SerialPassthrough sketch
|
|
|
|
Some boards, like the Arduino 101, the MKR1000, Zero, or the Micro,
|
|
have one hardware serial port attached to Digital pins 0-1, and a
|
|
separate USB serial port attached to the IDE Serial Monitor.
|
|
This means that the "serial passthrough" which is possible with
|
|
the Arduino UNO (commonly used to interact with devices/shields that
|
|
require configuration via serial AT commands) will not work by default.
|
|
|
|
This sketch allows you to emulate the serial passthrough behaviour.
|
|
Any text you type in the IDE Serial monitor will be written
|
|
out to the serial port on Digital pins 0 and 1, and vice-versa.
|
|
|
|
On the 101, MKR1000, Zero, and Micro, "Serial" refers to the USB Serial port
|
|
attached to the Serial Monitor, and "Serial1" refers to the hardware
|
|
serial port attached to pins 0 and 1. This sketch will emulate Serial passthrough
|
|
using those two Serial ports on the boards mentioned above,
|
|
but you can change these names to connect any two serial ports on a board
|
|
that has multiple ports.
