Has anybody successfully built this instrument? (Elektor 5/2004)
I tried but failed

-
The LCD display shows only "rubbish" and there is no indication of speed or direction on the PC screen.(I noticed the missing ground connection to the DB9 connector!)
I have pulses from the sensors! All components and connections are checked
I tried several different PIC:s - no improvement
I tried to re-compile the assembler code - lots of errors in MPLAB
Any ideas - anyone?
