Hi, I would like to use assembler to control the leds on the led expansion card. In basic its easy using the out command but I am wondering how to use assembler. Any suggestions would be good.

Assembler still uses the OUT command.

OUT port: Output data from Accumulator to port.

load the number into the accumulator then do OUT portnumber to display the number in binary on the expansion module. Simple!
