I bought a new homework board with bs2 chip.· I ran the Hello! program and it worked great.· Then it lost communication while sitting there.· The supply voltage is 9+ volts, the chip voltage is 4.27V.· Is it a voltage or communication problem?

    The chip voltage should be closer to 5V. Your supply voltage is probably nowhere near 9V. Try a new battery.
