thx I'll try later to see

I have removed de fastled library, it works but the problems remain.

you can try a digispark with attiny85 onboard which can emulate a hid keyboard, but you must investigate if it can send control keys such windows, alt or combination of keys. You can program it with arduino. [image: 1621350558845-digispark.jpeg]

@aattila Very great! arduino-esp32 version 1.0.5-rcX The compiled project will not work consistently because there is a wifi related bug and sometimes the button A (left) will receive the pushed event (many events) This problem should be cured after wifi.setSleep (False) after wifi.begin. Please refer to the following. https://macsbug.wordpress.com/2021/05/02/buttona-on-m5stack-does-not-work-properly/

Hello @sharek you don't need both ext0 and ext1 for the two buttons. You should be able to cover both buttons with ext1 by adding both to the bitmask: #define BUTTON_PIN_BITMASK ((1UL << 37) | (1UL << 39)) Thanks Felix

Thank you for your hard work.

I've been trying to get this to compile/install using the Arduino IDE and i'm not getting anywhere... Once installed, the M5Paper just continuously reboots, flashing the screen on and off. Watching the serial monitor I see this repeated on each reboot... Any suggestions? Rebooting... M5EPD initializing...OK Guru Meditation Error: Core 1 panic'ed (LoadProhibited).

can you please send code to dhalse@gmail.com

@kilam Well done, i have similar for STEAM project, i realized a grove interface for onewire ds18b20 to monitor water temp in an aquarium at the same time reading ENV II sensor

@lumpynose the coreink default behaviour when you do a screen refresh (instead of partial refesh) is to change the whole screen to black and white several times as its basic e-ink function. The coreink has a slow refresh rate of 15 seconds between refreshes and this is pointed out quite a few times in uiflow!

@world101 So I figured it out: On that particular module I connected it as follows: Left pin on module labeled 'S' to 5v on the righthand side of M5Stack (red wire) Center pin on module (not labeled) to GND on the righthand side of M5Stack (yellow wire) Right pin on module labeled '--' to pin 2 on the righthand side of the M5Stack (orange wire) After you compile and upload the app tap the module to see the "Tap" message.

Hi ! Thanks for this, it was very usefull to me for handling my brand new M5 CoreInk :) It should definitely be in the Github examples from M5.

@calin I know it’s an old topic (!) but where could I find the Arduino ide code for the Weather Station? Hope you can help 😊
