RT I am a newbie, please give me some advice from the experts~~ In Win ce5.0, I currently need to abandon the input method and only use the mobile phone keyboard. I can use a switch key, such as #, to...
[color=#000][font=微软雅黑,]I wrote the data at address 20h-22h in C using assembly mixed programming, and then I want to read the data in C. Please tell me how to do it. Thank you. [/font][/color]...
There are three .C files in the library function file. What are the differences between these three files: DSP_mul32.c, DSP_mul32_cn.c, and DSP_mul32_d.c? If I want to call the DSP_mul32 function, whi...
Although it is small, it has all the necessary functions, such as AD, PWM, serial port, etc. It just lacks IO ports, which makes it suitable for small products. The description of each register and pe...
Recently, Japan's Toshiba Corporation has manufactured a 128MB output capacitor-free DRAM chip on an SOI (epitaxial silicon on insulator) wafer and is testing the chip. Toshiba reported the design an...
