i need help with this code for school im stuck on this part and i tried many different thing to do but i cant figure it out. its the same code that keeps coming iup error: stray '\' in program In function 'void loop()':
 In function 'void shiftOut(int, int, byte)':

heres the code i need to debug

try it and see what you get cause i have no idea what to change

Code:

rm0 = rowM & 0×01;
rm1 = (rowM>>1) & 0×01;
rm2 = (rowM>>2) & 0×01;

Notice the '×' in 'rm0 = rowM & 0×01;' ?  It is not an 'x'.  It is a smaller x, which is an invalid character in Arduino language (and C).

Replace all 0×01 by 0x01

It is a very subtle difference, if you cannot see it, just delete the existing × and write an x.

thanks that worked perfect i cant belive i missed that thanks......... i got another problem after fixing those X's



In function 'void shiftOut(int, int, byte)':
error: expected primary-expression before ')' token

in this part of the program

for (i=7; i>=0; i-) {

You need a double '-':

Code:

for (i=7; i >= 0; i--) {

Yes, the code needs a lot of "cleansing"... like correct datatypes, etc... there are a lot of datatype mixing operations that can make the code compile, but it will be difficult to debug during runtime.  remember that C "promotes" lower datatypes to higher onces during operations, but you need to know exactly what you are doing to get the desired results.

thanks everyone for the help the circuit should work now thanks............
