Re: ESP32-S2 ULP

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.

Re: Truly ultra low power EPS32 module?

I have several ESP32-based battery-driven sensors working. In the ESP32-world the board is the main factor. Like NickAllen wrote, the DFRobot boards and some Lolin boards are good for that, I use the Lolin D32 (not "Pro") board. A new DFRobot board with the ESP32-C6 looks good: https://wiki.dfrobot....

Re: Wemos D1: Unable to use RX/TX pins (for hardware serial)

How do you connect serial to the PC?
Have you connected RX to TX in both directions?

Re: Unable to toggle esp32 c6 GPIO_NUM_4

Which board are you using? Do you have a schematic?
Perhaps there is something connected to GPIO4 onboard.

Re: esp32 WiFi does not work with battery power

And the LDO should provide at least 500 mA of maximum current.

Re: GPIO isr is not working

Thank you, "Ctrl-T and X" is working for me. The reason why "Ctrl+AltGr+9" is working for me and not for Henry: I'm using Linux for the development environment, not Windows. So it's a different keyboard driver implementation. Perhaps the "Ctrl-T and then X" workaround should be mentioned in the docu...

Re: GPIO isr is not working

Hint: On a German keyboard you can abort the idf-monitor with STRG-AltGr-9.
AltGr-9 is the combination for "]", "STRG" is "CTRL".

Re: LP Core on ESP32-C6

I think the C6 LP CORE is different to the ULP-RISC-V CPU used in S2 and S3. The API is different and also the implemented RISC-V-Features. I asked some questions about the C6 LP CORE last week: viewtopic.php?f=13&t=37705

I think the API is still under progress.

ESP32-C6 LP CORE

I did some tests on the ESP32-C6 and now I'm programming the LP CPU. I managed to run the GPIO and I2C examples and wrote a driver for an AHT20 I2C temperature / humidity sensor. One use case for me is the LP CPU checking sensor data with some basic processing while the main CPU is in deep sleep mod...

Re: Daylight Saving Time and ESP32

According to "https://github.com/nayarsystems/posix_tz_db/blob/master/zones.csv" , I get America/New_York "EST5EDT,M3.2.0,M11.1.0" instead of: "EST5EDT,M3.2.0/2,M11.1.0" in your example. What is the "/2" for in "M3.2.0/2" ? It's the time when the change occurs: The time fields specify when, in the ...
