UART

Source

I'm using the UART from the spinalhdl lib (Apb3UartCtrl)

#Specification 115200 8N1 : 115.2 kBaud, 8 data bits, 1 stop bit, no parity, 3.3V example packets: _-_______- payload=1, _-_-___--- payload = 11000101b

Interface

APB3 interface as follows:

Register	Offset	R / W	Name	Description
0	0	W	Send payload	Write payload to be sent
0	0	R	Receive payload	The last received payload
0	16	R	Received valid	1: the received payload is valid 0: received payload not valid
4	24	R	rx fifo occupancy	???
4	16	R	tx occupancy	???
4	15	R	stream valid

ToDo: Add the registers to read / write the configuration
