Hi,
I tested everything following the schematics and everything seems to work fine, all voltages are correct, at least the ones described (+3.3 V +5 V-)
and each IC is in the correct direction.
Also tested resistance, ok.
About the computer I use Mac but I don't believe the problem is on the driver.
The thing I need to understand is why even without plug the DIN the led2 of the LPC remains continuously red, I think this is a clear sign that the problem lies in the core of the LPC but where?
Thank you.
Regards.
