Good!
this is the second developer that I've made to program the 16F628, but also serves the 16F84.
The original I got it from this web . It is in English, but I think that is a big problem if you know a bit components. I the only one I have modified to have a more led that indicates when programming. You can download the schedule here .
This would be the modified circuit: and this is the list of components I used:
- R1 10k R2 15k
-
- 3k3 R3 10k R4
-
- 5.1v Zener Z1 Q1
- 547 BC
- C1 100 uF 16v
- red LED D1
- green LED D2
- J1 9F DB
- J2 DIL Socket 18
And this is what I have come to me:
This is the top view. This is the part of the tracks.
In the latter you can see how small it is.
I hope you like this practical. I've done for the laptop , the other I have is quite large and to use had to be wired, this program is more practical and more comfortable use.
NOTE: the pictures may not fence components in the same position, check the datasheet first.
NOTE 2: This link you have the settings I use for the programmer. By
