PC MCAL-CAN over JSON-RPC (Simulate CAN)
This example shows how a C PC implementation of AUTOSAR MCAL CAN talks to EcuBus-Pro Simulate CAN through JSON-RPC.
Start a project that contains Simulate-0 (GUI start, or ecb_cli seq / ecb_cli test). EcuBus then listens on 127.0.0.1:17320. Your Can.c must open free handles (1, 2, …). It cannot reopen Simulate-0. Frames from Can.c appear as RX on the Simulate-0 trace.
Your production Can.c should keep the AUTOSAR signatures (Can_Init, Can_Write, Can_MainFunction_Read, …) and implement each of them as one JSON-RPC call. can_rpc_demo.c inits Simulate-1 and Simulate-2.
Run
Terminal 1: start EcuBus with a Simulate-0 device (GUI or CLI seq/test).
Terminal 2:
cd resources/examples/mcal_can_rpc
make
./can_rpc_demo
# or: ./can_rpc_demo 127.0.0.1 17320You should see Can.Init for handles 1 and 2, Can.SetControllerMode, Can.Write on handle 1, then Can.MainFunction_Read returning the loopback frame on handle 2.
