hi there,

I am try to define the array for LCM display and want to write a function for it.

like this..

const Byte pic[ ] ={......................}

main(){

show_pic(pic);

..}

void show_pic(char *ptr){

......}

But while I am compiling,the compiler shows the message

If I denfine the array in the RAM,then the compiler could finish the compiling.

Byte pic[ ]={......}

thank you for your kindly help..

Hello

I assume you are using CodeWarrior for HC08 V5.x.

In fact the compiler notifies you that you have passed a constant pointer to character to a function expecting a pointer to character.

This message is a warning per default as required by ANSI C standard.

You can disable this warning activating the option -Ec.

I hope this helps.
