The Command readout is not working realibly. -A schematic will follow, until then: PD3 is onewire data. +Though the schematic suggests bus-powered operation, the AVR's power +consumption may be too high for this to work. If connecting the AVR causes the +bus voltage to drop below 3V, consider replacing the capacitors with a ~4.5V +battery. Do not use a mains power supply -- it may not have the same GND as +the 1-Wire bus. # Building |
