Hello Forum
Someone can tell me if the PIC16F88, can be replaced by the PIC16F88 I / P?
Complete assembly of the VDI with PIC16F88 I / P, but the screen does not light.
thanks
Look at the contrast potentiometer (RT1-20K). To regulate it to the right or left.
Thank you and Eduardo Silverdog
It works!. The 20 K pot set at one end, to "0" volts.
Thank you very much to all who made this project possible
Regards, Jose
I made some testing and it was showing #45 on screen with Cu and Fe
Y was connected to TLC27M4 pin 14 near DISC-potentiometer
X was connected to TLC27M4 pin 1 near DISC-potentiometer
+ and gnd from MD 9V battery
Being a geezer doing surface mount electronics is not by capability. I tried it and I don't have the skill to solder such small areas. My old eyeballs don't see that good.Do you have a non-surface mount version of the circuit board ?

I had a bit of a look at those atmega32 chips, it seems the smd's have 4 extra pins that the dip's dont
so maybe we will have to borrow hugo's magnifier

You are not alone with the eye sight thing. Poor vision has taken a lot of the enjoyment out of electronics for me in recent years. I really have to be motivated to build something now.
I have used magnifying lenses of various type with some success but it is a hassle. I have a couple of very small closed circuit television cameras that I am going to try next. If I find a combination that works, I will post it.
