Try to change the Xtall.

1v =1000 mv
2.5 v =2500 mv
2500 -1000=1500
1500 /100 =%1
i hope it will work :)

I am a beginner too but i can explain what # do
if u put a # infront of a value or a String the chip will send the characters in ASII format.See the ASII format table.

Thaks Bruce i looked to the web site that u post me but all of them for copper or other materials none of them can winding hot lead wire.Hot lead wire has a problem.If u wind the wire too fast it...

In the picture u can see bobbin cover with lead wire.I ask to the factory how do they do this they told me there is a machine controlled by microprocesor.After than i want the picture of the machine...

Ralph i learn electronic by my self.That means i really don't know what will i do when i have problem.I learn to read manuels and datasheet from this site.But some times i really can't find the...

test var byte
test2 var byte
value var byte
loop:
hserin [test,test2]
value=((test-48)*10)+(test2-48)
if value=15 then
goto ok
else
goto fail

yes now i do the same.But i don't understan 1 think.Now i can sent 1 digit numbers how can i sent 2 digit numbers?
for example when i sent 15 it comes to pic 49 53.i try to use this code

I really don't undestand in proteus simulation program it say's it is working i set up the circuit in the real world and it is not working :( i looked every connection and there is no mistake it must...

i change the commands like u re suggestion
like this
serout porte.0,5,[1,13]
serin porte.1,5,t1
but this time nothing works
:(

I did all of them but not working.
1. Make sure your Pins that you are using are I/O pins.
2. Make sure your chip is running (MCLR not on Reset)
3. Make sure there is no noise between the two...

I have the serial converter and a JDM programmer but converter's voltage is not enough.I lower the value of the resistance but this time i am having problem writing the pic.Now i want to ask...

Does anybody has parallel port multi pic programmer shema?Coz my laptop don't have a serial port.
