I thank @ZinggJM for the effort to create these libraries. They are exactly what I was looking for. My display is "GoodDisplay GDEW027W3 I am using the GxEPD2 library and was wondering; are levels of gray possible and I haven't found it yet. If not could they be? Is this something I might be able to kludge together from the multicolor display code? Thanks John 1 post - 1 participant Read full topic ..read more

Keyboard one bad after using ESP32 externally powered

I made a circuit with esp32 3.3V module. It was powered by 12 v adapter. Then the 12v was stepped down to 3.3v by a buck convertor and fed into Vin of esp32 module. The esp32 module was also connected to the computed via USB cable to read the data it was generating and sending. When the usb cable had connected the esp32 to the computer, I noticed that the mouse and keys were hanging and not responding immediately. Now after many times using this, the g and h keys of my computer don't work, along with " and up keys. Why? 2 posts - 2 participants Read full topic ..read more

I've been unable to get my https://docs.arduino.cc/arduino-cloud/hardware/lora/ tutorial sketch to connect to my Arduino Cloud Thing. I have a Browan gateway setup with my TTN account, conr2286, and I can see received uplink messages (GatewayData.png) from my 1310. The EUIs in the JoinEUI seem to match those in the TTN application (app.png) that the Arduino Cloud created using my Arduino TTN account, conr2286-dc (yes, I have two TTN accounts now). The serial console output (SerialConsole.png) reports the failure (I have LORA_DEBUG directed to Serial and DebugMessageLevel at 4). The forum won't ..read more

I want to use this lib in an Arduino sketch. It claims that This library is compatible with all architectures so you should be able to use it on all the Arduino boards. but it seems to be dependent in some Pico SDK, could I use it on an Arduino Due? (I know due already has a CAN controller) 1 post - 1 participant Read full topic ..read more

Usb Microcontroller Integration

Hello, is it possible for a microcontroller like the ESP32-S3 or RP2040 to access keyboard outputs while the computer remains the host? In other words, can the microcontroller read the data sent from the keyboard without being the host, while the computer continues as the primary host? Through this, could the microcontroller, for example, control an LED or create shortcuts when a specific key on the keyboard is pressed, without affecting the keyboard's functionality for the computer? Thank you in advance for your assistance! 2 posts - 2 participants Read full topic ..read more

Hello, magicians. Hate to disturb people with dumb questions, But I am struggling with setting up mask and filter for ID on canbus. I have read alot of topics on this matter and it was easy with different library, but... never easy quest .. library I used before was conflicting with another that I need for the project... My hair went grey with trying to establish whats going on. Now I am using this library: mcp2515.h And I need to filter by ID - 418. I will need other IDs at a later stage, but help with setting first one up will be sufficient for me to continue on my quest and hopefully grasp ..read more
