Using the YASSD
10/15/2017 at 07:40 • 0 comments

The YASSD is controlled via a UART connection, via a couple of simple commands, at a baudrate of 19200:
To control what is displayed:

ID,NUMBER\n
So if the display has an ID of 04 and you want to display 1337:
04,1337\n
A dot is no problem, just insert it whereever:
04,1.234\n or 04,123.4\n
To change the brightness:
ID,Bx, with x being 0 to F (hexadecimal 0-15) for the brightness, 0 being the lowest, F the highest, for example:
04,B2\n or 04,BA\n
As long as YASSD boards have a different ID set by the solder jumbers, they can be connected to the same UART bus, a bit like how I2C works.
