ESP32 Detach Interrupt (External Interrupt Disable) You can of course disable the external interrupt functionality for any interrupt pin whenever you want in your code. By using this function from Arduino Core, you can disable any external interrupt pin. 1 detachInterrupt(GPIO_pin); ESP32 ISR (...
pin参数:IO号,绑定引脚编号。 void (*)(void)参数:函数指针,指向中断服务函数。 mode参数:中断模式。 5.void attachInterruptArg(uint8_t pin, void (*)(void*), void * arg, int mode); 这个API函数与上面一个API函数非常相似,所以我们只讲不同之处,首先这个绑定的中断服务例程是一个带传参的例程。 首...
Pulling GT911 touch interrupt pin down with a resistor with ESP32 S3 controller Quote Sun Oct 27, 2024 9:12 am Hello, I have this RGB 7" display I purchased from aliexpress, it runs ESP32-S3 and I believe ST7262 RGB display driver. The problem is in the initialization of the GT...
Hello, I would like to ask about setting wakeup from light sleep on ESP32-C3. I am not able to configure wakeup and also attach the interrupt to the same pin (non RTC pin). Any attempt to attach or detach interrupt on wakeup pin cancel the wakeup function and vice versa. Is there...

In the case of esp32s3 camera, it was not possible to trigger the DMA interrupt and LCD_ Camera peripheral's vs pin interrupt, look for ll_ Cam. h did not find any errors and cannot find answers to related issues online. May I ask if it is due to the lack of flash and PSRAM ve...
About the way it may work on esp32c3: I also had the same suggestion: wake up on low or high state and then interrupt will be triggered (not edged). But I guess the application logic will be really complex. For example, an external IC interrupt pin uses a latched state interrupt and...
