Well, still digging...I'd be highly impressed if the "magic of AI" can piece things together like this... First was to search the entire Github ESP-IDF repository for "Brownout", and start digging through the search results... From https://github.com/espressif/esp-idf/blob/master/docs/en/api-guides/...

This may sound a bit strange (but I'm known to "misuse" things all the time): I need to programmatically change the brown-out detector's setpoint from the application firmware. In short: I have a short-term power backup system from a 3.0v ultracapacitor, followed by a boost converter. (The ESP32-S2 ...

The way you are doing this now seems to be the correct one. I don't think there is any better option when using just COMPONENT_EMBED_FILES without any extra logic. (extra logic would be: determine size of the file at Make run time, store it as a variable, add -DMY_FILE_LEN=$(length_var) to CPPFLAGS...

+1, thanks for the valuable input and topic. From the ESP32-WROOM-E datasheet https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32e_esp32-wroom-32ue_datasheet_en.pdf , page 10, note pins 17-22: https://i.postimg.cc/Y0VstRbm/ESP32-E-pinout.png Confirming the above, that the I/O ...

Hello all, I have a problem that's kind of got me stumped. Basically, I've designed a PCB around an ESP32 that provides WiFi connectivity and access to a large power supply. It communicates with the power supply's CPU via RS-232 (connector, not on the same board.) Most of the time it works perfectly...

I've been doing some tests on this lately, and have come up with the following (non-official) conclusions. Basically, I'm testing with a 1K resistor from 6.4v to an ESP-WROOM-32 on a Devkit module that is powered via USB and running with all I/Os at default states. Only some of the I/O pins appear t...

So I can report back that I have successfully programmed and encrypted 18 ESP32 project boards using Arduino IDE 1.8.11 with a custom bootloader. Basically, I GIT'ted ESP-IDF v3.3.1, configured the bootloader as desired (encrypt on start, disable plaintext flashing, release mode, QIO, 80MHz, 4MB), t...

The fact it logs here may be because there's no factory partition, I'm not sure - what IDF bootloader version are you using here? Well, that's just the problem. After spending multiple hours beating my head against the wall with ESP-IDF this morning, here's the answer: I have absolutely no idea. Un...

My apologies in advance if this is posted in the wrong forum--but searching the forum is extremely difficult for me. After about two searches (which can take 10 seconds to return), the ESP32 website starts returning a completely blank page. Not sure what's going on--I'm usually better off searching ...
