Re: [Q] ESP-iDF Versions ESP32-S2 beta ./. ESP32-S2 release

Hi Rudi, To answer the toolchain related question: IDF version v4.1 (which is currently in development as v4.1-dev, but will soon become a release branch release/v4.1) will indeed support ESP32-S2-beta, not the final ESP32-S2. In recent versions of IDF, for users of the CMake build system, we recomm...

Re: Timer groups documentation

Yes, GPIO.outX_w1ts.data and GPIO.outX_w1tc.data are safe to use from an ISR. But what about timer priorities and levels? Are there such things? Interrupts can be assigned to one of a few levels (1, 2, 3). There are also high-level interrupts (levels 4 and above), but ISRs for these are typically wr...

Re: esp-idf-tools-setup-2.2.exe Installation has failed with exit code 1

Was the Python 3.7 installed using python.org installer, or as a Windows Store app? We have tested the installer with python.org distributions, but I think we haven't checked how it behaves with the Windows Store app, yet.

Re: Random crashes in tx_pwctrl_init (backoff_en=<optimized out>) at phy_chip_v7_cal.c:2192

A crash during PHY calibration is usually an indication of a power supply issue. Please check if you have the brownout detector enabled in menuconfig, and check the waveform on the power supply line when the app starts up. If you see that there is a glitch in VDD when Wi-Fi starts up, you may need t...

Re: Timer groups documentation

This does not indicate there is a conflict with some other module using the same timer. In fact, Timer group timers are not used by other resources in ESP-IDF (such as Wi-Fi). The issue may be related with the fact that you are designating an interrupt as being placed into IRAM, but then calling a f...

Re: esp-idf-tools-setup-2.2.exe Installation has failed with exit code 1

It looks like you may be trying to use the new tools installer with IDF v3.2? For v3.2, the getting started guide for Windows is here: https://docs.espressif.com/projects/esp-idf/en/v3.2.3/get-started/windows-setup.html. It involves using an MSYS based environment. Do you need to use specifically ID...

Re: HULP - ULP Helper

Very neat library @boarchuz — going to be very useful for lots of projects!

May I suggest dropping a CMakeLists.txt file into the root directory of the repository? This way the repository would be a valid esp-idf component, and could easily be included into other projects.

Re: Reading files from SD Card using sdmmc_read_sectors()

There doesn't seem to be a standard way (as in, POSIX) of getting the file allocation table information. FATFS library also doesn't expose any such functions, as far as I can tell. The file structure used by FATFS (called FIL) is public, though, in ff.h (https://github.com/espressif/esp-idf/blob/303...
