Serial UART Communication

Hello Gordon,

I have a few questions regarding serial communication.

Serial1.setup is not working with parity 'none'. I got the following error:

Serial1.setup(9600,{rx:B07,tx:B06,bytesi­ze:8,parity:'none',stopbits:1});
INTERNAL ERROR: Unsupported serial parity mode.

'even' works:

Serial1.setup(9600,{rx:B07,tx:B06,bytesi­ze:8,parity:'even',stopbits:1});
=undefined

Is null also 'none' ?

Second question. I'm a bit confused about the UART/USART pins. What is the difference between UART and USART ?

On the pinout reference for example "USART1 TX" is labeled on pin B06 and A09.
Thus this mean, that i can choose which pin i would like to use ?

Many thanks
