QL200 is an integrated demo system for study and development of PIC Microcontroller, which is provided with four functions of experimental instrument, programmer, simulation interface and ICSP download cable. Enclosed with control CPU and combined with programming software which has independent intellectual property rights, the system is able to support over 90 percent of the experiments and development practices of PIC Microcontroller.

To easily study and develop all series of PIC Microcontroller's, only a set of QL200 demo system and a computer are needed. Based on programming functions, abundant on-board hardware resources, flexible expansion, free resource distribution, and ICSP download function for customer target board, QL200 can not only satisfy the demands of a beginner in Microcontroller study, but also meet the requirements of engineers in development of Microcontroller. In addition to a study & experimental board, QL200 is also a demo board of Microcontroller integrated with multiple resources.

• In addition to above characteristics,many humanized functions are designed in the development of QL200,For examples:

Over-load protection function: When there is over load in the demo system, the protection system will automatically start to avoid any damage of elements. After fault is corrected, the board will recover to work.

Auto-load of changed file function:To achieve seamless integration with MPLAB IDE and other development software, the changed current target code is inspected automatically and then is transferred into the updated file automatically. This function offers great convenience for study and development, which avoids the trouble in repeating load of target code.

Function to identify the figuration bit and EEPROM in the file automatically: When we write the configuration bit information and EEPROM data in the program, otherwise setup is not needed for programming. This function saves much time for regular change in program debugging and avoids the setup requirement for each program change.

On-board CPU on-line upgrade function: It is available to download the updated programming software and run to upgrade hardware, which will upgrade on-board CPU to the updated version so that it can support more new devices.
