摘    要:为了使现场智能设备能够更好地应用于运动控制等对实时性要求很高的控制领域,SHCAN2000现场总线控制系统在升级换代中使用了TI公司最新的32位处理器TMS320f2812。这套系统中的现场智能设备通过CAN总线互连来完成通信功能。由于C语言自身的优点对CAN控制器开发带来的诸多好处,介绍了用C语言对TMS320f2812芯片中的CAN控制器的开发,其开发与调试周期缩短,排除故障的能力就会大大增强,可更广泛地应用到运动控制领域中。

Abstract:For the sake of making smart device applied to control field which have higher demands of realtime property such as motion control,SHCAN2000 fieldbus control system selects the most resent TI chip of TMS320f2812 which has 32-bit data line during the process of the upgrade. Field Smart devices interlinkage with CANBus to accomplish communication function in the system. Because the virtue of C language itself takes many benefits to development of this CAN system, it is introduced how to use C to develop CAN controller in TMS320f2812 chip. The development and testing period is deduced,the ability of fault avoidence is increased. It can be widy used in motion control proplems.
Keywords:SHCAN2000  TMS320f2812  mailbox
