1．EMIF 接口

TMS320F28335DSP 的扩展存储器接口(EMIF)用来与大多数外围设备进行连接，典型应用

如

连接片外扩展存储器等。这一接口提供地址连线、数据连线和一组控制线。ICETEK–F28335-A

将这些扩展线引到了板上的扩展插座上供扩展使用。

2．液晶显示模块的访问、控制是由28335ADSP 对扩展接口的操作完成。

控制口的寻址：命令控制接口的地址为 0x208001，数据控制接口的地址为0x208003 和

0x208004，辅助控制接口的地址为0x208002。

3．显示控制方法：

-液晶显示模块中有两片显示缓冲存储器，分别对应屏幕显示的象素，向其中写入数值将改

变显示，写入“1”则显示一点，写入“0”则不显示。-The 1.EMIF interface

Extended TMS320F28335DSP memory interface (EMIF) is used to connect with the most peripheral equipment, typical application

Such as

The connecting piece of extended memory. This interface provides the address lines, data lines and a set of control line. ICETEK- F28335-A

The extension line to the extension socket for plate on the expansion of the use of.

2 liquid crystal display module access, control by the 28335ADSP to the extended interface operation is complete.

Addressing control port: Command and control interface address 0x208001, the address data control interface for 0x208003 and

0x208004, auxiliary control interface address for 0x208002.

3 display control method:

- liquid crystal display module with two display buffer memory, respectively corresponding screen pixel, writing values will be changed to the

Change display, write "1" shows a little, write "0" are not displayed.
