STM8: Problem displaying ADC value Hi Guys,Based on some tutorials, I am trying to execute ADC module of STM8S105 and display the ADC result in 16x2 LCD display. The problem is : thousandth digit place is showing alphabetic character right from "A" when I increase voltage on ADC channel from 0. Please see my code as well as adc.h file. I am eagerly awaiting someone to suggest where I have made the mistake. #define LCD_RS GPIOD, GPIO_PIN_2
#define LCD_EN GPIOD, GPIO_PIN_3
#define LCD_DB4 GPIOD, GPIO_PIN_4
#define LCD_DB5 GPIOD, GPIO_PIN_5
#define LCD_DB6 GPIOD, GPIO_PIN_6
#define LCD_DB7 GPIOD, GPIO_PIN_7
#include "STM8S.h"
#include "lcd.h"
#include "adc1.h"
main()
{
//Variable declarations
unsigned int test_var ;
char d4,d3,d2,d1;
gpio_adc_init();
adc_init();
Lcd_Begin();
Lcd_Clear();
Lcd_Set_Cursor(1,1);
Lcd_Print_String("STM8S103F3P3 LCD");
delay_ms(5000);
Lcd_Clear();
Lcd_Set_Cursor(1,1);
Lcd_Print_String("Circuit Digest");
Lcd_Set_Cursor(2,1);
Lcd_Print_String("Test: ");
while (1)
{
test_var
