Blackfin has been selected in 3G baseband processor. It has been used in WCDMA, TDSCDMA, and Wimax.

It is a new single core DSP+RISC processor, and has bundle of channel coding struction, low power consumption.

Blanfin一定会有进一步的飞跃,期待着

但是:

Currently, the Blackfin does not have a built-in touch screen controller. Analog Devices does make discrete touch screen controllers like hte AD7843 which connect very easily to the Blackfin SPI port.

由于没有自己的触摸屏,因此,我想借助于AD7843自己写触摸屏一个驱动,大体的思路如下:

1 include touchScreen驱动需要的库

2编写touchScreen的fops

3编写touchScreen的open函数

4编写touchScreen的read函数

5编写touchScreen的poll函数

6编写touchScreen的release函数

目前就想到这些,大家可以交流一下,为我们的blankfin做出更大的贡献!!!
