項(xiàng)目管理知識(shí)體系（Project Management Body of Knowledge, PMBOK ® ）是美國(guó)項(xiàng)目管理協(xié)會(huì)（PMI）對(duì)項(xiàng)目管理所需的知識(shí)、技能和工具進(jìn)行的概括性描述，現(xiàn)已成為國(guó)際社會(huì)普遍接受的項(xiàng)目管理知識(shí)體系標(biāo)準(zhǔn)。 《項(xiàng)目管理知識(shí)體系指南》（《PMBOK指南》）對(duì)項(xiàng)目管理知識(shí)體系的子集進(jìn)行了專(zhuān)業(yè)分類(lèi)和描述，定義了項(xiàng)目生命周期、5步流程和9大知識(shí)領(lǐng)域。
This example Project shows how to use the IAR Embedded Workbench for ARM
to develop code for the IAR-STM32-SK evaluation board. It shows
basic use of I/O, timer and the interrupt controllers.
Displays running lights on the board LED s.
This Project shows how to use the IOKit notification mechanism to register to be notified when devices come and go. It uses the Cypress/Anchor EZ-USB chip. (Look at the following example for another way to get notified when a device is unplugged).
