Re: When we will see first ESP32-S2 boards ?
Maybe the product picture is old but they all look like S2-beta models.
I expected some boards with camera and lcd fpc interface connectors.
Too bad the clock speeds didn't get bit higher too

When we will see first ESP32-S2 boards ?
The new chip is out and people are excited to see first dev boards and how they perform.
How soon you think we can see and buy the new S2 products?

Re: Question about Python version used in IDF
Thanks Krzysiek!
I didn't even notice Python 3 works with idf already)
I was able to flash esp8285 with idf.py installed from esp32 toolchain using old Python 2.7

Question about Python version used in IDF
So I updated recently some repositories - actually ESP8266_RTOS_SDK which got very nice CMake support and runs awesome. However I got many errors before I managed to update all required packages - errors were saying Python2.7 is end of life. All packages loaded fine but I had to explicitly run Pytho...

Re: Synchronizing SPIs
SPI is a serial exchange protocol which means that each bit of a value being sent is presented to the MOSI (for a master - MISO for a slave device) pin in line with the SCK transitions. Therefore I have no idea how this relates to the gpio_matrix_out function. Yes but normally all bits go through o...

Re: Porting esptool.py to C
I tried once porting it to C# which would be much smoother but got stuck on SLIP protocol and stopped project.

Re: Synchronizing SPIs
Thanks Susan. It is complicated, I'm trying to synchronize 2 or more devices that should read data at exact time.
I will look for more solutions I think.
Looks like gpio_matrix_out can map bits 4-7 of SPI data byte to individual pins which may help if it works

Synchronizing SPIs
I would like to send signals from all SPIs at exact time so I know when all transmissions end at same time Are they synchronized by default or must be configured? I also noticed there are special functions for SPI pins as output: (gpio_sig_map.h) #define SPID4_IN_IDX 128 #define SPID4_OUT_IDX 128 #d...

Re: Standalone SDK

So you are saying non-OS SDK for ESP8266 is actually a minimal RTOS ?
