hardware and programming on it. For example, when you are writing a marquee program,
you can write P1 port or P2 port without any limitation on the hardware pre-connection.
You only need to change the connecting wires of the system. By this way, you are not
limited by the pre-connection among the hardware resources and have more intuitive
feeling about how the software is controlling the hardware deeply. Actually XL2000 is the
only development board which supports entirely open designing in the market.
2 high-quality technology:
This experimental box employs transparent Jacques power panels, with aluminum alloy
containers, made by machines with surface mount technology. The workmanship is
fabulous.
3. Super powerful hardware resources configuration:
It integrates almost all the possible functional module parts oriented to the real application
of this 8051 MCU. You do not need to find other components and it should be very helpful
for your development task.
4. Perfect sample programming examples:
With more than 10 years of 8051 developing and designing, we are offering programming
examples for each hardware module on the board. In addition to the sample code, we are
also providing step by step instructions, principle pictures and connecting method. We
hope our effort could speed your learning and developing embedded system.
5. USB communication connectors:
USB communication connectors could be used for ISP downloading and also power
supplying. It is not necessary to supply the board with an extra external power. It
facilitates the laptop users who have not LPT or COM port on his laptop. The single wire
connection makes it extremely simple and suit for debugging on the field.
6. anti-plug-protection:
All plugs are designed to prevent wrong plug-in. With connection pictures and clear
instructions, it is convenient for your learning even if you are a beginner.
7. More ISP downloading options:
You could choose either RS232 or USB for the communication between the development
board and the host PC. The communication is controlled by a separate 89C 2051 which
removes the impact on the host PC/OS and improves the stability. The communication
could be used as an independent ISP downloading interface for 51/AVR/PIC family ships.
Also, it could be used as an independent programming interface for 89S51/52 etc. chips.
8. Equipped with 40pin simulator head:
It could be used as an independent simulator for 51 MCU. With the help of KEIL software,
it supports on-line debugging like single step execution, break point and full run.
