Altera PL-APU USB Master Programming Unit (Power supply ratings Help!)

Hi Daixiwen,

Thank you very much for that Tip.

I managed to adjust the voltage and got the APU programmer running perfectly at

7.5 Volts DC (1.0 Amps) center positive.

I had used this setting early on during testing which failed.

It turns out that the power supply I was using at that time was damaged and it was only providing around 400mA or current.

So now with the 1000mA supply, the APU-USB drivers detected the APU hardware perfectly and was able to properly install.

I made this diagram for my archive.

Thanks very much for all the help.

Kind Regards,

Gerry O'Brien
