I like to use Machine -> "Show Hal Configuration", which lets you see and set any pin, and watch pins or signals. More convenient than halmeters in my opinion. Halscope has a bit of a learning curve. -- Ralph From: jeremy youngs [jcyoung...@gmail.com] Sen

Halmeter has blanked fields and inoperable buttons, so I cannot select pins. Halscope shows no active threads. So I cannot continue as the Hal tutorial shows. nothread.jpg ---

Pin 1 and 3 are my a and b from the 7i42. I have verified encoder is operational and 4.56 volts at pins 1&2 on 7i42 so all seems good there. I'm pretty sure this is a syntax problem . Input ? hal.jpg ---
