Interesting, might be that the device is unresponsive for a bit after the power up bit is set. Either way, good to hear you got it working.

A nice day to you too :)

Best regards

Hello,

SPI runs on 2MHz thats not the problem. CSN and CS aren't the problem either. Maybe the delay before commands. Even tried both phase options.

Actually i cheated a little, coded it on arduino using library and looked at it with logic analyser at work :D. It works now.

Seems i shouldn't have sent the config command straight of the bat. Coppied this sequence where more things are set before enabling the config register.

Thanks for your comment tho :).

Have a nice day.

What is the speed of the SPI interface, and have you tried both phase options?

Could you try to add some milliseconds of delay after resetting CE and CSN (CE should be low and CSN high), before you run the first command?

Best regards
