I wanted to do something similar but I understand that using an ISR is impossible. @microcontroller, any ideas how to do this using a task? If I use the Arduino IDE, at what priority should the task run? And is there any possibility to make it asynchronous? If I look at esp32-hal-i2c.c I see that: i...

Hi all,
The problem is still present in the latest release of the core. I found a fix here: https://git.thc420.dev/blackbeard420/es ... 6f9e2c2bfc

Will it be solved and when?

Best reagrads, Jeroen

I would like to have an accurate core wake up from deep sleep and an accurate ulp wake up at an exact time. Currently timing is dependent on temperature an crystal accuracy. Also I would like to restart the ulp timer at the start of the ulp program, instead of at calling 'halt', to make restarting t...

I would like to wake up de cpu's by the ULP after exactly 5 minutes, independent off the time the ulp has run (I understand the ulp wake up timer starts again after halt, and when halt is called is dependent on the time the ulp has run), and independent off the time drift of the RTC_SLOW_CLK. Is tha...
