GE Ya, GU Jin-liang, XIA Yan, et al. Design of 2D PSD signal acquisition device based on DSP[J]. 2017, 36(7): 86-88+92. DOI: 10.13873/j.1000-9787(2017)07-0086-03.
a signal acquisition system is designed which implement PSD signal processing. Choose TMS320F2812( hereinafter referred to as F2812) as the main processor
which use F2812 internal ADC conversion module
complete target signal acquisition. Through digital signal processing
convert digital signals to position coordinates signals. Asynchronous serial port communication( SCI) is used to transmit to a PC. Through experiment
it is proved that this device has high reliability
and has function of high speed data acquisition and processing.
