前面板测试工具

半年前，公司需要我设计一些工具软件来对部分硬件模块做测试

对DVB33110D-PS1前面板的测试流程如下：

1. 开机后, 自动点亮Standby LED.共阴二极管初始化显示----
2. 按下 Power, 共阴二极管显示8888, 放掉 SW1, 共阴二极管显示清空.
3. 按下Menu, 共阴二极管显示11:11, 放掉 SW2, 共阴二极管显示1111.
4. 按下CH-, 共阴二极管显示22:22., 放掉 SW5, 共阴二极管显示2222.
5. 按下CH+, 共阴二极管显示33:33, 放掉 SW6, 共阴二极管显示3333.
6. 按下OK, 共阴二极管显示44:44, 放掉 SW4, 共阴二极管显示4444.
7. 按下VOL+, 共阴二极管显示55:55, 放掉 SW7, 共阴二极管显示5555.
8. 按下VOL_, 共阴二极管显示66:66., 放掉 SW3, 共阴二极管显示6666.
9. 按下遥控器[OK]键, 点亮Lock LED, 熄灭Standby LED,共阴二极管显示清空.

10. 按下遥控器[MENU]，自动点亮Standby LED.共阴二极管初始化显示----.

测试完成.
