 | | re:4 line LCDs and other LCD questions
|
| (...) HB experts, correct me if I'm wrong, but if someone wanted to use an LCD bigger than 2x16, wouldn't the pcode have to be recompiled? I know that in the pcode.asm file there is reference to displays up to 2x80 (of which I have 4 and none work (...) (29 years ago, 12-Apr-96, to lugnet.robotics.handyboard)

|
| Does anyone know how to activate the servo on HandyBoard with IC? (I am going to use the Polaroid Sonar Ranger when it gets here.)
