Abstract
SP180S nanoelectronic development and design by the Wei and the public all the information on a free hardware and software programmer, using the USB munication and power supply, pany currently supports Atmel MCU used AT89C and AT89S support the SST and some AVR MCU Series microcontroller, and supports AT24Cxx, AT93Cxx series Serial Eeprom's programming to meet the single chip microcontroller for beginners and enthusiasts to learn the requirements of 51. SP180S sophisticated hardware design, software functions, (a professional universal programmer all the functionality of the software), and have a special forum to provide technical support to ensure your DIY ess!
Printed circuit board technology is developing rapidly in all fields has been widely used. The design as a starting point, combined with the basic principles of microcontroller programmer to AT89C51 as the core, in Protel 99SE platform designed from the circuit, and in Protel 99 SE platform, the SP180S USB programmer a detailed schematic design and PCB design. The first circuit from the system under control, munications, DC / DC Conevert three modules of the circuit design, the final integration of all modules of PCB design, PCB design and introduced the parameter settings, routing rules. PROTEL circuit design using schematic design software, PCB layout, to consolidate the SCM applications, analog circuits, digital circuits PROTEL course and learn the u
