Hi,
I want to use the wfi instruction in my code. I'm sending a command to a module and wait for the reply.
I have configured UART communication with the module. Will it be good to use wfi() instruction? I know that it will turn the cpu to power down mode.
Instead I can use some arbitrary delay, but the time taken for the reply is varying in nature.(.7 to 2 sec)
What if I poll the Interrupt flag? is there any alternate solution ?
Thank You.
I think you can use WFI.
