There is some documentation here, though I didn't see much that explains how to register and use the SPI interrupt routine: https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/spi_master.html and further, the use of interrupt driven SPI seems a bit bizarre in th...
GPIO6 to GPIO11 GPIO14 GPIO15 Interrupt Pins All above-mentioned GPIO pins can be configured in interrupt mode to detect positive edge, negative edge, or level triggered. For more information refer to the following article: ESP32 Interrupts and Timers with PIR Sensor using Arduino IDE Strapping...
Maybe i misunderstood what you are trying to do, but I would use the 32kHz square wave output from the DS3231. You could keep a counter running at 32kHz interrupt on the ESP32 that is reset by the GPS pps signal. If it goes above the 32kHz count => gps pps signal is lost, re...
slv_rx_buf_len and slv_tx_buf_len, The size of the RX and TX buffers. The buffers are only needed if the ESP32 is being used in the slave mode. Since we are using it as a master, we will keep these buffers as 0. intr_alloc_flagsis to set the interrupt flag for the I2C. ...
Hi, How can I use the "ESP_INTR_ALLOC() API to pin a interrupt to a specific core, and can i be sure that the ISR function would be on the same core? I can nowhere find a example for this question Grtz, YvesWiFive Posts: 3529 Joined: Tue Dec 01, 2015 7:35 am Re: How ...

The following table shows which pins are available for interrupt detection on AVR Arduino boards. Please refer to the datasheet of your development board if you use a non-AVR board, for example, an ESP32, to find interrupt-capable pins....
Guru Meditation Error: Core 1 panic'ed (Interrupt wdt timeout on CPU1) And I try to config the interrupt watchdog but can't find a way. In ESP-IDF you can config interrupt watchdog in Project Configuration Menu (sdkconfig) :https://docs.espressif.com/projects/esp ... figuration But ...
RTC.cancel(alarm_id=0): used to cancel a running alarm. The RTC class provides these methods to configure an interrupt… RTC.irq(*, trigger, handler=None, wake=machine.IDLE): creates an interrupt object that’s triggered by the RTC alarm. It takes three parameters: trigger, handler, and...
An external interrupt means an external interference in the normal functioning of the system. This interrupt can come from the user or any other device present among the networks. A common use of interrupts in ESP32-CAM is to wake up the microcontroller to perform a task. In ESP32-CAM, GP...
