Some insight into what I've done/tried so far (for ECAN): -Physical layer is correct scope shows nice pattern for both Tx and Rx at the right voltage levels -Messages send from my CAN box (Anagate CAN duo) do NOT get Acked as shown by the Anagate interface. The same seems to be happening with the C1BUFPNTn SFRs, I wrote BUFPNT 1, 2 and 3 to 0xFFFF (FiFo) but the SFR map does not show any value for those registers. So far I've been trying to narrow down the reasons as to why it isn't working, and ran into this issue. So, can someone shed some light on what is happening here? I've been trying to get ECAN to work for over a week now (see my previous post) and so far to no avail. As expected from the window functionality (WIN bit) the C1TRnmCON registers show 0x0 when WIN=1, and 'revert' back to the configured values when WIN=0. The WIN bit in C1CTRL1 is set to 1, enabling access to the filter/buffer registers. Hello While trying to get ECAN to work on the mentioned chip, I noticed something strange: AFTER writing C1RXF0SID and C1RXM0SID, both registers show no value. ![]() DsPIC33E(256MC506) SFR with no address and no value.?
