Hai, I have some problems in my adc.
my adc is not responding for the following problem, I don't understand where is thee problem. my code is here.

Hai
I am using PIC18F4550 with USB (20MHz xtal). When i try to send data through UART, my serial port does not get the actual data that I have send.
When I try to send data 00-FF, only some values are correct (7,8,9, j,k,l,m & n). I think the problem is in my baud rate. I have tried...
Hai,
I have a pair of zigbee (X bee), when I am interfacing I hve the followin g problem.
1.When tx is my pc and receiver is 89c51 the o/p is ok and reverse is also ok.
2.When both tx and rx are 89c51 o/p dosen't get.
I have no doubt on Xbee bcoz both (Tx & Rx) are working well.
Also 89c51...
Thanks for your replay..
The vendor says that it is better to use default config. settings in keil and I have followed it.
But the hex file that have developed by the vender having a size of 3K and my code is in 2K only(same program of the vendor but new project).
These are the projects. Both...

my current problem is that, my board only works when i am editing the source file given by Rhydolabz.
When I copy the same program for my new project, it will not work in the board and the same is work in proteus.
This is the source file

I have interfaced zigbee with 89s51. I send data to the pc by using a seperate 89s51(from 00-ff).
I can send data via x-bee on pc (using X-CTU software)
But the data can't receive back.
I think the problem is in the receiver program. plz check my program...

can anyone help me plz.........
Re: 89c51 interfacing to LCD
you check the connection on your 3 rd pin of lcd, use a 4k7 pot here.
you don't need to connect any pull up for this.
make r/w pin grounded if you don't need to read data from lcd.
