Atmel’s AT91SAM7FP105 is a low pincount FingerCHip processor based on the 32-bit ARM RISC processor. It features a on-CHip biometric engine performing enrollment verification and identification, an internal record cache of up to 25 records and a secure command protocol over USB, SPI, UART. This protocol enables an external host system or processor to control the onCHip bioengine functions, manipulate the record cache, and securely export record cache records for external storage. Together with the FingerCHip sensor device AT77C104B, it forms an embedded, secured biometric turnkey solution.

ST7787 芯片的SPEC，比亞迪2.4inchLCM的SPEC。The ST7787 is a single-CHip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and 320 gate line driving circuits. This CHip is capable of connecting directly to an external microprocessor, and accepts Serial Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-CHip display data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.

當前LCM的主流接口有并口和串口。并口引腳多，產生串擾，串口則沒有諸如此類的缺點。SPI作為串口家族的一員，具有高速同步、芯片管腳少和信號穩(wěn)定不產生串擾等優(yōu)點，越來越受到開發(fā)人員的青睞。但是，具有SPI的LCM并不是毫無缺點的，市場上以COG(CHip on glass)方式封裝的LCM大都是基于單工方式傳輸的，這將給開發(fā)帶來了非常大的麻煩。本文主要論述基于單工SPI的GUI開發(fā)方案，詳細地分析了基于單工SPI的GUI的開發(fā)開臺，論述并分析在GUI開發(fā)過程中遇到的問題，最后提出增加虛擬LCD的方案解決這個問題。

是英文 “ Surface mount technology ”的縮寫。即表面安裝技術，這是一種較傳統的安裝方式。其優(yōu)點是可靠性高，缺點是體積大，成本高，限制 LCM 的小型化。 是英文 “ CHip On Board ”的縮寫。即芯片被邦定(Bonding)在PCB上，由于IC制造商在LCD控制及相關芯片的生產上正在減小QFP（ SMT 的一種）封裝的產量，因此，在今后的產品中傳統的 SMT 方式將被逐步取代。

This program would work fine only with a specific flash tool through PC printer port under EPP mode.Program is capable of identifying flash CHip manufacturer, device type, capacity,... It also allows user to dump flash data, edit/revise the content of flash CHip on the Screen, and re-write them back to the CHip.

The TMS320C54x, TMS320LC54x, and TMS320VC54x fixed-point, digital signal processor (DSP) families (hereafter referred to as the ’54x unless otherwise specified) are based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. These processors also provide an arithmetic logic unit (ALU) that has a high degree of parallelism, application-specific hardware logic, on-CHip memory, and additional on-CHip peripherals. These DSP families also provide a highly specialized instruction set, which is the basis of the operational flexibility and speed of these DSPs.
