I am writing a device driver for printers and need ring buffers for printer responses. I wonder if there is one that handles buffering read of UART etc or the buffer is built into the UART code. I've not read the code yet. I just read Arduino's HardwareSerial.cpp for an idea but their code has the ring buffer mixed with the hardware serial code so it's not independent nor is it reusable. A quick internet search turned up a few git repos and none of which has nearly long enough history and forks to give me confidence in.

Thanks!

Great! Thank you! That was very speedy response. How do you read all the IDF references? It's so long I wish I could take a break and just read the references for a month
