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 ... WebDec 14, 2024 · The ACPI driver handles the listed GPIO interrupt and evaluates the Edge, Level or Event control method for it. The control method quiesces the hardware event, if necessary, and executes the required Notify operator on the event source device's namespace node. Windows then sends the notification to the device's driver.

Use vTaskSuspend () at the start of the loop to have the task wait till it's woken up.

WebOct 15, 2024 · So the interrupt handler got no chance to run at all. The solution is to set intr type to GPIO_INTR_DISABLE during the initialization, and after everything is done and called, set the intr type to high or low level.
