I'm working on AtMega88PA with well-working LCD display.

I've got 2 working methods from the internet:

```
extern void lcd_putc(char c);          // send one 'char' to LCD display e.g. lcd_putc('A')
extern void lcd_puts(const char *s);   // send more chars e.g lcd_puts("something")

```

And those are working great. However if I want to send **uint8\_t** LCD is showing weird symbol - 4 horizontal lines.

I've tried to project this integer using:

```
lcd_putc((char) integer); 

```

Both outside and inside function, with same result.
I also tried to convert a number from BCD to Decimal and otherwise.
It's same for unsigned char - for some reason when I try to display unsigned char same character appears on LCD display.

How do I convert other data types into char in C?
