago

I did follow exactly these instructions. I have used two different linux machines. Always the same error. Ok, i have not yet used Mac or Windows.

Dennis650 commented 7 years ago

Hi,

there were a lot of work the last days on arduino for esp32. Maybe you can try again and post an issue if it doesn't work?

But there is also an new ticket for slow hardware SPI: https://github.com/espressif/arduino-esp32/issues/149

should work with 1.5.x
