huntik17on Heatshrink: Data compression library for embedded/real-time systems

I ported a tool 'detools' which generates binary patches and compresses them using heatshrink to ESP32 and got some great results! Use case: Compressed Delta OTA Updates for ESP32

ESP32 port: https://github.com/ESP32-Musings/esp32_compressed_delta_ota_...

Nice project! Could you please list the supported micro-controllers and some examples?

You can automate that using flipflops or maybe MOSFETs.

This project is a part of a commercial usage, where the entire product was located remotely, thus it was not possible to manually flash the STM everytime.

Sorry, for going a little off topic here but the same implementation was also done for AVR MCUs (include the famous Arduino UNO & MEGA). Feel free to check it out here -
