This is more of a C problem than Arm problem, here too are some people who know their C.
I am reading the value of DWT_CYCCNT;
When print it via Uart, after a while it becomes negative. The most signicant bit becomes 1, but how to tell it to the compiler that it is not a sign.
//the declaration
char
klaa[40];
//the code
while
(1)
{
kellopulshit = *DWT_CYCCNT;
sprintf
(klaa,
''Clock pulses %d \n''
, kellopulshit);
c=
strlen
(klaa);
HAL_UART_Transmit(&huart2,(uint8_t *) klaa,c,1000);
