Learn how the UART serial communication protocol works with the ESP32 using Arduino IDE: the basics of UART, default and custom UART pins, basic functions, communication between boards.
The I2C example was named “Wire” in the Arduino example. ProcedureIn this example, we use Ameba as the I2C master writer, and Arduino as the I2C slave receiver.When the I2C slave receives a string sent from I2C master, it prints the received string....
I had it working with Arduino Nanos and NRF24L Wi-Fi modules. Now I am converting it to use a ESP32 and ESP_NOW for communications, the NRF24L's give me troubles now and then plus it reduces the hardware I need. I have the ESP_NOW working if I send static text, "TEXT", but...
Serial.begin(31250); is the same number specified under Hairless MIDI >> Preferences >> Baud Rate (I used 9600, see the image above, I had to replace line Serial.begin(31250) with Serial.begin(9600) in all the example Arduino sketches in this instructable). Normally when you create MIDI...
