Hi
My current project involves using a JHD637 320x240 LCD .. i have searched everywhere and the attached file is the only information that i can find. Even i have send mails to the company asking them about the pin details and the timing diagram of the signals. But till now they have also not...
Hi Pranam77
The sound which jayananda mentioned is due to the improper timing of Triac/SCR which is a problem in the code and very minimum chance of a hardware fault.
I have done step mode charging for one of my client . If you can give me the pin details , i can try to build the code.
I hope...
if u can give the schematic i can build u code for it. atleast give the functions of the pins of PIC , like which pins are controlling the mosfets , is it active-high or actiive-low .. etc.

Dear venkey3777 & sahu
Sorry for the late reply . But i donot have the password...
Hi Pranam77
He had my schematic and pcb was also ready with him. Only thing he didn't have was the hex file. And after cracking the password to my zip file , he now has everthing including the asm code.
I cannot post the full project in the forum, if you want i can post the sinewave generation...
Don't depend on Mr.Shiddu's words. We had a deal that he will give me this design in exchange of the hexcode of the 16F72 based sinewave inverter. I sent him a demo version of the code for his testing. After testing he sent me password protected zipfile containing this design, he claims to have...
Hi
If you have a voltmeter , check the voltage at RA0 . If you are getting +5V at that pin , then you need to check the LED and the LED connection. There is no problem with the code. Can you post the hex code that has been generated by your compiler....
And connect a capacitor to the MCLR pin...
