SLIP-Send-CRC.ino

SLIP-Send-CRC

Send a SLIP package over the serial port every 5 seconds.

Boards:

AVR, AVR USB, Nano Every, Nano 33, Due, Teensy 3.x, ESP8266, ESP32

1. Upload this sketch to one Arduino.
2. Upload the SLIP-Receive-CRC.ino sketch to a second Arduino.
3. Connect the TX pin of this Arduino to the RX pin of the second Arduino.
4. Open the Serial monitor of the second Arduino.

It should print the following:

Received packet: Hello, world!
Size:            OK
Checksum:        OK

For boards where Serial is not a hardware UART, use Serial1 as the stream for the SLIPStream.
