Communication between industrial computer and micro-energy pulse power supply with nanosecond pulse width

In the paper, a communication circuitry is constructed between industry personal computer and micro-energy pulse power supply with nanosecond pulse width. A single chip microcomputer belonging to C8051F series which can deal with both analog signals and digital signals is adopted. The chip is of universal asynchronous receiver transmitter (UART) which is an enhanced serial port with frame error detection and address recognition hardware. The UART are assigned Port pins in a priority order by configuring the special crossbar. The serial bus is fully implemented in hardware and makes extensive use of the CIP-51's interrupts, thus requiring very little intervention by the CPU. The serial bus does not share resources such as timers, interrupts, or Port I/O. Then, the communication soft is developed based on silicon laboratories IDE and Microsoft Visual C++. The micro-energy pulse power supply may be controlled by industry personal computer.
