Description: 射频卡读卡程序,射频IC卡识别技术，通常由载有密码的射频IC卡来代替传统的键盘密码。读卡模块读出密码后，即产生输出电信号，继而驱动执行机构动作，或将密码（如卡号）送给外围对接设备（如电脑或单片机等）。采用射频卡读卡模块及感应体构成的特定系统中，因射频卡内码信号唯一且不可复制，因此射频卡不仅杜绝了非法复制密码，还为各种控制采用信息化管理创造了条件。-RF card reader procedure, radio frequency identification technology IC cards, usually containing the password from the RF IC cards to replace the traditional keyboard password. Reader module read out a password, as a result, the output signal, and then drive the implementation agency action, or passwords (such as logging) gave the external docking equipment (such as computer or microcontroller, etc.). RF card reader module consisting of sensors and the specific system, RF signal code card but not the only copy, RF Card not only prevents illegal copying passwords, but also controls the use of information management to create the conditions.

Description: SG12232C graphic LCD液晶编程-This is an evaluation use of a small graphics LCD module. Last summer, SG12232C graphic LCD module has been sold sold for 1500 Yens from Akizuki Denshi and I bought it. However I could not find good application for the LCD module and it was going to go to junk box :-) so that I tried to use the LCD module temporary.
Only displaying any still image is not cool, first I tried to display an audio wave form in real-time like a digital oscilloscope, and then an FFT spectrum analysis too. The spectrum monitor seems to achived nice performance, in view of it is realized with a cheap microcontroller.
This can also be applied to radio frequency band.
