Re: Hacking the Xaar 128 printhead

Pin 9 is marked as TEST 0, and the discs say "not required for operation, should not be connected".For pin 28 however, marked CLK, you must provide a 1 MHz clock signal to the print head. No PWM, just a 50:50 clock. Hey, yeah sorry I actually meant pin 28, on the arduino uno its assigned ...

Hello guys, for a project at uni I have to control a Xaar 128 printhead with an Arduino Mega. I have read the entire topic, but I'm still a bit lost, because I've never worked with Arduinos before nor I have experience with electronics.. I'm trying to make the printhead work with the code from Print...
