to another. The main advantage of this communication protocol is that its not necessary for both the devices to have the same operating frequency. For example, two microcontrollers operating at different clock frequencies can communicate with each other easily via serial communication. However, a ...
I'm using an ESP32-C3 chip but running into issues because of the boot messages that are automatically sent to the non-USB UART on boot up. I use this UART to communicate with another device and these messages are causing its communications to fail. ...
This setup worked fine when i connected the SD card reading module with the same pin connection as i did before, and it was able to detect and write data on the SD card. Kindly advice if I am missing any point that is making the ESP32-WROOM-32E-N8R2 module unable to communicate ...
Another Question: The only thing I can't understand at the moment is if I need to go through the MFi process just for development to use ExternalAccessory? In terms of creating a fully MFi licensed accessory the answer is, yes. You'd need to join the MFi program to get access to the...
