I've found an interesting circuit on techlib.com last day. It's a talking voltmeter (**broken link removed**). It uses PIC16F876-04/SP. I want to build it. But, in my locality that PIC is not available. So, can you suggest any alternative. Can I use PIC16F876A-I/SP? Please suggest me what to do. I've selected this one as a college project for my brother and need to complete it as soon as possible as we are running out of time.
Instead of grabbing a project off the net and trying to pass it off as original do a real project.
This would be a good starting point. Use a dsPIC with an ADC of 14 bits and enough memory to hold decent sound. Use Microchips sound libs. That sort of thing.
A science fair kind of thing is being conducted in his college next week. My bro is interested in electronics. He asked for my help to select any model. There is no compulsion that the project should be our own idea as he is informed by his teacher. He's just an intermediate first year (Grade 11) student.
I've checked the datasheets, pinout is same for both the micros, memory is same. I feel that i can go with 16F876A. What do you guys say, shall I proceed?
Strictly, they are not the same. The above migration document outlines the differences. For the purpose of the above project, I don't think the changes will cause an issue however.
Thanks a lot dougy83.
Migration guide really helps me. I'll buy 16F876A today and start building it. If I face any problem, I'll come back again.
Thanks guys!!
Bro....i doing tis talking voltmeter (Karen's Corner) alos for my project......now i have the PIC 16F876A..but i dono how to change the coding (can i have you coding pls)
