| Code: | {
int8 j;
int8 i=0;

output_b(ax[i%4]);
for (j=55;j>90;j--){
delay_ms(j);
}

still problem ? |

Run your code in MPLABSIM.
Examine the values for i, j and portB.
Are they what you expect them to be?
The penny may drop, you SHOULD then understand what Ttelmah is saying.

Just another suggestion: To improve readability don't quote each and every message.
What you are doing is good usage in mailing lists but here you are on a forum website where everybody clearly sees all previous messages. Quote nothing if you are responding to the full last message. Quote a message part when you are responding to an older message.
For example, in your last post there is a full page of text on my screen with only two new words of you: 'thank you'. |
