摘要
介绍了数字信号处理器TMS320F2812芯片内部闪存(FLASH)的两种技术:CCS插件烧写技术和F lash281x_API库烧写技术。提出了一种利用算法、摆脱JTAG口,使用RS422传输方式进行FLASH程序烧写的方法。由于RS422具有抑制共模干扰的能力,通讯距离往往能够达到几千米,所以这种方法非常适用于机载、弹载设备的外场加载和远程控制,具有较大的实用价值。
In this paper, two methods for programming TMS320F2812 on -chip FLASH, which are based on CCS Plug- in and F281x Flash API respectively, are discussed. And, a new programming method through RS422 interface insdead of JTAG is proposed. Because of the good performance of RS422 on constraining the common mode interference, long distance communication can be realized , even several kilometers far. So that this method is very suitable for the outfield load and remote control of on - board or on - missile devices, and has great value in practice.
