WebSTM32 GPIO Ports. Each of the general-purpose I/O ports has two 32-bit configuration registers, two 32-bit data registers, a 32-bit set/reset register, a 16-bit reset register, and a 32-bit locking register. Each I/O port bit is freely programmable, however, the I/O port registers have to be accessed as 32-bit words (half-word or byte accesses ... WebFeb 12, 2024 · The right way to do this is to have the interrupt service routine just wake up a task. Put your current code from gpio_isr_handler () in a task in an infinite loop with a , start the task in app_main () and have gpio_isr_handler () just wake the task. Use vTaskSuspend () at the start of the loop to have the task wait till it's woken up.
