Yep, that's exactly how it works. If you need different offsets or sizes for the CRCs you can specify the protocol twice, once for the read settings and once for the write settings. |

How does COSMOS check CRCs on incoming packets? We are trying to figure out how to implement CRCs in telemetry packets coming from our target software and are unsure how COSMOS will know where to find the CRCs.
Looking at the documentation for the CRC protocol, I'd assume we just specify were the CRC is in the packet using the bit-offset parameter. So, if we were to specify a bit offset of -16 for a 16 bit CRC, would that mean that COSMOS will look at the last 16 bits of an incoming packet to find and verify the CRC? I assume for outgoing packets, the CRC would also be the last 16 bits of the command packet, right?
