ST7787 芯片的SPEC，比亚迪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.

版本更新了一下，到5.84了，需要用VS.net平台进行编译运行，介绍与原来的一样！ 磁盘文件的安全删除，我们通常所执行的删除操作并不是真正的删除只是清除了文件的fat表内容，文件数据还在磁盘上，可以恢复，所以不安全。-disk deletion of the security document, we usually enforced by the delete operation does not really delete the file will simply remove the fat table of contents, document data on the disk is, can be restored, therefore unsafe.

Flex chip implementation File: UP2FLEX JTAG jumper settings: down, down, up, up Input: Reset - FLEX_PB1 Input n - FLEX_SW switches 1 to 8 Output: Countdown - two 7-segment LEDs. Done light - decimal point on Digit1. Operation: Setup the binary input n number. Press the Reset switch. See the countdown from n down to 0 on the 7-segment LEDs. Done light lit when program terminates.

Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux Main Features: * Creates a virtual encrypted disk within a file and mounts it as a real disk. * Encrypts an entire partition or storage device such as USB flash drive or hard drive. * Encrypts a partition or drive where Windows is installed (pre-boot authentication). * Encryption is automatic, real-time (on-the-fly) and transparent. * Provides two levels of plausible deniability, in case an adversary forces you to reveal the password: 1) Hidden volume (steganography) and hidden operating system. 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data). * Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS. Further information regarding features of the software may be found in the:http://www.truecrypt.org/

This document describes how to switch to and program the unisersal serial bus (USB) analog phase-locked loop (APLL) on the C5506/C5507/C5509A devices. Example assembly programs for programming and switching to and from the APLL are also provided in the attached zip file. It is assumed that the reader is familiar with the use and operation of the C5506/C5507/C5509A USB digital phase-locked loop (DPLL) and C55x™ Digital Signal Processor (DSP) IDLE procedures.

These are P-Channel enhancement mode silicon gate power fi eld effect transistors. They are advanced power MOSFETs designed, tested, and guaranteed to withstand a specifi ed level of energy in the breakdown avalanche mode of operation. All of these power MOSFETs are designed for applications such as switching regulators, switching converters, motor drivers, relay drivers and drivers for other high-power switching devices. The high input impedance allows these types to be operated directly from integrated circuits.
