Retrocade Schematic

Recommended Posts

Hi Jack,

think I have found a problem in the Retrocade schematic. It's ADC related.

 

The pin names for the SPI controls on ADC1 and ADC2 are reversed. For example, SPI ADC1 is connected to 4 controls, all identified as 'ADC2_*'. Ditto for ADC2.

 

Schematic elements SPI ADC1 and SPI ADC2 are consistent with the PCB silkscreen, it is the signals that are mixed up.

 

The problem is also carried through to the UCF file. Pins for ADC1 are in fact controlling ADC2.

 

Regards,

Steve
