故障排除

使用任何新器件时都会碰到一些常见问题。通过检查本文档前半部分的操作说明，许多问题可以迎刃而解(如电路板连接和工程配置)。下面是另外一些常见问题和解决方法。

Problem	Possible Solution
When I compile my application, I get an "undeclared identifier" error each place I use a MAXQ2000 register.	Make sure you have the line #include <MAXQ2000.h> at the start of your application.
When I select Connect MAXQ Serial to JTAG, I get a "Device is not responding" error.	Make sure: that both boards are connected and powered up; that the JTAG cable connects with the red wire going to pin 1 on both sides; and that jumpers P2 (on the Serial-to-JTAG board) and JU11 (on the MAXQ2000 board) are both closed.
When I select Connect MAXQ Serial to JTAG, I get a "Cannot open serial link" error.	Make sure no other software is using the COM port you have selected. Often, PDA software will own the serial port from the time you boot your computer. You can either choose a different COM port, or turn off your PDA software.
The LCD segments are scrambled when I run the demo application.	Make sure that the LCD daughterboard is hanging off the top side of the MAXQ2000 Evaluation kit, not in the position where it hangs downward over the center of the board.

结论

MAXQ2000是功能强大的低成本、低功耗微控制器，具备支持多种应用系统的丰富外设。在Rowley Associates提供的MAXQ开发环境CrossWorks的支持下，可以用C语言编写复杂应用程序，并借助这个强大的工具进行调试。这样，可快速向市场推出高质量的产品。
