| Abstract: | The dual TMS328F28xx system is composed of two pieces of TMS320F28xx, one of the chips is used for digital filter, the other is used for control arithmetic. The communication was realized by inquiry and interruption through FIFO mode of SPI. In data acquisition, A/D conversion chip is used for each analog signal, chose the XZCS6AND7 to start up multiple A/D conversion at the same time through logic circuit, and read conversion data from every highway was latched. The data was processed by using filtering method of anti-pulse annoyance value (order cycle is 4) and median (order cycle is 5). |
