I am working in an AUTOSAR project on a STM32 NUCLEO-F767ZI board and I have to write the value for a port in the DIO module. I know that there is a function called HAL_GPIO_WritePin(), but how can I make to write the value for an entire port?
You can do that by writing the value for each channel in that port.
The ports usually have 16 channels so the value you want to write is a 16 bit number containing 0
and 1
(LOW
and HIGH
). So for each bit in that number you call the function HAL_GPIO_WritePin()
and use the parameter RESET
for 0
and SET
for 1
to write the value to the corresponding channel.
