| Abstract: | In order to realize embedded temperature measurement system,an embedded resolution based on thermistor and TMS320F2812DSP is proposed.The hardware design project and software realization method are presented.The temperature measurement system is composed of DSP chip,FPGA controller,ADC converter etc.The TMS320F2812DSP controls the ADC converter by ADC controller which is on the DSP chip,collects the value of resistance,computes the temperature,and sends the results to communication system.Experiments results show that the temperature accuracy meets the design; the stable correct results make this method very ascendant in practical application. |
