Hi, Want to build a speedo for a model loco, fould Pic-Agoras, in Everyday Practical Etectronic April 1997, designed by John Becker
This looks just want I want, wityh a few mod's, as it can work with various wheel sizes, does speed in mph & kph, does distance.
I got the original articals from EPE, and the asm file.
The asm file, is writen in TASM, which I have been able to convert back to normal ASM, as I am using Microchips MPLAB v8.
It was using a 16C84, I want to use 16F628, I have converted it, I think.
"Bike440asm.txt", is the orginal file I downloaded
"Bike4_extra.asm", is what I have done so far, for a 16F628.
I have build the circuit on a breadboard, but can not get the LCD initisise, I have confirmed the circuit works with another fiel just to drive the LCD, I have tried to also run the origanal on a 16F84a, but still can not get it to work.
I am very much a novice on PIC's so, it could be something very simple.
I can not understand how this file does set up the LCD, as it is very different to the ones I have tried, ie, Nigel's tutorials on winpicprog.co.uk.
Hope someone can help
