hi. great work with the 'Data Acquisition & Logging System Using AT89c51' project. i am planning to build this project. i want to ask if i can replace the AT89c51 with any PIC microcontrollers. If can, which PIC model should i use? and what modification must be done to the program? can i still use the same C-code to program the PIC and the visual basic code for the GUI? i hope u can help me.
Thanx for the help.
Keep up the good work.

hi neo,
as far as the VB part is concerned, u can keep it the same as long as the data sent to the PC by ur PIC follows the same pattern/speed as the 8051 did. But u have to change the C code according to the PIC architecture as the port definitions/control registers/interrupt structures of both 8051 and PIC are completely different. First u have to completely understand the logic used by abbas bhai in the project and only then start converting it step by step tp the corresponding PIC code. We are always there to help u out if there are any doubts.
Good luck

Thanx for the information. I'll learn the architecture 1st. But i'm not sure which PIC model i should choose. Can i choose PIC16F877?

Or if i wan to use other microprocessor from Atmel, can i use AT89S52 with some modification to the C code? If not, what Atmel microprocessor should i choose?
I hope u can help me because i dont know how to choose microprocessors.
Im really grateful for your help.
Thank you very much.

take a look into different architecture choices you have.. read them, analyze them and see which one is simpler to you.

PIC is good with lot of features..
