Home Made Digital Tachometer for My Car with LED Bar Graph and Gear Shift Warning LED

Say, are you somehow related to the god, the master, the genius, the Ba'al, the wonder, the blessing from the heavens "eric malund"?
PS Erik - I have a lot of respect for you, you know that! Just joking again!
Michael,
OK, I am a twit. I never noticed no toolset was specified. I saw the reply from Mr Malund II and thought I could help as I did the same sort of thing myself for fun. I hoped the code I posted would help/encourage him to try and make his own.
Sanjeet,
I never made a PCB, it was just on a bit of stripboard. Apart from the micro there was an opto-coupler on the input and an LED 'bargraph' (and resistor network) on the output port. Oh and the usual crystal, caps and voltage regulator. The comments in the code aren't much use describing how it works, but if you are keen to learn then you should be able to figure it out.
The problem is it has nothing to do with keil tools, so we will get told off if the thread gets any longer. You are welcome to take the code and ask in a different general forum if you want help with it.
this is very bad,,,,,,,,,,
