Hello,
I configured a GPIO as an interrupt and wrote a callback function for this GPIO.
At the end of the callback function, interrupt flag is cleared. Inside this callback function, a task is notified. Before jumping to the task, interrupt flag is cleared at the the end of the callback function.
However, I use this GPIO's status (HIGH, LOW) in order to read some registers in the task. Because I clear interrupt, I am not able to read this pin as HIGH. Operating system is FreeRTOS. That's why, I can not put this read operation inside Callback function because I use SPI_send function in this read operation.
How can I make read operation without clearing the interrupt flag?
