Abstract: | Introduce the multi-channel temperature measurement system based on FPGA and DS18B20 digital temperature sensor,To FPGA platform for the development, use of single-bus digital temperature sensor measurements and temporary storage of all DS18B20 temperature value,and FPGA control collection of the multi-channel temperature and drive the LCD module that has a good user interface (LCM) real-time display of all measuring the temperature. The programme is to facilitate the realization of multi- temperature measurements, flexible software programming, hardware control circuit reconfigurable, high reliability, high temperature measurement accuracy, a wide range of applications, and other characteristics. Experimental results show that the system control superior performance and procedures short time, run faster. |
