Board 3 MSA CB SPI (RAS PI) status

Post by spyker49 » Sun Jun 09, 2013 9:33 am

Hello Group

Board 3 MSA CB SPI (RAS PI) is operational!

I am using Board 1 (for DC power only)coupled to board 2 fitted with an ATMEL CPU as the SPI test generator plus a custom cable to board 3.

This set up emulates the RAS PI GPIO SPI interface. Each of the 32 SMA CB outputs are set/cleared in turn and it all looks good.

The signals are all very clean with no noise or bounce using a 400 MHz scope. Len
