WebDec 21, 2024 · I'm having a problem with "high-frequency" GPIO interrupt. I have a signal coming from another microcontroller that generates a 50us low pulse every 12ms and I capture this pulse using a falling-edge interrupt to send a task notification to a task with the highest priority in all my program. static void IRAM_ATTR scl_isr_handler(void* arg ... WebMar 21, 2024 · By btidey - Tue Mar 19, 2024 3:21 pm. If the pulse is long enough then reading the GPIO during the service routine will tell you the current state and therefore which was the last edge. If the pulse is so short that it has reverted before the service routine can read it, then knowing whether it was the rising or falling edge is a bit moot anyway.

In part 1 of this series, we created basic wrapper classes to easily access the GPIO functionality using C++ methodology. However, there are some IO features that we are not utilizing. In this tutorial, we are going to implement input interrupts for the ESP32.
