摘要
设计了以芯片HS-3282为核心的DSP与ARINC429总线通信模块。该模块可实现DSP与ARINC429总线之间数据的高速、可靠的传输。模块主要由数据收发电路和逻辑控制电路组成。数据收发电路主要采用HS-3282完成数据的格式转换。逻辑控制电路由DSP和逻辑门电路组成,DSP发出的控制指令经地址译码后直接控制HS3282芯片,使芯片严格按照数据接收和发送的时序工作。测试表明,模块可实现DSP与429总线之间的数据通讯。
The paper designed a kind of communication module using the chip HS-3282 as the core of the module. It transformed the data between DSP and ARINC429 fast and reliable. The module consisted of transceiver circuit and logic control circuit. Transceiver circuit mainly used HS-3282 to complete the data conversion. Logic control circuit consisted of DSP and logic gate. After the address decoding, control signals from DSP controlled HS-3282 directly for making the chip received and sent data strictly according to the timing of work. The result of test showed the module could achieve the data transmission fast and reliable.
