do you mean digital radio scale? if so, see for LCD frequency counter design at **broken link removed** and for PIC16F628 associated software instead of 16F84 for the above hardware, at
**broken link removed** there is a reply by Vu2chs and the hex file is a t my program
I have made this and works well.
In the schematic above there is a small mistake that resistors R8 to R11 are shown pulled down. they should be pulled up. however the PCB is designed correctly. I have another layout made for this and if you wantto make, i could pass on the Layout to you.
