Library Example

This is a demonstration of the standard C library sprintf routine usage. Three different representations of the same 

floating poing number obtained by using the sprintf routine are sent via UART.

double ww = -1.2587538e+1;

char  buffer[15];

void main(){

  UART1_Init(4800);                         // Initialize UART module at 4800 bps

  Delay_ms(10);

  

  UART1_Write_Text(“Floating point number representation”); // Write message on UART

  sprintf(buffer, “%12e”, ww);             // Format ww and store it to buffer

  UART1_Write_Text(“rne format:”);         // Write message on UART

  UART1_Write_Text(buffer);                // Write buffer on UART

  sprintf(buffer, “%12f”, ww);             // Format ww and store it to buffer

  UART1_Write_Text(“rnf format:”);         // Write message on UART

  UART1_Write_Text(buffer);                // Write buffer on UART

  

  sprintf(buffer, “%12g”, ww);             // Format ww and store it to buffer

  UART1_Write_Text(“rng format:”);         // Write message on UART

  UART1_Write_Text(buffer);                // Write buffer on UART
