LTC1099基于PC的數(shù)據(jù)采集板實現(xiàn)

A complete design for a data acquisition card for the IBM PC is detailed in this application note. Additionally, C language code is provided to allow sampling of data at speed of more than 20kHz. The speed limitation is strictly based on the execution speed of the "C" data acquisition loop. A "Turbo" XT can acquire data at speeds greater than 20kHz. Machines with 80286 and 80386 processors can go faster than 20kHz. The computer that was used as a test bed in this application was an XT running at 4.77MHz and therefore all system timing and acquisition time measurements are based on a 4.77MHz clock speed.

MAXX9257 MAX9258芯片可編程SerDes持續(xù)時間計算

The MAX9257/MAX9258 programmable serializer/deserializer (SerDes) devices transfer both video data and control signals over the same twisted-pair cable. However, control data can only be transmitted during the vertical blank time, which is indicated by the control-channel-enabled output (CCEN) signal. The electronic control unit (ECU) firmware designer needs to know how quickly to respond to the CCEN signal before it times out and how to calculate this duration. This application note describes how to calculate the duration of the CCEN for the MAX9257/MAX9258 SerDes chipset. The calculation is based on STO timeout, clock frequency, and UART bit timing. The CCEN duration is programmable and can be closed if not in use.

基于ATmega8的雙軸太陽跟蹤器設(shè)計

為提高太陽能的利用率，以ATmega8單片機為控制核心，設(shè)計了一套光電跟蹤與視日運動軌跡跟蹤互補控制的雙軸太陽跟蹤器。該跟蹤器在晴天時，利用光敏電阻采集光強判斷太陽位置,控制步進電機實現(xiàn)光電跟蹤；在陰天時，采集時鐘器件PCF8583的時間信息,計算當前太陽位置來實現(xiàn)視日運動軌跡跟蹤。實驗表明：該太陽跟蹤器能在不同天氣狀況下對太陽進行較準確地跟蹤，能量接收效率提高了30%，達到充分利用太陽能的目的。 Abstract: To improve the utilization rate of solar energy，a kind of solar tracking controller which effectively combined the sun angle tracking and photo electric tracking based on ATmega8is designed.In the sunny days，the solar tracking con-troller determines the sun's position by using photosensitive resistances to collect light intensity and control stepper motors to achieve photo electric tracking，n cloudy days，it collects clock chip PCF8583time information to calculate the current position of the sun and achieve the sun angle tracking.Experimental results show the solar tracking controller accurately tracks the sun in different weather conditions，improves received energy efficiency by30%and reaches the purpose of full use of solar energy.
