Embodiment Construction
[0024] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] The invention is a multi-interface protocol bidirectional conversion device, which uses FPGA as a control core unit to realize mutual conversion among four common interface protocols of RS232, RS485, SPI and IIC.
[0026] Step 1) Prepare to build the structure diagram of the multi-interface protocol conversion device
[0027] Such as figure 1 Shown: The multi-interface protocol conversion device includes: RS232, RS485, SPI and IIC external interfaces, FPGA control unit, protocol conversion parameter configuration module, TFT display module, power supply module and clock management module. First, set the protocol conversion parameters through the protocol conversion parameter configuration module, then collect the data into the FPGA through the interface, convert the external clock through the DCM clock management module to obtain th...
