The book says: Use the following command to compile vfifo.c: #gcc -c vfifo.c -D_KERNEL__ -DMODULE -O2 -g -Wall If there is no error, a vfifo.o file will be generated in this directory. But I got an er...
I am exploring wireless modules and fingerprint modules. I want to know what is the difference between the 3.3V after voltage reduction and the 3.3V on the transistor?Where does vi refer to 3.3V or th...
RT, I am working on the driver of DM9000. DM9000 has two physical addresses, one for writing I/O register instructions and the other for writing DATA. In the process of allocating virtual memory under...
