Re: Powering ESP32 with Lithium battery (step up module)
You can supply 3.3V directly to the 3.3V pin bypassing the built-in voltage regulator, but make sure it's not above 3.6v (max allowed voltage according to spec)

compilation of esp-adf - howto
I see esp-adf repository links to some specific version of esp-idf (from 2020). But the installation / getting started instructions mention that ESP-IDF should be installed before getting esp-adf from git. So i'm a bit confused - if you're suposed to install esp-idf, why there's an old version linke...

ESP32 Korvo v1.1 - resources
Hi, i got Korvo V1.1 borard (the round one) but it appears it's not listed in ESP-ADF hardware list. So my question is - why? Is it somehow unrelated/unsupported by ESP-ADF, or maybe it's similar to some other board so that it's almost the same? Looks quite similar to LyraTD MSC in shape, but i'm no...

Re: Using timers and interrupts - AC dimmer application
some hints 1. zero detection - check for noise / oscillations and debounce if necessary. I dont know why but my zero detection circuit generated a lot of oscillations at each zero transition and this led to lots of WTF moments. So just count them - should be equal to 2 x mains frequency. 2. RTOS tim...

Re: xTimer...FromISR functions availability - FreeRTOS
thanks, this may come handy in future. The wealth of RTOS functions related to synchronization and message passing can be confusing. And you know what i use for 'deferred interrupt handling' in Arduino? A boolean flag that is set in the ISR and periodically checked in the main loop (logic so trivial...

Re: xTimer...FromISR functions availability - FreeRTOS
Allright, so lets try to get something from that 1. xTimerPend.... functions are there, i just needed to include "freertos/timers.h" in addition to "freertos/task.h". Browsing esp-idf sources helps. 2. But my intuition about them was wrong. xTimerPendFunctionCall will do what it says, namely it will...

Re: xTimer...FromISR functions availability - FreeRTOS
sorry, everything is allright. I'm just suffering from bouts of stupidity. All functions are in place, my code was just messy. please delete whole topic, its useless.

Re: xTimer...FromISR functions availability - FreeRTOS
need some clarification here in the components\freertos\xtensa\include\freertos\FreeRTOSConfig.h file there is this definition #define INCLUDE_xTimerPendFunctionCall 1 this #define controls availabilit of some xTimer.... APIs, not only xTimerPendFunctionCall. and still, xTimerPendFunctionCall is not...

Re: GPIO input interruption is very sensitive
are you calling gpio_isr_handler_add in a loop? what is the reason for that?

xTimer...FromISR functions availability - FreeRTOS
Hi, there's a group of xTimer... functions defined in FreeRTOS that can be called from an ISR: xTimerStartFromISR xTimerPendFunctionCallFromISR but it appears they're not included in ESP-IDF version of FreeRTOS. Not included at all, or can be enabled by some configuration settings? The reason for as...
