You're replying to a 4-year old thread; I was talking about the 'original' ESP32 (no -S or -C suffix). I think it's indeed supported again on later chips. I guess we didn't bother to implement it in the ULP toolchain yet, though. Oof, my mistake :( I'm assuming there's no other way to read the temp...

I've tried using this instruction as I was under the impression that it still worked, as per the latest datasheet: ESP32-S3 https://www.espressif.com/sites/default/files/documentation/esp32-s3_technical_reference_manual_en.pdf on page 317 and ESP32-S2 https://www.espressif.com/sites/default/files/do...

我已在英文讨论版发了这个问题，但是没有什么回答。对不起我的中文不太好 QWQ：https://esp32.com/viewtopic.php?f=41&t=39217

开发环境：使用IDF-5.1.1，芯片为esp32s2
我使用的是ULP-FSM 协处理器和ESP Rainmaker。

我现在的问题是芯片进入了Deep-sleep 模式，过了几段电源循环（差不多十秒后）就没有任何反应了。请问下大家有经过这种问题吗，使用ULP-FSM 协处理器和ESP Rainmaker？

对这个问题有什么建议都好，多谢。

Hello all, I am currently working on a project where the esp32 works like an adaptive sensors, sensing data in deep-sleep and uploading data through the RainMaker in active mode at 4 second intervals. I'm having an issue where upon entering deep-sleep the ulp timer cannot wake-up the main processor ...

Upon reading on the ESP Insights, it has come to my attention that this is because data is stored in the RTC memory. My code for the ULP is also stored here, hence the error.

Hello all, I have an issue with enabling the ESP-Rainmaker insights. I currently work with the ESP-IDF on the ESP32S2 and am using it with the ULP ADC sensors for a project. Upon enabling insights in menuconfig (component config->ESP Insights->Enable ESP Insights), the project can no longer flash du...

According to https://docs.espressif.com/projects/esp-idf/en/v5.2.1/esp32s2/api-reference/system/ulp_instruction_set.html#st-store-data-to-the-memory ST does: Mem[Rdst + offset / 4]{31:0} = {PC[10:0], 3'b0, Rdst, Rsrc[15:0]} where 'offset' can be a (signed) 13-bit value - coincidentally just enough ...

st r0, r3, sample_counter Note that the 3rd argument to the ST instruction must be a constant. The assembler takes the 'address' of the label 'sample_counter' as the constant value. Maybe try something like this: move r3, sample_counter ld r3, r3, 0 // load sample counter value into r3 st r0, r3, a...

By which value do you increment the sample_counter? I think you need to increment it by 4. The third argument of the ST command is a number of bytes, not words. See https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/ulp_instruction_set.html#ulp-fsm-addressing I've set ...

This code is based off the existing adc threshold example for the ESP32S2 (https://github.com/espressif/esp-idf/tree/58283e385a7cbd04b8f628af15b5acf633aac2f3/examples/system/ulp_fsm/ulp_adc). I need to store ADC values into an array in the ULP FSM mode so that the chip can undergo multiple deep-slee...
