MCF5275的评估版原理图和PCB图嵌入式硬件设计资料(MCF5275 evaluation version of schematic and PCB design information embedded hardware chart)

LPC1766中的AD转换采用BURST模式，对8个通道进行电压采集，并将每个通道的数据进行均值滤波、数据转换，存入8个独立的数组中。(AD converter in LPC1766 BURST mode voltage collected eight channels, and each channel s data mean filtering, data conversion, stored in eight separate array. )

TM4C123单片机 SPWM模块使用，含主程序与库(TM4C123 SPWMmodule with main function)

读取DS18B20进行温度测量以后的结果并在1602液晶上显示。 基于DS18B20的温度控制器。温度控制范围在20~30℃，当温度大于30度时，停止加热，小风扇通电开始降温，绿灯亮。温度低于20度时，小风扇停止通电，开始加热。红灯亮。全过程有LCD数字温度显示。(Read DS18B20 temperature measurement after the results of the 1602 LCD display. Based on DS18B20 temperature controller. Temperature control range of 20 to 30 ℃, when the temperature is greater than 30 degrees, stop heating, small fan is energized to start cooling the green light. When the temperature is below 20 degrees, a small fan is stopped is energized, the heating is started. Red light. The whole process of LCD digital temperature display.)
