LCD display techniques for floating point data with decimals-EEWORLD

Collect

Generally, when displaying real-time values, we often use the sprintf function to convert the numbers into characters and then call the character display function of the LCD. For example:

u16 adcx;

float temp;
char aa[10];

  adcx=Get_Adc_Average(ADC_Channel_0,10);
  temp=(float)adcx*(3.3/4096);
  sprintf(aa,"%5.2f",temp); //Convert floating point data to a string of the specified format
  LCD_ShowString(152,150,200,16,16,aa); //Directly send character display function

This is very convenient, saving the need to create a digit processing function.
Note: Calling header files in the compiler environment
