摘要
设计了以单片机ATmega 16为控制核心,以AD7705为前端采集芯片,以CPLD芯片EPM3064为逻辑开关阵列的32通道模拟量采集系统。给出了相应的硬件电路、驱动程序以及应用软件,指出了AD7705在实际应用中应当注意的一些问题。该采集系统结合测量仪器可以完成多点多参数的测量。
A 32-channel analog acquisition system,which has microcontroller ATmega 16 cored and the AD7705 been a front-end acquisition chip,and the CPLD EPM3064 been a logic switch array,was designed,including the presence of hardware circuit,the driver procedures and application software,and some problems the AD7705 encountered in practice.The testing results show that the system can complete multi-point and multi-parameter measurements after combining with other measuring devices.
