The PCA9535 and PCA9535C are 24-pin CMOS devices that provide 16 bits of GeneralPurpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and wasdeveloped to enhance the NXP Semiconductors family of I2C-bus I/O expanders. Theimprovements include higher drive capability, 5 V I/O tolerance, lower supply current,individual I/O configuration, and smaller packaging. I/O expanders provide a simplesolution when additional I/O is needed for ACPI power switches, sensors, push buttons,LEDs, fans, etc.

GPRS(General Packet Radio Service)是通用分組無線業(yè)務(wù)的簡稱。GPRS是GSM Phase2.1規(guī)范實(shí)現(xiàn)的內(nèi)容之一,能提供比現(xiàn)有GSM網(wǎng)9.6kbit/s更高的數(shù)據(jù)率。GPRS采用與GSM 相同的頻段、頻帶寬度、突發(fā)結(jié)構(gòu)、無線調(diào)制標(biāo)準(zhǔn)、跳頻規(guī)則以及相同的TDMA幀結(jié)構(gòu)。因此,在GSM系統(tǒng)的基礎(chǔ)上構(gòu)建GPRS系統(tǒng)時(shí),GSM系統(tǒng)中的絕大部分部件都不需要作硬件改動(dòng),只需作軟件升級。

WHAT MIME64 IS: MIME64 is an encoding described in RFC1341 as MIME base64.Its purpose is to encode binary files into ASCII so that they may be passedthrough e-mail gates. In this regard, MIME64 is similar to UUENCODE.Although most binaries these days are transmitted using UUENCODE, Ihave seen a few using MIME64, and I have had requests from friends thatI decode MIME64 files that have fallen into their hands. As long assome MIME64 continues to exist, a package such as this one is usefulto have.
