Re: Initialize custom pins for SPI

Fyi Arduino also uses ESP-IDF (and thus FreeRTOS) underneath. Having an OS/RTOS is pretty much a requirement if you want to do multi-core programming with complex stuff like WiFi and BT. Well, then you easily should be able to help me. Where all pin initialization is located so I could assign pins?...

Re: Initialize custom pins for SPI

This is response I received from Arduino forum
On the Arduinos, the pins are given special meaning, like SPI, I2C, etc. by the chip maker.

IF the ESP allows customizing the SPI, I2C, etc. pins, you should ask on the ESP forum how to do that.

Same question here.... (Not about Visual GDB - not free)

Re: Esp32 Wroom and CCS811 in deep sleep

That is very helpful - all data must be in rtc memory or it will be erased after wake up
I am reading about sleep modes

Re: Initialize custom pins for SPI

I care less if I use Arduino. I just want to initialize custom pins using esspresif idf or other code Also I have some questions about asp idf. I assume sdk is to use with FreeRTOS and has nothing to do with Arduino esp libraries. I don't even know how different is the architecture of those. Some pe...

Re: Initialize custom pins for SPI

So is it possible to do that? how do I attach custom pins to spi clock mosi miso and other interfaces?

Re: Best NTP-Time library for ESP32?

I think you have to find other way to wake up from sleep. Processor must not restart or it is simply not a deep sleep but soft restart. If they call such restart a deep sleep - that is just ridiculous. There must be other way Here is more information about sleep modes https://esp-idf.readthedocs.io/...

Re: Best NTP-Time library for ESP32?

I would study datasheet. I think I saw some information pertaining to deep sleep that only certain level of interrupt can wake the device up. Or maybe it is some kind of external event signal - hopefully can be periodic. I know hardware timers should be able to completely wake system up

Re: Initialize custom pins for SPI

Well I am not sure what other choices I have. I really would like to use plain non-Arduino libraries but I am just a beginner in esp programming. I don't have much choice but use Arduino framework for some time unless you can direct me to better dedicated framework - I prefer under Windows only. STM...

Re: Best NTP-Time library for ESP32?

I just looked at \arduino-esp32-master\tools\sdk\include\lwip\apps\sntp
Seems like there is a dedicated code for sntp and configTime so no need to recreate ntp I guess.
If you drill down into esp-hal you can merge more features
Let us know how it works
