Can someone tell me why I am getting:
warning: passing arg 1 of `sendLCDcmd:'
discards qualifiers from pointer target type
mean? The warning occurs in:
//-------------------------------------------------------------------
// BackLightOn
//-------------------------------------------------------------------
- (void) BackLightOn:(int)minutes
{
char timout = minutes;
char * p = &timout;
[self sendLCDcmd:[[NSString
stringWithFormat:@"%1s%1s",BACKLIGHTON,p] cString]];
return;
}
//-------------------------------------------------------------------
sendLDCcmd is defined as:
- (void) sendLCDcmd:(char *)str;
The code runs fine, but warnings make me uncomfortable. -Chuck-
