 Hex to decimal to character string conversion Posted: Sat Nov 10, 2001 5:20 pm I need to convert a 32 bit hexidecimal integer to decimal, and then to a string of characters that represent the decimal conversion to output to the LCD routine lcd.c in the PICC examples. Anyone ever accomplish this? Any hints appreciated. Thanks, Pat O'Keefe ___________________________ This message was ported from CCS's old forum Original Post ID: 1048

 Re: Hex to decimal to character string conversion Posted: Sun Nov 11, 2001 9:40 am I assume that you are talking about a string contains hex data. In this case you can use a modified version of the gethex() function in "input.c": byte gethex1(char digit) { if(digit<='9') return(digit-'0'); else return((toupper(digit)-'A')+10); } int32 gethex(char *inputString) { int32 retval; #byte retvalL = retval #byte retvalH = retval+1 #byte retvalHL = retval+2 #byte retvalHH = retval+3 retvalHH = gethex1(inputString[0]); retvalHH <<=4; retvalHH += gethex1(inputString[1]); retvalHL = gethex1(inputString[2]); retvalHL <<=4; retvalHL += gethex1(inputString[3]); retvalH = gethex1(inputString[4]); retvalH <<=4; retvalH += gethex1(inputString[5]); retvalL = gethex1(inputString[6]); retvalL <<=4; retvalL += gethex1(inputString[7]); return(retval); } main() { int32 lResult; char toConvert[9]; strcpy(toConvert,"1234ABCD"); // fill out the sample string lResult = gethex(toConvert); // convert the string printf(LCD_PUTC,"\%lu",lResult); // write it as decimal } :=I need to convert a 32 bit hexidecimal integer to decimal, and then to a string of characters that represent the decimal conversion to output to the LCD routine lcd.c in the PICC examples.

Check the manual and the help. ___________________________ This message was ported from CCS's old forum Original Post ID: 1059
