Re: ULP WakeUP
Well for my part I would just really be happy, if someone could update the windows binaries on github. Getting the toolchain to compile is a pain. I guess I will have to switch to a Linux VM soon

Re: ULP WakeUP
Ah Ok there seem to be a new version of the ulp toolchain on github. The windows build is just still not updated so I have to build it my own.

Re: ULP WakeUP
Well something seems to be odd about jumping using a register. I played around with it and it just doesn't work. Whatever is happening the program doesn't jump to the right position The sad part about it that this means I also can't use tomtors Stack macros. In general it's impossible to implement a...

Re: ULP WakeUP
Well I will test it a little bit more. I am still more confused why the main CPU doesn't wake up when I use the label and not the register.
It's not that important. But I just started a bigger project and I wanted to understand whats actually going on here.

Re: ULP WakeUP
Yes. Jump and then an immediate value. This should work. Shouldn't it?

ULP WakeUP
Playing around with the wake instruction of the ULP I found some strange behaviour. Maybe someone can explain. So I came across this testing the I2C code from tomtor: https://github.com/tomtor/ulp-i2c/blob/master/main/ulp/main.S The critical part is the disabling of the ULP Wakup Timer with: WRITE_R...

Re: ULP-I2C
Wow thank you very much. I allready had the idea that this must be possible somehow in a way like this. I didn't had time for a detailed look into it, but I'll play around with your code soon. I actually didn't expect a working code example and I really appreciate the extra effort. Well time to work...

ULP-I2C
Hi! I just started with the esp32. I wanted to use an extern 16-bit ADC with the ESP. And I also intended to read that ADC with the ULP. As the ULP supports I2C I thought it was no problem. Now I studied the Technical Reference Manuell and read about the RTC_I2C Controller. Apparently the I2C interf...
