In fact, this is a function pointer problem. The following is an example that has been called for your convenience. // For details, see C ++ premier 4. The 238 page is displayed. # Include Enum {abort = 0, fork }; Void showsignal (char sig){Printf (

In a twinkling of an eye, we have arrived at the last class-PWM-provided by the mini2440 manufacturer. The driver uses the timer 0 to generate the PWM pulse signal, and the gpb0 pin output is connected to the buzzer. The Code is as follows:   #

In the driver code, we often need to map the hardware address to the virtual memory, which is why we need to learn MMAP! The so-called cutting-edge without mistake, let's calm down and learn this very useful tool.   Prototype: void * MMAP (void *
