9 General Purpose Output
9.1 Introduction
LEDs consist of red, green and orange-yellow colours. The LEDs are hence software controlled with func-
tions to turn them on/off. A pair of GPOs control one LED. GPO1 and GPO2 control LED1, GPO3 and
GPO4 control LED2 and GPO5 and GPO6 control LED3. The tables below illustrate the relation. “0” is off,
“1” is on. For example to turn the LED 1 to green GPO1 must be turned on and GPO2 must be turned off.

Remembered
This command shifts the strip chart left or right. [ref] determines both
which strip chart is used and which direction it will shift. The direction
is selected by the most significant bit (MSB):
For example if [ref] is 1:
This command shifts the contents of the area defined in the Initialize
Strip Chart command 8 pixels at a time.
