measuring knock sensor on an engine.
Size mainly because the unit needs to be mounted and look as "nice" as possible.
With that said one could conclude that cars and looking good are part of my religon
As far as pins go, the 8-pin micro only has 5 pins to play with and I need one for the sensor input and 1 for an LED warning light output (to draw attention to the displayed value) As this value if large enough can result in death of the engine, yet another part of my religon...
With what I have read about the PIC's is that you can use serout and i figured it could do the serout command and then hit the parallel converter for the LED, and such. I might be trying too hard though as well.
EDIT: So nevermind on the 8-pin pic, I will go with the PIC16F684 then run a black ribbon cable for the LED Display.
Another EDIT:
PIC16F684 Has 12 I/O PINS
01 - Input from Knock Sensor
02 - LED on knock count (KnCnt) > 4 = Turn that flippin' LED on!
03 - Segment A
04 - Segment B
05 - Segment C
06 - Segment D
07 - Segment E
08 - Segment F
09 - Segment G
10 - Segment H
11 - LED Display A
12 - LED Display B
Would like to use alpha numeric display, because if knock count does go over a predefined count then I want it to display EE
Thanks for all help
