I am trying to use my arduino from the CLI, but I am having trouble understanding changing the state of pins.
I am wondering if there is a function available in avr-libc that is analogous to the digitalWrite(ledPin, HIGH) available in the arduino environment.
I have seen PORTB = 0x20 which would set pin 6, but this is not readable and I do not understand the PORTx sequences.
Any help or explanation would be much appreciated
Thanks in advance
