I am trying to transmit around 10 CAN messages at a single instance. here is the logic iam using for S12x micro
#define NO_OF_TX_MESSAGES 10
for(index = 0; index < NO_OF_TX_MESSAGES; index++)
//copy all databytes from application buffer
buf_sel = TFLG;
TBSEL = buf_sel;
// form the correct idrs
// fill the data into data segment registers
buf_sel = TBSEL;
TIER |= 0x07; // enable interrupts
TFLG = buf_sel; // transmit the frame
TIER = 0x00;
1. Could somebody tell me if the logic is correct or can i make any improvements?
2. I always find not more than 3 messages being transmitted at a time
ex: i want to transmit 0x400, 0x401, 0x402, 0x403 ... 0x409 messages i find only 0x400, 0x401, 0x402 messages are only being transmitted. when i go through the data sheet it says 3 transmit buffers is this issue related to this.
could somebody help me on this? i am unable to proceed further without resolving this issue.
Please let me know if u did not understand or i missed something.
thanks in advance,
