I have made a K149A programmer, it programmes the 16f84a very well but donot programme the 16f877a .I have checked the hardware many times through out but there remains some problem it donot even detect the 16f877a .
I have used a 16F628A instead of 16F628.
Can some body help me about this problem. Is there an thing missing in (...)

When I needed a 16f877a programmer , I searched the web..
Yes I found many , but most of them are complex ( or at least not simple )
But I have found this programmer from my friend , it's very simple

we're now using pic16f877a, do you know some assembly codes for accessing/controlling the sim900?...just for example in filtering the text message that is received by the GSM or replying using the pic to the text received by the GSM.....tnx

From where can i download a good free pic simulator ( 16f84a & 16f877a in particular) other simulator found in MPlab , maybe a simulator where i can add leds and push buttoms.

CCS is not free :-(
bctang Please don't start to cry.... :cry: :cry:
You can use HI-TECH LITE for free
It support 12F629, 12F675,16C84, 16F84, 16f84a, 16F627, 16F877, 16f877a
As you see it can program 12F629 and 12F675 and both of them 8 pins :-)

Do you use Hitech Lite version ?
This version is not suppot PIC16C73.
HI-TECH PICC Lite compiler supports
16F877, 16f877a, 12F675, 12F629, 16F627, 16F627A, 16F684, 16C84, 16F84 and 16f84a devices

First, maybe your programmer can program only 16F84 not 16f84a. For example, programming methods are diffrent between 16f877 and 16f877a.
Second, I used to use JDM programmer with ICProg. For ICProg, I had to run a reg file for winXP. If you are using WinXP or NT system, you should do that. You can find this reg file from ICProg web site.

can these 2 PIC communicate? if can, how is the pin should be connected because i didn't find any Rx or Tx pin on these two.
i'm going to tun a dc motor controlled by pic16f84a, and i found it does not have a built-in pwm function. can anybody help me with the source code to run this motor? the compiler that i use is picc. thank you

As of Multisim10 only 16F84 and 16f84a are supported.
Proteus do support 16f877a, although its not free!

For PIC, people usually start with 16f84a, which has only a TMR0 module and no ADC/Comparator/SPI/UART module, but is used only to start off with PICs. Then you can move to 16f877a or better yet, 18F series and then to PIC24F.
Just out of curiosity, why are you deciding to come to PIC from 8051. Atmel has ATmega series of microc

If you check the datasheet of 16f84a, you will see that there is NO ADC. bogusmeister is asking for interfacing the 16f84a with an external ADC, namely ADC0808.
I haven't used external ADCs, so don't know much about them, but this site should provide plenty of

i want to ask the reason for using pic16f84a form you and alertlinks.
My dad told me to use the 16f84a to start with, since it has very limited peripherals, so I can get a hold of the very basics first. Then, I moved to 16f877a to learn about the peripherals. And from there, migrating between PICs was simple

But there is one problem :
As long as I connect the programmer to my circuit and after write the program , the PIC micro-controller always stay on reset mode. So if I want to run the Program I have to unplug the programmer connecto
