Re: FreeRTOS Task Aware Debugger?

How far away are we from seeing this? I really want to stop using Eclipse and switch to VS Code.

Also, if you want a beta tester I'm happy to help.

Re: SPI Master Slave handshake with spi_device_queue_trans

From the SPI Slave documentation: The ESP32 DMA hardware has a limit to the number of bytes sent by a Host and received by a Device. The transaction length must be longer than 8 bytes and a multiple of 4 bytes; otherwise, the SPI h...

Re: IDF and ESPTOOL_PY Licence Clarification Request

We are looking at developing a method of programming the ESP32 from another microcontroller (STM32) using a C application which runs on the STM32. The basic flow would be: C# app on PC / Mac / Linux reads a binary image and send down serial line to STM32 STM32 takes the image, validates it and then ...
