Hello Everyone;
To send ASCII characters via USART I normally use Hal libraries and the function below;
HAL_UART_Transmit(&huart2, (uint_t*)"Hello", 6,10);
But, that one is for characters only. How can I send the value of an integer over USART as its ASCII characters ? Which functions and libraries should I use ? . . . For example (dummy program just to show my purpose):
int i = ADC read value; //Lets say i=15
printf(i); //value should be sent in ASCII characters, so 1 and then 5 should be sent in ASCII. . . .
Thanks for your help, Kind regards
Salih
hello mr pier , thanks for sharing the code
i have already tried your code by using sprintf() and itoa() and the result is same.let me explain it, the number will split into buffer one by one.
num = 49 // sprinf() or itoa() method buffer [0] = 4 buffer [1] = 9
maybe what he meant was to send a buffer with one variable
buffer [0] = 49
Why are you waking-up a thread that has been dead for over 2 years?
You seem to be confusing the numerical values with ASCII character codes.
If you want to send the value 49 (ie, 0x31) as ASCII coded, human-readable text, then you need to send the character '4' followed by the character '9'
ie, in your example:
buffer [0] = '4'; buffer [1] = '9';
That's not what the question asks, reread it
