Hi All,
I think this is a sample question.
I am using 'fs_etpu_uart_read_receive_data' eTPU function to receive data.
Here is the code:
uint32 data = 0;
uint8_t errCode = 1;
while(1)
{
data = fs_etpu_uart_read_receive_data(11, &errCode);
if (errCode == 0)
{
//Postion 1
.........
.........
return 1;
}
If I sent just one byte from other side, my code will always reach 'Postion 1' and return the same data value.
It seems that I missed to clear a flag after I receive each byte.
Could anyone point out what is wrong in my code?
Thanks,
Ben
