I would like to configure the can_onchip example for a CAN bitrate of 500kbps instead of the 125kbps default. Can this be accomplished simply by changing the values in the ClkInitTable?

// 500kbps
uint32_t ClkInitTable[2] = {
0x00000005UL, // CANCLKDIV 5
0x00002301UL // CAN_BTR 0x2301
};

//instead of 125kbps
uint32_t ClkInitTable[2] = {
0x00000000UL, // CANCLKDIV 5
0x00001C57UL // CAN_BTR 0x2301
};

Calculating the bit time quanta seems a little :(

Forgot to mention that I am using the LPC11C24 micro...

Didn't check your values, but changing this table (before it is loaded) is the right way :)

Edit: Checked your settings and yes, it's 500k :eek:
