Re: PCNT hardware counter crashing

If you are using 'make monitor' to view serial output, you should get a backtrace showing from which function abort was called. If you post complete output from make monitor, someone here may help you figure out what goes wrong.

Re: Are the features of the auto light sleep of esp32 similar to the auto light sleep of esp8266?.

Yes, automatic entry into light sleep will only be possible when no tasks are running, except for the IDLE tasks. If both CPUs are running IDLE tasks, then the system will be able to enter light sleep (provided that WiFi driver is either stopped or in light sleep phase). Note that some drivers which...

Re: Making use of the built in BASIC interpreter

I am tempted to announce a challenge to run some old game written in BASIC, using BASIC interpreter, all from RTC memory. Just worried that we will lose Sprite for a day or two.

Re: Is brownout detection usable now?

Please don't consider the BOD of ESP32 a bullet-proof production grade protection measure. It is mainly provided to help identify problems with inadequate power supplies, which were very common for ESP8266 and are still common with ESP32, sadly. For this purpose, it serves quite well — you get an er...

Re: Making use of the built in BASIC interpreter

Well, technically you can use the interpreter from wake stub: copy it into RAM, un-memfrob it, jump to the entry point.

Re: [Question]: Release of memory passed by reference to ESP-IDF functions

This should probably be mentioned in function documentation, but in the meantime we can start by looking at the code... We see that the pointer to the buffer you pass to BLE functions (such as esp_ble_gatts_add_char ) is stored into a btc_ble_gatts_args_t structure, allocated on the stack. The code ...

Re: Need Help for NTP Configurations for ESP32

jaracil: this is super useful, thank you for sharing. Would you mind to amend Readme mentioning what license is the project distributed under?

Re: Is brownout detection usable now?

Update: indeed the values listed in menuconfig are not correct. Here are the levels measured on one of the chips:

Code: Select all

0   2,40
1   2,46
2   2,56
3   2,59
4   2,60
5   2,65
6   2,70
7   2,74

We'll do some more measurements to check variation between chips.
