Low-frequency signals data collecting system designing based on SPI bus
Abstract:The paper mainly introduces the working principle of system, and gives the hardware circuit and software designing. In the data collecting system based on SPI bus, the low-frequency analogical signals are converted digital signals, then the results are stored, processed and displayed, the system has the features of flexible, real-time and low-costing, and shows good application prospecting in low-frequency area.
Keywords: data collecting, SPI bus, low-frequency and slow-changing signals
