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...

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

Re: Standalone SDK
I understand the re-architecturing problem for non-OS SDK, however looking at ESP8266 it is possible and works good. Intercommunication sometimes is not crucial in many performance projects and also having bare metal execution gives more management control over memory and the way the whole system be...

Standalone SDK
I know current IDF supports FreeRTOS but maybe in the future it would be also good to have a standalone SDK for ESP32?
Do you think it is possible and have you consider such development?
Thanks!

Can you give us some more details?ESP_Sprite wrote: ↑Mon Jan 06, 2020 10:25 amNothing I can make public that's more than 'we're working on it', sorry.

Re: What would you like to see in The Next Chip?
I would still consider Risc-V /64bit - why not - architecture is perfect for ESP64 )
Going with ARM increases costs unfortunately ...
