There are many methods to achieve frequency modulation, which can be roughly divided into two categories, one is direct frequency modulation and the other is indirect frequency modulation. Direct freq...
Friends of EEWORLD, when you get the LM4F232 evaluation board, you can take a look at my README FIRST summary first, I hope it will be helpful. I. Introduction to the development board1. The main reso...
I recently encountered a problem: The environment is as follows: The serial port under wince sends 15K data per second, my serial port read and write buffer is set to 4K, and the global data is set to...
This may still be an idiotic question. Can experts please tell me what types of storage devices are used in embedded development? What is the maximum hard disk capacity supported by WinCE? What is the...
My program is defined as follows: unsigned char *Camera_Menu_Chi[]= { AddressSet_Chi, IF_Clear_Chi, }; unsigned char *Camera_Menu_En[]= { AddressSet_En, IF_Clear_En, }; unsigned char *Camera_Menu[2][]...
