就像在嵌入系統中使用C語言替代匯編一樣,在嵌入系統中使用RTOS是大勢所趨。原因主要是現在在大多數情況下編程效率比執行效率重要（單片機便宜嘛）。但縱觀51的RTOS，keil c51 所帶的RTX Full 太大（6k多），且需要外部ram，又無源代碼，很多時候不實用。RTX Tiny雖然小（900多字節），但是任務沒有優先級和中斷管理，也無源代碼，也不太實用。而ucosII雖有源代碼，但是它太大，又需要外部ram，所有函數又必須是重入函數，用在51這類小片內RAM的單片機上有點勉強。于是，我借鑒ucosII和RTX Tiny編寫了Small RTOS 51,雖然它為51系列編寫，但是它還是比較容易移植到其它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.
