How should DSP be connected to parallel DA to output the processed data? The DSP of 5509A uses 8-bit parallel AD at the input end (occupying CE0 space and D0-D7 of DSP data line). How should the data ...
1. Introduction
I had just received the board and set up the development environment, but was stuck at the step of downloading the program. I felt that there were some problems when installing the dev...
[U][ip]A transformer is a device that transforms AC voltage, current and impedance. When AC current flows through the primary coil, AC magnetic flux is generated in the iron core (or magnetic core), c...
I am a novice. When I use wince5.0 to compile a new PB, the following error is prompted: making: FATAL ERROR:Cannot open F:\创建文件夹\2222\Reldir\smdk2440a_ARMV4I_Relea\postproc\platform.bib making: FATAL...
