[avr-gcc-list] Passing a string variable to lcd_puts

[David VanHorn]

 

I was originally declaring my variable passed to lcd_puts as

 

signed char LCD_String[LCD_Line_Len + 1]

 

This, after discovering to my surprise that lcd_puts wants signed chars.

 

Recently, I've converted to the portable typedefs as

 

unit8_t and int8_t

 

Now, whichever of those I use, I get a warning:

 warning: pointer targets in passing argument 1 of 'lcd_puts' differ in signedness

According to stdint.h, int8_t is supposed to be signed, which I understand to be the same as char.

 

So what am I missing?

 

And as a secondary question, why does lcd_puts want signed data?  Seems nonsensical to me..
