Hi all,
Untill so far:
-
I have read the ENCX24J600 data sheet
-
I have read the ENCX24J600 feature-runtime-wip code
- The register map of ENCX24J600 for SPI interface is written correct
- The SPI opcodes are correct
- The transmit and receive buffer are configured and initialized correct
- The receive filter is configured correct
- The MACCON1 is configured correct
- Checking the ECON1, ECON2, MACON2 is in progress
