Well ive been reading through the posts in this area and lots of people ask for a rev counter (Tachometer) but i cant seem to find any full examples, so i decided to go through all my zip files and shure enough. EPE did one a long time ago so long in fact that the back issue is no longer available. so firstly here is the code...
i know this if for a very old chip but that could be easily changed and below is the diagram, please be advised i have not tested this but as i said it is a nice place to start, and im sure if it has any mistakes the members will spot them, and make corrections as necessary.
Code:
DEVICE 16F84
DECLARE XTAL 4
DECLARE LCD_TYPE 0
DECLARE LCD_DTPIN PORTB.4
DECLARE LCD_ENPIN PORTB.3
DECLARE LCD_RSPIN PORTB.2
DECLARE LCD_INTERFACE 4
DECLARE LCD_LINES 1
PRINT $FE,128
W0 VAR WORD
START:
COUNT porta.0,1000,W0 ' COUNT FOR 1 SEC
W0=(W0*10)/2
CLS
PRINT DEC W0*6," RPM "
GOTO STARTi know this if for a very old chip but that could be easily changed and below is the diagram, please be advised i have not tested this but as i said it is a nice place to start, and im sure if it has any mistakes the members will spot them, and make corrections as necessary.
