Hello @LukeS I don't think the RGB LED has been integrated into M5Unified library for M5AtomLite. Even for M5AtomS3 the code for the RGB LED is kind of outside M5Unified library, e.g. in utility/LedDisplay.c. All I can find in M5Unified is the GPIO definition for the RGB LED for different M5Stack devices. However I don't think they are used. For M5AtomLite the RGB LED GPIO is (re-)defined and used from here. And for M5AtomS3 it is (re-)defined and used from here. Thanks Felix

and when I try to test 100x by putting my finger... I have Add user result: 0 but the chance is 1/100. So could it be the fingerprint unit is broken? User added successfully! RxBuf[0]: F5 RxBuf[1]: 3 RxBuf[2]: 0 RxBuf[3]: 0 RxBuf[4]: 0 RxBuf[5]: 0 RxBuf[6]: 3 RxBuf[7]: F5 RxBuf[8]: 0 1

@lukevancelave The rtc (Real Time Clock) demo is very good and you can modify it as you like or use it as an example for your unique project. see here! https://github.com/m5stack/M5StickCPlus2/blob/master/examples/Basic/rtc/rtc.ino

I already tried but without any results, i have a ST7789V, with the TFT_SPI library it works well but not with the M5Stack library....

@casascius Interesting. In my case I'm using real certs from my cloud and it works. I don't know how a DNS name would work outside of localhost names. My main issue stated above was that I want a connection to stay open, and I wasn't able to figure that out. thanks.

Same problem, Same solution (with Platformio)

Do they work if you write the UIFlow firmwares to them using M5Burner? Are you programs actually supposed to display things on screen?

Hello @Steve1 I had success with the following converter settings. [image: 1704017737690-iconconvert1_20231231.png] [image: 1704017750557-iconconvert2_20231231.png] This creates a array size of 8192 - same as the stock icons and displays correctly using the DrawIcon() function from the Weather app. // array size is 8192 static const uint16_t IconCloud64x64[] = { 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, Note: I had best results converting jpg using above converter. (png did not work for me and always created an all zero array.) Thanks Felix

Did you get it sorted? I started to post the formula, but I realized that you need to edit the application. I say “application” because it is confusingly written in an advanced, professional C++ style, not the fun Arduino IDE style where everything is spelled out and you just edit the line. I mean: the loop is empty. (!) I don’t have a ePaper to try it. SHT30.h line 30: myData.sht30Temperatur = (int) M5.SHT30.GetTemperature() * ((9.0 / 5.0) + 32.0); -Terry

Hello @Steve1 you are very welcome. Thanks Felix

Hello @samarkh sorry, no idea when and if such a library will be developed. That said, maybe this example helps? Thanks Felix

@steve1 yes the delay is normal as it takes time for the image request to be sent to the host and the host to send the image to the paper. This happens when requesting images from all devices in the M5 range

Thanks @teastain for the hint with USB CDC on Boot! I forgot to mention that I am on PlatformIO but the snippet shown below added to the platform.ini file helped me to solve the problem. Previously I didn't had to specify any build_flags to see the Serial output, so maybe this is a change introduced by PlatformIO. monitor_speed = 115200 build_flags = -D ARDUINO_USB_MODE=1 -D ARDUINO_USB_CDC_ON_BOOT=1 Best Marc

I am just starting out with the M5Paper and a lot of things are taking some getting use to. I thought about deleting this thread when I found out how easy the solution was but then I thought that maybe this will help someone else. So here is the solution: You have to declare a font for use in the canvasOP. So adding his line after creating canvasOP fixes the problem: canvasOP.setFreeFont(&FreeSerif24pt7b);

Does anyone have A-Explorer and Bridge saved anywhere? Seems like dsiberia9s account doesnt exist on Github anymore so it seems lost in time otherwise :(
