We have trouble to get the SPIRIT1 on our own board working. The very basic problem is that the chip can not be switched to any other state then ready
Therefor the setup for any frequency settings are not possible.
We spend now one week to make sure that the SPI communication is correct and working as required.
Unfortunately is the datasheet very basic e.g. the status bytes responded with the first 16 clock cycles are not documented.
We have the following questions:
Are there other status bytes to read to figure out what the possible problem of our design is?
We have assembled a view boards with different soldering specs. But all behave the same.
