| Abstract: | Aiming at the disadvantages of long training cycle,low forecasting speed in using CPU to control multi-channel serial A/D converter and digital filter.A new method for controlling SPI multi-channel A/D converter using VHDL finite state machine and realizing arithmetic mean filter utilizing pipelining design was proposed.A temperature measurement and control system was designed based on TLC2543.Experiment result shows that this method can implement multi-channel data acquisition and digital filtering quickly... |
