Dear Christian Walther, It is so much grateful for me to have your reply again. I think I am understanding "WRITE_RTC_REG", thanks to Christian. As you said the ESP32 technical reference manual is so helpful for to understand ULP. I am using ESP32-PICO-V3-02, so I've download " https://www.espressif...

I wish I could get my head around accessing the ULP from micropython! I found https://github.com/ThomasWaldmann/py-esp32-ulp/blob/master/examples/counter.py but it crashes because there is no esp32_ulp on my machine. I found a lib of the same name @ https://github.com/ThomasWaldmann/py-esp32-ulp/tr...

I don’t think SENS_I2C_SLAVE_ADDR0 is the register’s address, that looks more like a mask. Correlating esp32_technical_reference_manual_en.pdf section 30.8.1 to the stuff in the headers, try # from soc/soc.h #define DR_REG_SENS_BASE 0x3ff48800 # from soc/sens_reg.h #define SENS_SAR_SLAVE_ADDR1_REG ...

Greetings! Thanks for the great micropython, v1.18 is awesome for speed :) I am trying to understand how to manage the obscure ULP code, I found https://github.com/ThomasWaldmann/py-esp32-ulp , Thanks to Thomas, I've done a few things with that. It has some limitations(exclude .macro etc), but almos...

I think your ESP32 does not have PSRAM, and
flashed wrong type of firmware(GENERIC_SPIRAM)
Try the firmware, BOARD=GENERIC compile option, and flash it.

Great thanks to Thomas, I saw the PR on lvgl repo. I am so happy to find it. SD card works great , at the same time the display works. My devices are, LOLIN D32 pro with builtin SD card slot. with GC9A01 display(no touch module) Is there any performance difference between half_dulplex and full duple...
