Port pin level value

WebJul 27, 2024 · These pins are also referred to as P1.0 to P1.7 (where P1 indicates that it is a pin in port 1 and the number after ‘.’ tells the pin number i.e. 0 indicates first pin of the port. So, P1.0 means first pin of port 1, P1.1 means second pin of the port 1 and so on). These pins are bidirectional pins. Pin 9 (RST) – Reset pin. WebJul 27, 2024 · I had no clue that assigning the variable to Pin B0 was more time hungry than using the "define" statement. The macro was also a new revaluation.
