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.
