Hey Guys thanks for the replies
The microcontroller I am using is the MC68HC908JB8. it has
a a USB module which is designed to serve as a LS USB device. The MCU does not have a SCI (so I might have to implement a bit banging technique). If any one has any ideas as to where i can find some boot...
Hey everyone,
How is it going? Has anybody ever written a program to program a Microcontroller (that has a built in USB port) via its USB port.
If anyone has any ideas please let me know
Thanks a ton

Guys.. here is what i did and I think it fixed the problem.
I stuck with the zener and used a decoupling circuit to decouple my power supply into the MCU circuitry. I moved the relay away from the MCU circuit and that helped too.
When I get my new PCB i'll keep y'all informed. Thanks a bunch

I apprciate your help....
I think I have figured out the problem. Let me begin my explaing what i have... I have 3 circuits.... A charging circuit (charges the battery), and inverter circuit (in a black box.. I cannot redesign that) and a daughter board (this is where the microcontroller is...
I have the diode across the relay.
The load (a lamp load) is primary ont he normally-closed contacts (no load on the normally open)
When the relay switches from normally open to normally closed, it does not reset the micro but when it switches from normally closed back to normally open it...
Hey all,
I need some help in designing a MCU system. I have a set of 4 relays and one of them switches an inverter. I have a MCU monitoring the system and so everytime the relay switches the MCU resets itself (noise). I am working on different PCB layouts so as to keep the relay as far away...
