Update… got the little bugger to talk (need to cycle chip select every byte in and out).
Now I know why you guys are called Sparkfun. Tried to change to 128 microstepping and zaporama on what appears to be the bootstrap cap. Sparks a flying and one L6470 is toast.
Good thing I bought 6.
By the way, setting parameters on this guy is very tricky, even with the ST Evaluation software.
OK. I give up. I can not get comm working with this chip. Does anyone who has got it to work have any clues as to why the @#$%* thing sits there as mute as a mummy? I have interfaced a lot of SPI chips with no where near this level of trouble.
No public wish lists :(
