图上只有排线到DLPC2607的部分,DLPC2607到DMD的部分没画,而且连DMD具体是啥都没写。
排线上就只有DMD芯片和一个Flash芯片,Flash芯片里面保存了DPP2607的软件和固件,就是不知道能不能用,DMD的相关驱动应该都在这个Flash芯片里面。
DLP® Technology for Near Eye Display
TI的这个文件里面第13页提了这个0.24寸的DMD,但是没有具体型号。
在网上找到了IPD635这个板子的电路图,但是看描述好像这个电路图有点问题。但是可以作为参考,希望有大神可以点亮。

向大佬们求助,尝试在荔枝派zero上移植rtthread,rtt启动后外设中断会进入swi中断函数里面去。
