Software reset command

Hi, KRI .

I'm currently looking into this and will get back to you,

Best regards,
Christian

Hi KRI,

Just to clarify, you mentioned you used the command A9 followed by 05. The command for a software reset is A3 followed by 05.

Regards,

David

Hi again,

I've been using A3 as first character all the time, the A9 was just a typo in the mail to you.

After reviewing the my code I still run into some problems, please check the attached trace with my comments.

The delay after last byte of the RESET command is set to 300 µs and the speed on the SPI line is 20 MHz.

Regards,

Göran
