I have a MindStorms project idea that requires the robot to "display"
something, rather than run a motor.
An alphanumeric displaying words would be awesome, but a two digit number
would work.
Looking at NQC manual, I found:
SelectDisplay()
DISPLAY_WATCH, DISPLAY_SENSOR_1, DISPLAY_SENSOR_2, DISPLAY_SENSOR_3,
DISPLAY_OUT_A, DISPLAY_OUT_B, DISPLAY_OUT_C
Is there anyway, I can display a variable?! DISPLAY_VAR? Please Dave?
Thanks in advance to all who replies.
PS: I have several mechanical display ideas, but it would be a lot cleaner
to display it on the RCX LCD.
