Hey,
I'm designing a parallel parking car using the HCS12DT256. Everything has been great until it started restarting right in the middle of parking. It might reset after a second, or after 10 seconds, rarely it never does it.
The thing is that it used to complete the parking without resetting, then it started doing that although all the things that I have changed (hardware and software wise), I have removed it again to determine the source of error.
I have checked for shorts.
My power supply is a +7 volts dc power supply. Also used 9 volts batteries, both gave the same result.
I know that it resets because the LEDs blink and the car stops and waits for my Start input. However the VDD led never blinks.
There is no error in the software, I am 100% sure.
I have put capacitors around the power supplies.
Any ideas? Any suggestions how to prevent it from resetting?
