Using PI4 buster
currentlly I'm using pin8 and pin 10 to read data from Arduino (which is Serial0)
I need to read another Arduino , so I need to connect it to another serial port
when I look at the pinout I see I can use pins 27&28 as Tx2\Rx2
do I need to change something in the condig file? boot.txt in order to work with this pins?
or I can just connect and in the code write /dev/Serial2 ?
