Zeroplus Technology issues two Protocol Analyzers presently, namely, DM114/DM115 dedicated to LED Display and DS1302 with the Timing function. Because of the feature, Energy Saving and Emission Reduction, the Photoelectric Industry becomes much hotter and the sales of photoelectric products become much higher. The Protocol Analyzer DM114/DM115, which is developed by Zeroplus Technology according to the DM114/DM115 protocol issued by Silicon Touch Technology, is the constant current driver specifically designed for the applications of LED Display. Specifically, it belongs to a kind of 8-Bit Shift Register. its maximum Clock Frequency is 25MHz and the range of its input voltage is between 3.3V and 5V; it mainly has four signal channels, namely, CLOCK, LATCH, SERIAL IN and ENABLE. ZEROPLUS Protocol Analyzer DM114/DM115 can be used to analyze the packet, DATA, in the DM114/DM115 signal; and it also can be used to set the Signal Pins, which will be connected with the CLOCK, LATCH, SERIAL IN and the ENABLE. At the same time, it is convenient to use the Protocol Analyzer DM114/DM115. So with the help of the Protocol Analyzer, it can improve the working efficiency. ZEROPLUS Protocol Analyzer DS1302 can be used for the Timing Control. The DS1302 protocol, launched by DALLAS, is the Trickle-charge Timekeeping Chip. It contains a Real-time Clock/Calendar and 31 bytes Static RAM and communicates with a Host via a simple Serial Interface. Specifically, the Real-time Clock/Calendar provides seconds, minutes, hours, day, month, week, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. And the Clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. The DS1302 mainly has three signal channels, namely, SCLK, RST and I/O. And its frequency is 2MHz. Specifically, the DS1302 utilizes three channels to transmit the corresponding signal, which is similar to that of the SPI. The Protocol Analyzer DS1302 can be used to analyze the packets (Read, Write, Address, Data) and other packets about time ( such as, Year, Month, Day and so on) in the DS1302 signal. Zeroplus Logic Analyzer can support more than seventy Protocol Analyzers at present, which are convenient for the developers in the relative industries to analyze and debug the corresponding signals. At the same time, with the help of the multiple functions which are provided by the Zeroplus Logic Analyzer, such as Data Contrast and Filter functions. The packet of the signal can be displayed with the graphical mode, and the check and the analysis to the signal will be much faster and much more convenient. About ZEROPLUS Zeroplus Technology Co., Ltd was established in 1997. It focuses on the design of the peripheral products of computer games. In 2004, the business scope was extended to the electronic measurement instruments. Applying the advanced MCU programming technology, the company successfully developed the latest patented measurement instrument, PC-Based Logic Analyzer. The unique and innovative technology was accredited by a number of patents granted, and the regions or countries where the company applied for patents have covered the whole world and the number of the patent and the country continues to grow. Since the release in 2005, the Logic Analyzer has been widely adopted by tens of dozens of public-listed technological manufacturers in the IC industry and the tertiary educational institutions. The excellent sale has made the Logic Analyzer the most popular in the market.
