Jonathan, if you click on your link we only see the textversion of the program.
But he can find the program in this topic, download Samples.zip and search the file.

I think you made a mistake, the program works well, I have made it a dozen times.

Your schematics shows displays with Common Anode and the program is made for Common Cathode displays.
You must change the program.

I have some remarks on pin3 of the displays, they are connected on the 12V line, while the transistors are connected on the 5V line?

Sir,
I am using ULN-2003 inverter cum buffer its output is low when input is high (since using 25mm 7segment display), the display is working but the 7segment display is not clear , the adjacent or unwanted segments are also lit as bit, when both the digits are same display is fine, on differnt digits a shadow of unwanted segment is there.
I am using transistors at 5 v, the whole circuit is working on 5V dc. i am sorry for the error in the schematic
Thanks
Mukesh

I have changed Jonathan's version.
Now the reflections are gone.

Give me some feedback please

Enjoy!

thankful & grateful for your valuable guidance (by Mukesh Pandey)
Respected sir,
I am thankful & grateful for your valuable guidance. The circuit & microcontroller 16F886 is working with the changes suggested by you. I am getting the required brightness using the old 4 Mhz crystal, since I am using only two 7segment displays.
Once again I heartily thank you for giving me your precious time.
I will always remember that I had an excellent guide in the form of you.
Regards
Mukesh Pandey
