pic 16f72 project

[garg29]

could anyone please send me some examples based on PIC 16F72.or some projects related to this like a simple led glowing one will also do. so that i can practice it.

will be really thankfull .
eagerly waiting for your response

thanking you

It's just a 14 bit PIC, any 16F code will work with hardly any changes, and there's LOT's available on the net.

Check my tutorials.

thanks for your reply but i couldnot get any example specifically for pic 16f72.theres lots on 16f84.
please could you let me know on which site i can find the examples of 16f72.

As I mentioned above, they are all just 14 bit PIC's, they run the same code - with only very minor changes, due solely to their extra hardware.

It's highly unlikely you will find any 16F72 examples on the net, it's probably too new, but there's no need for it anyway.

Hello I'm Gayan From Electro Tech can I speak to devdev please........

Ahh devdev can you tell me do you need to turn off comparators in 16F72?Do you need STATUS reg for that?

PORTA is multiplexed with analog inputs so it needs to make digital inputs using ADCON1 isn't it?

PORTB is clear so it doesn't need to do anything.

As far as code is concerned, you can get by with modifying code for the '84 to the '72, but there is a big differnece in the chips themselves. The '72, for example, is a 28-pin device with completely different Vdd-Vss layout, for example.

If you want simple interchange between the '84 and another chip, take advantage of Microchip's very liberal sample program, and order out a 16F88, which is a lot newer chip, but basically the same as the '84 as to layout, etc.

hi devdev,

Did you read the date on that original post...
