README.md
This is STM32F072 port of jcw's SerPlus:
- https://github.com/jeelabs/embello/tree/master/explore/1649-f103/serplus
- https://jeelabs.org/article/1649f/
- https://github.com/jeelabs/folie
Modifications
- runs on F072, aimed for the bat board, with [SerPlus shield], which has some extra features, so:
- button controlled mode: either “SerPlus mode” or straight “raw UART with DTR”
- WS2812 neopixel status LED
- control on/off output power with a FET
- measure output power level using ADC
- these can be turned off via #defines in the code
In “raw” mode, it works as any other USB-to-serial converter (with DTR), so it can be used to upload firmware to arduino-type boards (tested).
Original Serplus README
SerPlus is an STM32F103-based bridge between USB and a serial port.
Inline telnet escape codes can be used to control DTR, RTS, and parity.
Based on the usart1_irq_printf and usb_cdcacm code from libopencm3-examples (LGPL3).
For the RAM-based version, to be loaded at $20002000, use:
make -f Makefile-ram
