Tool/software: Code Composer Studio
I'm beginer in Code Composer and 5416. Now I try to write easy code but this code dosen't work correct.
I think it is problem this stack.
void SPI_Delay(const unsigned int Del)
{
volatile unsigned int i=0;
for(i=0;i<Del;i++)
{
asm(" nop");
asm(" nop");
asm(" nop");
asm(" nop");
}
}
void main()
{
SPI_Delay(10);
}
When I call this the Del is not eqvivalnt 10..
