The Ampera is still using the old polling logic. The poling code is within the vehicle_voltampera module itself. The Leaf is using the new centralised polling logic (in vehicle.h and vehicle.c). This is the new recommend way of doing this, as the vehicle.{h,c} code will do the polling for you - all you need to do is setup the appropriate structure. The new structure is: typedef struct { unsigned int moduleid; unsigned int rmoduleid; unsigned char type; unsigned int pid; unsigned int polltime[VEHICLE_POLL_NSTATES]; } vehicle_pid_t; and the following polling types are currently supported: #define VEHICLE_POLL_TYPE_NONE 0x00 #define VEHICLE_POLL_TYPE_OBDIICURRENT 0x01 #define VEHICLE_POLL_TYPE_OBDIIVEHICLE 0x09 #define VEHICLE_POLL_TYPE_OBDIIGROUP 0x21 #define VEHICLE_POLL_TYPE_OBDIIEXTENDED 0x22 The moduleid is the replying module id, the rmoduleid is the id to use for the request.

Hi ,
I am trying to make nissan leaf work with normal cable - on the CARCAN.
I am trying to figure out the polling mechanism and I have trouble understanding what the different parameters in the configurations are.
In the ampera file I can see: rom struct { unsigned int moduleid; unsigned char polltime; unsigned int pid; } vehicle_voltampera_polls[] = { { 0x07E0, 10, 0x000D }, { 0x07E4, 10, 0x4369 }, { 0x07E4, 10, 0x4368 }, { 0x07E4, 10, 0x801f }, { 0x07E4, 10, 0x801e }, { 0x07E4, 10, 0x434f }, { 0x07E4, 10, 0x1c43 }, { 0x07E4, 10, 0x8334 }, { 0x07E1, 100, 0x2487 }, { 0x0000, 0, 0x0000 } };
While in the nissan leaf file I can see the following:
rom vehicle_pid_t vehicle_nissanleaf_polls[] = { { 0x797, 0x79a, VEHICLE_POLL_TYPE_OBDIICURRENT, 0x0d, { 10, 10, 0 } }, // Speed { 0x797, 0x79a, VEHICLE_POLL_TYPE_OBDIIVEHICLE, 0x02, { 10, 10, 0 } }, // VIN { 0, 0, 0x00, 0x00, { 0, 0, 0 } } };
I can kind of guess some of it. I also found an old e-mail from Mark that describes a structure similar to the one in the nissan leaf file, but the leaf has one extra parameter - I think it is the return message can Id.
Any info/advice is appreciated!
