PIC单片机中C30编译器中函数中用数组调用常数字符串问题

关于PIC单片机不能用数组来调用字符串的问题：
函数原型
void Print_5X8(unsigned int y,unsigned int x, unsigned char ch[],unsigned int yn)
{
unsigned char wm ,ii = 0;
unsigned int adder;
while(ch[ii] != ' ')
{
adder = (ch[ii] - 0x20) * 5;
Set_Ram_Addr(y , x);
for(wm = 0;wm < 5;wm++)
{
if(yn == 0)
{
WriteData(~Asc5X8[adder]);
}
else
{
WriteData(Asc5X8[adder]);
}
adder += 1;
}
ii += 1;
x += 5;
}
}
调用形式:
Print_5X8(0,10,"FTTx",1);
编译错误；pointer targets in passing argument 3 of 'Print_5X8' differ in signedness
恳请各路大神求助啊，我在c8051f060、以及MSP5419单片机的开发环境中都可以这样调用，在C30编译器就不行~
