HE351VE turbo CAN broadcast in pre-1.5 alpha 4

[fpvmustang]

I can not get he351ve can bus working changed baud rate to 250 changed boost to open loop so boost duty sent out of boost
tried broadcast interval 150, 50 and 70 ms
what's a good free can bus sniffer for arduino?

Glad you've tried it, but unfortunate that it isn't working yet.

I'd certainly like to know what's different about the data. If the baud rate is ok, then perhaps an error in the packet.

It would be worth starting a new topic for this - I'll split this one.

The current code looks like this:

Code: Select all

    /* Typically the turbo wants 250k baud. (Ford application 500k?) */
    if (ram5.can_bcast2 & CAN_BCAST2_HE351) {
        unsigned int bv;
        /* holset HE351VE VGT turbo and a wastegate
        29bit CAN message 0x0cffc600
        8 bytes
        D0, D1  = 16 bit little endian value 0-1000 for position
        D1 = 0x02
        D2 = 0x01
        D3 = 0xff
        D4 = 0xff
        D5 = 0xff
        D6 = 0xff
        D7 = 0xff
        ----------------------
        */
        bv = outpc.boostduty * 10; /* convert 0-100 to 0-1000 */
        data[0] = bv & 0xff;
        data[1] = bv >> 8;
        data[2] = 0x01;
        data[3] = 0xff;
        data[4] = 0xff;
        data[5] = 0xff;
        data[6] = 0xff;
        data[7] = 0xff;
        send_can29bit(0x0cffc600, data, 8);
    }

i'll try to compare the can bus signals this weekend

[fpvmustang]

having problems sniffing the can bus but have help coming.
