Your write system call will be interrupted by the bus error signal SIGBUS, because you performed a bad memory access.
此时write系统调用会被进程接收到的SIGBUS信号中断,因为当前进程访问了非法内存地址。

The way how to read and write the large file of signal was also given, which will use only a litter memory.
同时,还给出了一个占用内存资源较少的大容量信号文件的读写方法。

The system select W78LE516 MCU and CPLD to construct the control circuit and use quickly read and write low power consumption, low-voltage external data memory CF card to save the signal.
