Re: Docker: Super easy compiling and flashing without installing the SDK and all the dependencies

I don't know the difference between those 2. I will be great if the Espressif guys that uploaded these containers also publish the source code of what is inside.

My project make usage of ULP functionality and I don't know if any docker container published in dockerhub will work for me. Any idea?

I2C use by ULP and CPU

Hello, I'm trying to use the same pins for I2C in ULP and CPU (active mode) but when I try to use it, nothing works. Is it possible to have both configured to use the same pins or should I use different ones? I'm using SDA pin as the 33 and SCL as the 32. Also I tested both in separated programs and...

Re: ULP uart send/receive

UART is not supported by ULP, only ADC and I2C.

ULP with JTAG?

Hello, I have the ESP-Wrover-kit and I would like to debug some assembly code using JTAG but I'm having a hard time to make it to work. Seems like the OpenOCD or JTAG doesn't like that the ESP32 go to sleep so my question is: is it really possible to debug an ULP assembly code using the JTAG? Regard...

Re: ULP wake using ext1

Thanks for the clarification, I believe you should add this information in the ESP32 documentation, is not there and is not that obvious to think it can't.

ULP wake using ext1

Hello, I would like to know if is possible to wake up ULP by using any RTC gpio with a HW interrupt while ULP is sleeping. Until now, I'm able to wake up the CPU using "esp_sleep_enable_ext1_wakeup" but I'm not sure if is possible to avoid waking up the CPU and go directly to ULP. If it's possible, ...
