就像在嵌入系统中使用C语言替代汇编一样,在嵌入系统中使用RTOS是大势所趋。原因主要是现在在大多数情况下编程效率比执行效率重要（单片机便宜嘛）。但纵观51的RTOS，keil c51 所带的RTX Full 太大（6k多），且需要外部ram，又无源代码，很多时候不实用。RTX Tiny虽然小（900多字节），但是任务没有优先级和中断管理，也无源代码，也不太实用。而ucosII虽有源代码，但是它太大，又需要外部ram，所有函数又必须是重入函数，用在51这类小片内RAM的单片机上有点勉强。于是，我借鉴ucosII和RTX Tiny编写了Small RTOS 51,虽然它为51系列编写，但是它还是比较容易移植到其它CPU上。

The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slewrate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.
