Receives from software serial, sends to hardware serial.
|
||||
|
||||
The circuit:
|
||||
* RX is digital pin 2 (connect to TX of other device)
|
||||
* TX is digital pin 3 (connect to RX of other device)
|
||||
* RX is digital pin 10 (connect to TX of other device)
|
||||
* TX is digital pin 11 (connect to RX of other device)
|
||||
|
||||
Note:
|
||||
Not all pins on the Mega and Mega 2560 support change interrupts,
|
||||
so only the following can be used for RX:
|
||||
10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
|
||||
|
||||
Not all pins on the Leonardo support change interrupts,
|
||||
so only the following can be used for RX:
|
||||
8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).
