I'm working with Thread and got it, kind of, working with a C6 acting as border router and several H2's. However, I still try to understand the concept of Thread, regarding the dataflow. I have several, interconnected nodes which needs to be battery operated, but still work as a minimal thread devic...

Hello ESP_Sprite I'm not using SENSOR_VP/VN for anything anymore - thank you for pointing that out. Also, yes I'm afraid to have a short circuit, so I might go for for your solution at some point, but I've decided to go for the simple solution without the 5-way joystick and just a simple button, so ...

Hello experts. Newbie here. I have this little project, which I'm working on - it features an ESP32-WROVER, as well as a e-ink display. It wakes up, updates the screen every hour, then goes back to sleep. http://www.vandret.dk/files/esp32connections.png My problem is that I would like to add an inte...

I made a breadboard circuit, using the older NodeMCU ESP32 development board, connected to a Waveshare E-ink display (7-color), which works fine. Afterwards, I made a print and bought some ESP32-S2-WROOM processors, but I'm having some problems with them, as the display won't display anything and Wi...

I've dived a bit deeper into this matter. You may be right - however, I discovered that the code, showing the data is run twice. void Eink::showErrorOnScreen(String text) { display.init(); Serial.println("I'm being run once"); display.setTextColor(GxEPD_BLACK); display.setRotation(2); display.setFon...

Hello. I have an ESP32, connected to a Waveshare 5.65" 7-color Eink-display. My problem is that the screen is not always displaying the image/text as intended. If you look at the image below, you can see that it has a very distinct red-like tint and the black appears a tad faded. This issue appears ...

I have a little ESP32-circuit, that updates an eink display (Waveshare with integrated controllerboard), once and a while. display.init(); display.setTextColor(GxEPD_BLACK); display.setRotation(0); //display.setFullWindow(); display.firstPage(); do { // Set the individual pixels to a color (7 in tot...

Wow, I didn't know about ESP-IDF.
Thank you for your help.

Hello ESP32 experts. I’m working on a battery-powered device for monitoring some simple peripherals, display status on a tiny e-ink display and send/retrieve data using Wi-Fi. However, I would like the device to be updateable, in case there are bugs and updates for new devices and functionality. I r...

Hello experts. I have an ESP32-S2 and an external unit, which is wired up to Serial2 (pin 16/17 and CTS on pin 8). The external unit can be accessed using a built-in USB->UART controller and I can open a terminal and submit HEX-commands, manually. Now, I disconnect the USB and cun all communication ...
