Universal Serial Bus (USB) is a communications architecture that gives a personal computer (PC) the ability to interconnect a variety of devices using a simple four- wire cable. The USB is actually a two-wire serial communication link that runs at either 1.5 or 12 megabits per second (mbs). USB protocols can configure devices at startup or when they are plugged in at run time. These devices are broken into various device classes. Each device class defines the common behavior and protocols for devices that serve similar functions. Some examples of USB device classes are shown in the following table

In a preemptive priority based RTOS, priority inversion problem is among the major sources of deadline violations. Priority inheritance protocol is one of the approaches to reduce priority inversion. Unfortunately, RTOS like uC/OS can’t support priority inheritance protocol since it does not allow kernel to have multiple tasks at the same priority. Although it has different ways to avoid priority inversion such as priority ceiling protocol, developers still have some difficulties in programming real time applications with it. In this paper, we redesign the uC/OS kernel to provide the ability to support round robin scheduling and implement priority inheritance semaphore on the modified kernel. As result, we port new kernel with priority inheritance semaphore to evaluation board, and evaluate the execution time of each of the kernel service as well as verify the operations of our implementation.

一般使用PC Based Controller 都是當(dāng)作現(xiàn)場(chǎng)設(shè)備的一種，也就是要接受 主系統(tǒng)的命令，做一些操作控制。以Modbus 來(lái)看屬于Slave 的角色，隨 時(shí)等待接收Modbus Master 的Query Message，然后依據(jù)內(nèi)容做控制，最后 將控制結(jié)果以Response Message 回傳。本章將以ICP 7524 及ICP 7188E5 等 兩種設(shè)備分別設(shè)計(jì)Modbus RTU、ASCII 及Modbus/TCP 的Slave 應(yīng)用程序， 讀者可以將此兩種程序的架構(gòu)再延伸設(shè)計(jì)至各種實(shí)際應(yīng)用程序。
