Good time of day,
I’ve got the wiz550io (Ver1.0) and get wrong results when reading VERSIONR, RTR and RCR:
VERSIONR --> 0x28 (instead of 0x04)
RTR --> 0x1CAB (instead of 0x07D0)
RCR --> 0xAB (instead of 0x08)
Since this is my first SPI implementation I’m pretty sure I’m doing something wrong.
Would somebody please take a look at the attached images from the logic analyzer and give me a hint what’s wrong?
(The timings are on the top of the image)
These are the logic analyzer settings:
- MSB first
- 8 Bit per Transfer
- CPOL = 0
- CPHA = 0
- EN is active low
