Major improvement/refactoring towards terminal/syntax using tokenline (instead of microrl) thanks to Bert Vermeulen (biot) for that amazing piece of software and all the work on this project.
Also lot of new commands added like ADC, GPIO, more sd commands.
SPI1&2, I2C and UART1&2 are tested with logic analyzer/oscilloscope.
