If you cannot find a stable library for the MCP2551 transceiver specifically, many users simulate the alone using Proteus’s built-in Virtual Terminal or SPI Debugger to verify data transmission, as the transceiver's primary job is physical layer conversion (voltage levels) which is often not critical for logic-level code testing.
