Now I modified the delay routine So you changed this:
delay() //delay routine
{
unsigned char dly2;
dly2 = 0x100; //0x20
while(dly2 != 0x00)
--dly2;
}
To this:
delay() //delay routine
{
for( dly2 = 0; dly2 < 12; dly2++ );
}
Did you actually read my post? I said:
How have you proved that this produces - and will always continue to produce - the correct delay in accordance with your device's timing requirements?
http://www.8052.com/forumchat/read/183229 The same question applies to your modified routine! Did you follow the links that I gave? Here they are again: http://www.8052.com/forum/read/182476 http://www.8052.com/forum/read/162556 Do you understand the intrinsic flaw with writing delays in a HLL? Now can any tell me the mistake in this code. What debugging and testing have you done yourself? Have you run it in Simulation - either "manually" (using pencil & paper), or in a simulator application? See: http://www.8052.com/forum/read/169932 And: http://www.8052.com/forum/read/169325 And: http://www.8052.com/forum/read/169331 Here are some more debugging tips & techniques: http://www.8052.com/faqs/120313 http://www.techonlineindia.com/article/0...anner.aspx |
