CCS/MSP430F5438A: Debugger doesn't run the function

Tool/software: Code Composer Studio

Hello,

I have an interesting problem. I wrote a function to send a char array via spi protocol. The function's elements are the char array and the lenght of that array. If the array has 12 element and if i choose 12 for the lenght of array, msp430 step over that function. If that array has 11 elements and if i choose 11 for lenght of array, msp430 execute that function. Msp430 also execute for 13. By the way the char array's size is 30. I cant figure out why it happens.

Best regards.

Hi!

Hard to imagine what's happening - could you share some code?

Hello,

I call the function as below;
spi_send_set1(status_packet, 12);

The function definition is;
void spi_send_set1(unsigned char data[], unsigned char spi_count) {
unsigned char i = 0 ;
for( i = 0; i <= spi_count; i++) {
while (!(UCTXIFG &UCB1IFG)) ;
__delay_cycles(1000);
UCB1TXBUF = data[i];
}
}

I watch the status_packet while debugging and it has 13 elements from 0 to 12.

Best Regards.
