Re: Unable to get SIO card working


 

Hi Morgan,?

I haven't actually measured the current draw on my boards, but 200mA was a guess at the most it should use.? I think 70mA is good enough.

If you put a scope on the UART output and power CPU + SIO board, do you get any output?
Scope the UART CS, is it getting addressed?

Hello Josh,

I think I connected my multimeter correctly, I put it between the FTDI cable and the terminal on the side, and I ended up measuring ~70mA with the SIO and CPU cards. I tried out the other combinations and got 80mA with the Front Panel connected and 56mA with all cards connected.

Unless I made a mistake connecting it looks like its low instead of high. I did find out however that if I have the Front Panel connected and I hit the reset buttons (F and 0) on there the SD card LEDs will flash. So that's something at least.

Thanks,
Morgan
