	Hi All, I've tried to get something going for timers under icc12, but seem to only get nonsense times coming out. My main clock runs at 8MHz, and I'm using the...

	Hi Guys, I'm working with the Metrowerks CodeWarrior MOT V1.2 Compiler for the HCS12. I've noticed that working with integers, long or float values, when you...

	Christine, If you haven't found it yet, look at myPT6(). You are setting timer7Count instead of timer6Count. Therefore, timer6 would run really really fast. ...

	Hi, Thanks for you help. I think the problem may even be a faulty BDM Multilink. I have tried plugging it in directly to the parallel port on three different ...

	Hi, I believe the BDM Multilink will draw more power during Flash programming so if your power supply is close to the requirements of your target system and ...

798		Andrei Chichak acpmiedm@...	Sep 4, 2002 8:53 pm
	The interrupt routine should disable the interrupt when the buffer is empty. The main processor should enable the interrupt when the buffer is ready to go. ...
