build for Lolin S2 Mini ESP32-S2[Issue]

[ddijanic]

I bought esp32 with 2 mini thinkers, that it will work. but s2 is a bit different when it comes to sending programs to it.

I struggled for 2 days, I didn't succeed much. if someone knows how to set this up, if not, wait again +30 days but I managed to enter wled, they have it for s2 build.

this is how it looks with wled

I don't have a Lolin S2 Mini, but this is how I would configure it for the first run and please note, I didn't check for the pinning!

[BlueAndi]

And use the Development branch, because there is the latest esspressif32 platform and the bugfixed esptool available.

[BlueAndi]

Ahh ... and I realized in this moment, the esp32-s2 is only a single core mcu. :-/ Therefore I updated the configuration I posted previously. Additional this short patch is necessary too. esp32s2_ResetMon.patch

[ddijanic]

thank you for your effort and time. he translated it, i sent it to esp. I did not see the wifi host, after holding buten on pin 4. I'll try it today with the panel to see if it works.| serial monitoring does not work on esp s 2, of course :D and I use the Development branch, I will let you know what happens...

ps. I tried the SHT3x sensor, it says it's 30 degrees, but it's 22 :D I tried to hold for Soldering Iron near, 20 seconds, temperature stands at 30: D

then I found one DHT 11 he writes 23-24. temperature offset would be good maybe...

[BlueAndi]

I pushed the WEMOS Lolin S2 Mini support to Development branch. Serial connection should work after a power reset. The USBCDC driver will be initialized.

Did you test the sensors with the Lolin S2 or another board? I am confused ... thought the Lolin S2 is not working right now.

Did you check the datasheet of the SHT3x regarding accuracy, etc? I will have a look whether I have a SHT3x somewhere here to verify it too.

[ddijanic]

Sensors tested whit ESP32-WROOM-32U, whit build esp32doit-devkit-v1. temperatura works but dht11 is off by 2 degrees. SHT3x is off by 8 degrees..

Datasheet SHT3x-DIS SHT30 Accuracy tolerance1 typ., 0°C to 65°C 0.3 °C SHT31 Accuracy tolerance1 typ., -40°C to 90°C 0.3 °C SHT35 Accuracy tolerance1 typ., -40°C to 90°C ±0.2 °C Repeatability2 --------------- Low 0.24 °C --------------------------------Medium 0.12 °C ------------------------------- High 0.06 °C Resolution-------Typ -------- 0.015 °C

I left the esp s2 at work :D , tomorrow morning I will try the new Development branch. to upload.

[ddijanic]

WEMOS Lolin S2 Mini Development branch not working, upload 100% and reboot , but no error on panel E4. after upload littlefs files, not working. on board led fleshing, but no output on led panel. serial monitor not working for this bord, so canot se whats the problem. reboot with pin 4 to gnd. no wifi hotspot. thanks we tried....

PS. I tried yesterday. to replace one image from OpenWeatherPlugin. WITH fire.bmp AND ADDED fire.sprite. I wanted to see if the animation could go along, To make clouds that move etc for the openweatherplugin. But fire was there, but it wasn't animation of course

I didn't find where it says how to insert animation into IconTextPlugin or somewhere. it only says how to make it, not how to put it :D

this is very cool and eazy https://www.piskelapp.com/p/create/sprite it has png,gif, and .C file out put, maybe it would perhaps be easiest to add C think :). for OpenWeatherPlugin, IconTextPlugin and new plug 8x 32 pic and animation plug :D

Does that mean you saw the E4 on the panel or no error at all?

on board led fleshing, but no output on led panel.

The Pixelix was in the error state. I updated the Development branch. Try again, the onboard LED will show the error number in case its an low level error.

reboot with pin 4 to gnd. no wifi hotspot.

Hmm ... maybe the button driver failed. You will see it with the error id flashed with the onboard LED. And the error itself prevents to go the access point mode.

---

Where did you connect the LED matrix? The WEMOS Lolin S2 has no GPIO27, as I can see. Did you update the ./lib/HalLedMatrix/src/Board.h ?

thanks we tried....

Means you give up? :-)

The OpenWeatherPlugin doesn't support the spritesheet at the moment. I thought about it as well, but was not priority 1. Currently I am facing the problem that for 4 MB flash modules, the flash is nearly full. But of course with 8 MB or more, the plugin can be updated to support it.

I didn't find where it says how to insert animation into IconTextPlugin or somewhere. it only says how to make it, not how to put it :D

https://github.com/BlueAndi/esp-rgb-led-matrix#how-can-i-use-animated-icons Only short I know ... :-)

I know the PISKEL editor. The drawback with png and gif is the much more complex handling of the formats. The bitmap file format is easier and don't need to much power and space. Providing them as .c files makes it inflexible, because you need to compile it in everytime you change. Please consider that there are not so many libraries somewhere providing the features for an MCU, like the esp32. And please consider the license model of them as well. Goal is to stay with MIT or compatible license. The bitmap parsing I implemented by my own, to get it with low space consumption and fast loading.

IconTextPlugin and IconTextLampPlugin e.g. support .bmp and spritesheets. The icons can be easily updated via webinterface, because they are in the filesystem.

no.

and to somting like [frame1], [frame2]

we can't use text only because of the license?

Ldr I tried using ky-018, I get between 0.5v and 3v on pin 34. and the sensor plug doesn't see the sensor, and I can't turn on the automatic light intensity.

I'm waiting for it to arrive from China LdrGl5528

[BlueAndi]

Which LED matrix orientation does your matrix requires?

on bord led is blinking, long on, off short, on short, off short, on long.

My fault, had in mind the LED is low active. Fixed in Development branch. But it looks like the I2C pins are wrong and yes, they are. I updated the pinning to

• SDA 33
• SCL 35
• LDR 1
• LED matrix data out 21
• I2S removed

wifi ap mod not working, 4 to gnd.

Yes, as long as the board is in error state, the wifi ap won't be spawned.

PISKEL editor white c output make text liki this for 1 frame of 8x8 grid:

Not as efficient than as binary like bmp. :-)

No, I meant the libraries for handling png, gif and etc. formats.

With the esp32doit-devkit-v1 board, I guess? We should not mix it here, to not confuse ourself. :-)

[ddijanic]

Which LED matrix orientation does your matrix requires?>

matrix is okay, it works with master build.

With the esp32doit-devkit-v1 board, I guess? We should not mix it here, to not confuse ourself. :-)

yes, I use esp32doit-devkit-v1 board for test, so i know matrix is okey :) but ldr not working, and dht11 temp offset would be nice to :)

[ddijanic]

https://ibb.co/FDkNW0h

ldr is now recognized. in the sensor plagu he sees it. I can turn on auto brightness. but it goes up and stands only up. the plug sensor reads from 1 lux to 4000 lux, sometimes it goes even higher and says MAN :D pin 1 gets from 0.05v to 2.9v on light.. but the light always shines the same. they increase to 70 percent and will not decrease when I cover the sensor

can you give me the code just how to turn on spritesheets in OpenWeatherPlugin?

[BlueAndi]

Great, its working.

As its getting darker there is a certain threshold after the LDR is not recognized anymore. Caused by low voltage and bad ADC accuracy. Therefore I am thinking about removing the automatic LDR detection and replace it with a manual activation in the settings.

The display brightness doesn't react immediately on brightness changes by intention. There are two kind of filters. One detects short term changes and the other long term changes. If the tendence of both goes into the same direction, the brightness will be adjusted smooth. See https://github.com/BlueAndi/esp-rgb-led-matrix/blob/Development/src/Gfx/BrightnessCtrl.h https://github.com/BlueAndi/esp-rgb-led-matrix/blob/Development/src/Gfx/BrightnessCtrl.cpp

can you give me the code just how to turn on spritesheets in OpenWeatherPlugin?

You will find a simle example in the IconTextPlugin ... see e.g. this part: https://github.com/BlueAndi/esp-rgb-led-matrix/blob/e8734273196b778a55e127247a15f6f71fb122ac/lib/IconTextPlugin/src/IconTextPlugin.cpp#L189-L196

I updated the Development branch again and refactored a little bit for easier maintenance. Please check again. If its successful, I would like to close this issue regarding the S2 mini board.

OpenWeatherPlugin is broken on dev s2 , its active is set up. Debug, Logging, ther are no errors, all green

"apiKey": "87e6a2b3ddd528e530acfd1cfc3b68e3", "lat": "46.100376 ", "lon": "19.833549", "other": 0, "units": "metric"

but its showing onley ? does it matter if two pixelix use isiti api?

btc plug works. sunsetworks, all works except OpenWeatherPlugin

this work great. https://github.com/Aircoookie/WLED/tree/main/usermods/SN_Photoresistor you have little to play around with the whales, but after 3 minutes its done I have made 2 clock whit this and its good.

I've seen a modified one that's even better, I think it's easier to adjust. I need to find where that one is.

DEAL :)

[BlueAndi]

Thanks for the feedback.

[ddijanic]

for spritesheets in OpenWeatherPlugin

if (false == m_bitmapWidget.loadSpriteSheet(FILESYSTEM, getFileName(FILE_EXT_SPRITE_SHEET), getFileName(FILE_EXT_BITMAP))) { (void)m_bitmapWidget.load(FILESYSTEM, getFileName(FILE_EXT_BITMAP)); } add this at top / Initialize sprite sheet parameter filename extension. / const char* IconTextPlugin::FILE_EXT_SPRITE_SHEET = ".sprite";

not complain build..

[BlueAndi]

@ddijanic I asked you already on Discord about it. :-)
