Gpio rising edge

WebMar 14, 2024 · 3. Unfortunately it is not possible to tell which edge has been detected. If your signal changes slow enough, you could use the actual level of the pin to determine the edge (If IDR & Pin is true, the last edge was a rising one :) ) Or you could use two pins. One to detect rising and one for the falling edges. WebApr 5, 2024 · A GPIO pin can trigger an interrupt when its value changes: either from low-to-high or high-to-low. These events are known as a rising edge and falling edge, …

WebOct 18, 2024 · 3. I try to create bare metal application for TI am335x soc based board. One thing I need to do is to invoke callback1 on rising edge and callback2 on falling edge. From the datasheet I figured out, that simultaneous detection for rising and falling edge could be enabled by writing 1 << pin to RISINGDETECT and FALLINGDETECT GPIO registers. WebIf the GPIO is configured as an output, this value may be written; any nonzero value is treated as high. If the pin can be configured as interrupt-generating interrupt and if it has been configured to generate interrupts (see the description of “edge”), you can poll(2) on that file and poll(2) will return whenever the interrupt was triggered.
