Question: How do I convert a float value to ASCII and display it on an LCD or transmit over a UART TX?
Answer: A float value can be converted to ASCII string using the ftoa function and then displayed on LCD using the LCD_PrString function or transmitted through UART using UART_PutString or TX8_PutString functions.
Code Samples
Display float on LCD
#include “stdlib.h”
int Status;
float MyFloat = 3.414;
LCD_Position(0,0);
LCD_PrString(ftoa(MyFloat, &Status));
Note: Code assumes that an LCD user module named “LCD” has been placed in the project and the LCD has been initialized
Transmit a float value as ascii string over UART
#include “stdlib.h”
int Status;
float MyFloat = 3.414;
UART_PutString(ftoa(MyFloat, &Status));
Note: Code assumes that an UART user module has been placed, configured and initialized)
