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
What do you mean by, "there is no data" ?
Show a complete example of your usage.
Say what you expected to happen.
Say what actually happened.
Say what you have done to investigate the problem ...
