SerReg is a small home controller intended to turn your personal computer ( PC ) into a process control / data collection system. With the appropriate sensors SerReg can monitor physical variables such as pressure, temperature, light intensity, weight, movement etc, process the information and then use the result to control up to three physical devices such as motors, heaters, sirens, lights or other appliances around the home, office, laboratory or factory . You can program your appliances to operate automatically in conjunction with your weekly and daily schedule, manualy turn them on/off from your PC or use SerReg as a process ON/OFF controller to regulate some kind of physical variable to the desired value.[more]
An iButtonTM is a chip housed in a stainless steel enclosure. The electrical interface is reduced to the absolute minimum, i.e., a single data line plus a ground reference. The energy needed for operation is โstolenโ from the data line (โparasitic powerโ). The logical function of the DS1990A is a simple serial number. This globally unique registration number is common to all iButtons. [more]
It includes RS232 send and get routines that let a PC communicate with the board. A few tests are built in - from a PC, you can send a character to the board to ask it to push a value to RAM, or send another character to pop from RAM and return the value to the PC. This way, you can push a few dozen characters, then pop them back to show the RAM is working. There also is RS232 code built in to run a Seetron LCD display. DRAM refresh is managed by the same ISR that runs the RS232 routines.
