So this is weird.. after doing some testing it seems the use of #define for the GPIO pin is causing the problem. Changing it to: constexpr int INT_GYRO = 23; and the interrupt works as expected. It seems it is a compiler related problem? This is strange as I have other programs with interrupts where...

Hi, I have set up an interrupt on GPIO23 on an ESP32-WROOM-32E but it does not get triggered. I have changed to GPIO19 with exactly the same code and it works so I know my code is ok. I have attached a scope to GPIO23 and I see the IO being toggled by the device that generates the interrupt so that´...

I stopped using linear voltage regulators as they are inefficient and can require additional cooling. I now use dc/dc buck converters, type D4012. They don't occupy much space, run cool and so far I've not had any problems with them. As they work to 40VDC input they are ideal for most applications. ...

..just one point, SPIFFS has been deprecated, you should use LittleFS instead.

Have you monitored what is coming out on the device serial port? It sounds like the device is going into boot loader mode - of which there are several. Seeing what comes out on the serial port will let you see if this is what's happening. I've experienced this happening very occasionally with a ESP3...

Hi, any opinions on whether it is better to use a task scheduler or RTOS tasks on a dual core ESP32? I'm thinking of a task that, for example, sends an update every 30 seconds. I've tried both and both work. It 'feels' like the RTOS way is better but are there any opinions? Also, what difference is ...

I just received my ESP-C3-12F boards (not KIT boards, the 'raw' board) that are (nearly) pin compatible with the ESP12F. After assembling my board I found I couldn't program it via my USB -> RS232 adaptor using RX/TX (as I had always programmed my ESP8266 devices. The serial port worked fine. Read t...
