Abstract
The invention relates to the technical field of communication control, specifically disclosed is a data communication method of Arduino Due and an FPGA. The method comprises the steps of configuring the first level intensities of the communication signal pins of the Arduino Due and the FPGA respectively; when the clock signal pin is an input pin, configuring the level intensity of the chip selection signal pin as second level intensity, and starting to write data from Arduino Due to the FPGA or read data from the FPGA by Arduino Due; if it is detected that the input pin triggers an interrupt response, completing the data writing from the Arduino Due to the FPGA or data reading from the FPGA by the Arduino Due at a time; when the clock signal pin is an output pin, if it is detected that a chip selection signal of the chip selection signal pin drops, starting to write data from the FPGA to the Arduino Due or read data from the Arduino Due by the FPGA; and if the trigger response of the output pin is detected, completing one-time data writing from the FPGA to the Arduino Due or data reading from the Arduino Due by the FPGA. Through the method, the rapid data communication can be carried out between the Arduino Due and the FPGA.
Description
technical field [0001] The present application relates to the technical field of communication control, in particular to a data communication method and system between Arduino Due and FPGA. Background technique [0002] The development of electronic information application technology has driven the rapid development of integrated chips and software tools, making integrated chips based on C / C++, python, Java, verilog HDL and other languages widely used. Among them, C / C++-based ARM, DSP, verilog HDL-based FPGA and its integrated embedded system are widely used in actual signal processing, motion control and other fields. Since Massimo Banzi and others developed Arduino in 2005, there have been many Arduino models such as Arduino Uno, Nano, Mega2560, Due and many other extended hardware platforms such as Arduino GSM Shield, Wireless ProtoShield, WiFi Shield and Motor Shield. Among them, Arduino Due uses AtmelSAM3X8E CPU chip, which is the first Arduino model based on 32-bit ...
