Description: 用PIC中档单片机集成的A/D模块，采集LM35输出的模拟温度值，采样速度为2Hz。然后将10位的A/D转换结果分为高低两个字节（高字节8位、低字节2位），通过USART模块的异步模式传到PC机上。通信方式设定为波特率9600、帧格式为8位数据位、无校验位、1位停止位。-Integrated with a mid-range PIC microcontroller A/D module, collecting the the LM35 output of analog temperature value, the sampling speed of 2Hz. Then the 10-bit A/D conversion results are divided into high and low two bytes (high byte 8, the low byte 2), spread to the PC via USART module asynchronous mode. Communication mode is set to the baud rate 9600 frame format to 8 data bits, no parity, 1 stop bit. Platform: |

Description: The present paper describes the design of a cost effective, better resolution data acquisition
system (DAS) which is compatible to most of the PC and laptops. A low cost DAS has been designed
using PIC12F675 having 4-channel analog input with 10-bit resolution for the monitoring of slowly
varying signals. The DAS so designed is interfaced to the serial port of the PC. Firmware is written in
Basic using Oshonsoft PIC IDE and burn to the microcontroller by using PICkit2 programmer. An
application program is also developed using Visual Basic 6 which allows to display the waveform of
the signal(s) and simultaneously the data also can be saved into the hard disk of the computer for
future use and analysis. Platform: |
