I have a problem with the output of my kit. Initially the kit did work correctly, now every digital output is 0.6/0.7v. I tried to change IC4 with IC2 but the output not change. None output work correctly.
How I can fix it?
Sorry for my bad english!
Hi,
The digital outputs on the K8055 are open collector.
The voltages you are seeing are normal.
Please see page 19 of the manual (download) for examples (link below)
