hi all, i would like to ask about how i can reduce the voltage car battery to suitable with my micro controller pic 18f452. im read alot about voltage regulator lm 7805 wit using heatsink..
1 more question, i would like to know how the capture function can operate starting frequency 0hz and above. my osc frequency 20Mhz in im using 8 prescale on timer 1. base on my calculation, the slowest frequency i can use is 9.54Hz. im desing this for my digital speedometer with TTL output from sensor. so i just want calculate the TTL output by using Capture mood.
there is another option for it?
