test-setup

I used a setup on a stm32 to simulate the accelerator pedal.

stm32f103c6-canbus

This microcontroller sends values to the CANBUS, which can be picked up by the dice software.

In the dice diagnostic software this parameter can be display graphically. (graph)

frame.id = 0x00222222; //pretend this is the CEM module
frame.extended_id = true; //volvo uses 29bit
frame.rtr = false;
frame.len = 8;
// Populate the payload bytes with accelerator pedal 0x3F92
frame.data[0] = 0xCE; //length = 5
frame.data[1] = 0x50; //CEM module
frame.data[2] = 0xE6; //reply to A6
frame.data[3] = 0x3F; //accel pedal
frame.data[4] = 0x92; //16bit value
frame.data[5] = 0x24; //value
frame.data[6] = 0x01; //number of messages
frame.data[7] = 0x00;
CAN::transmit(frame);
