Hi!
I created a Software Serial driver for Chibios HAL, in case anyone is in need.
It is in my Fork on Github, there is a README.md file with instructions.
Fork: https://github.com/0x3333/chibios_svn_mirror/
Driver Location: https://github.com/0x3333/chibios_svn_m ... oft_serial
Driver Readme: https://github.com/0x3333/chibios_svn_m ... /README.md
