I am using DVRRDK_03.50.00.05. How do I compile cmem.ko in this version? I modified MVTOOL_PREFIX in cmem's Rules.make, and then made it in the same directory, but cmem.ko was not generated. How do I ...
[font=宋体][color=black]The original plan was to use R7F0C80212+wireless to make a wireless module, but because I was busy with other things later, I could only make a simple one for now, which happened...
I use the 4+3-bit DIP switch to let the user set two data at will, and the program reads the two data and then processes them accordingly. I group the 0~3 bits of the PC port and the 4~6 bits as a gro...
