Re: Using esp_timer to create another one-shot from the call back of another one-shot

esp_timer_handle_t new_oneshot_timer; pst->savedHandle = new_oneshot_timer; ESP_ERROR_CHECK(esp_timer_create(&oneshot_timer_args, &new_oneshot_timer)); new_oneshot_timer is on the stack. You then assign the value of the (uninitialized) handle to savedHandle, which is pretty useless. The timer is cr...

Re: Timer frequency question

I think you're running into the fact that interrupts just aren't that quick on the Xtensa.

Re: esp8266-12e node mcu is not detecting adxl345

This is a forum for the ESP8266 ESP32, not the ESP32 ESP8266 (thanks rudi). Suggest you ask your question on e.g. https://bbs.espressif.com/ or on a nodemcu-related forum instead.

Re: what ESP32D0WDQ6 is 160Mhz

There are versions of the ESP32 which are only certified to work at 160MHz. Seems your development board has one of those chips.

Re: Runtime ISR crash

That's... well, if it's not a bug, it's pretty close to it. You can fix it by disabling FREERTOS_CHECK_PORT_CRITICAL_COMPLIANCE (menuconfig -> Component config -> FreeRTOS -> Tests compliance with Vanilla FreeRTOS port*_CRITICAL calls ). I'll raise an internal issue to make the CAN driver work witho...

Re: Interrupt WDT

I think you're conflating two things here: one is wake-up, the other one is the interrupt. At the moment, it seems you have both set to level, that is, while the line is high, the CPU will keep waking up (which I think is what you want) and while the line is high, it will also keep triggering the in...

Re: Interrupt WDT

Well, if any, you configure the GPIO as a level interrupt, meaning the interrupt keeps triggering as long as the line is high. Perhaps that is your issue?

Re: How to modify pre-built (esp32 IDF)source files.

You could try adding the Arduino environment as a component to your esp-idf project:

Re: ESP32 - No connectivity

No idea on why pinging fails, but the board may not show up in your routers list because lists like this tend to display the DHCP leases only. You could test that by having some other device (e.g. laptop) connect to the AP with a static IP and see if it shows up.

Re: Interrupt WDT

How do you setup your GPIO and/or interrupts?
