Hi to all

I am new in STM32 and keil (I used Atmel chips) and now I am getting familier with them.

I made a project and I can send data to serial port with the following function :

"HAL_UART_Transmit(&huart1,(uint8_t *) "Hello\n\r", 7, 10);"

but I do not know why there is no data when I use the following function based on sprintf:

"sprintf((char *) buffer,"23");"


The thing is that the code is well compiled and there is no error but the function does not work.

Do I need to add some more code for sprintf function ??!!!


Help please
