UART options not working about espruino HOT 3 CLOSED

Ok, just added 7 bit support via software. If you use one of the latest cutting edge builds I think this should be fixed.

It should all be fine apart from 8O1 which will now error, as this can't be done with the chip's hardware

Hi,

Sorry for the delay - I've just looked into this, and unfortunately the actual UART hardware on the nRF52832 chip doesn't support 7 bit or non-even parity: https://infocenter.nordicsemi.com/pdf/nRF52832_PS_v1.4.pdf

I'm wondering what the best way of handling this is... 7 bit + parity is effectively transmitted/received the same as 8 bit without parity, so I guess we could detect if 7 bit is specified and if so could mask of the received data to 7 bits - parity wouldn't be checked but at least you'd get the right data.

Do you need to be able to send data as well? If so then we'd have to calculate the parity bit inside Espruino and then set the top bit of the data we send to that, but it could work...

PS: I also randomly get serial readings when I power the Puck.js with a CR2032 battery

Have you got ground connected as well as serial RX/TX? If not then that could explain the bad readings?

Thanks! It works now :)
