firmware program design mainly shows the step of development and flowchart with corresponding code segment 固件程序設計主要說明開發(fā)的步驟和流程圖,并輔以相應的代碼段。
then it describes usb driver and firmware programming . particular design is given by several specific program examples 通過分析具體的程序例子給出了詳細的程序設計思路和具體的程序流程圖。
after that, this paper depicts the software design for ccd camera system, including the usb device driver and firmware program 此外,對系統(tǒng)的軟件設計給予了詳細的說明,包括usb2.0接口的主機驅(qū)動程序、固件程序的開發(fā)。
in my practise stage, i design the usb transformation models with usb-rs232 module and usb-cf module, and finish the relevant circuit designs and firmware programming 在設計的實現(xiàn)階段,完成了相關的電路設計和固件編程,實現(xiàn)了具有usb_rs232、usb_cf轉(zhuǎn)換模塊的usb復合設備。
be superior to firmware program developed in assemble language traditionally, our program is completed by c language, which improves program's movable and legibility 與傳統(tǒng)的用匯編語言開發(fā)固件程序有所不同,我們所有代碼均以c語言完成,既提高了程序的可移植性又增強了程序的易讀性。
