WebJan 28, 2024 · Then the ESP32 came out - and well, you can use it in exactly this manner! But lets start with the beginning: In the espressif folder esp-id/fexamples you can find the gpio_example. Here we have (selfmade) interrupts. The interrupt service routine then unblocks an RTOS task with xQueueSendFromISR. WebAlthough the ESP32 has 48 GPIO pins in total, only 25 of them are broken out to the pin headers on both sides of the development board. These pins can be assigned a variety of peripheral duties, including: 15 ADC channels. 15 channels of 12-bit SAR ADC with selectable ranges of 0-1V, 0-1.4V, 0-2V, or 0-4V. 2 UART interfaces.

MicroPython: Interrupts with ESP32 and ESP8266

WebI can get PWR and MOT interrupts. I never get RTC interrupts. If I poll the MOT, RTC or the PWR pins, in my loop(), those three pins will reflect their actual state and do change accordingly. I just can't get the RTC pin to generate an interrupt. The only thing I can think of is that maybe that pin can't handle interrupts? The pins are: WebMay 5, 2024 · Further inner working of the code are: The Adafruit OLED library is incuded, as well as the sleep library and the Pin Change interrupt library.
