mips development board

If you want to own a Development Board without spending any money, you can create a virtual development board by yourself. A Virtual Development Board is a board simulated by QEMU. It i

LinkIt 7697 is a versatile and affordable development Board that can be used to connect to your network or to your devices, while providing both Wi-Fi and Bluetooth online capabilities. The Development Board uses the MediaTek MT7697 chip, which is a little bit less than the ESP32 microcontroller used in other similar w

Well, we finally have to deal with data storage, please forgive me to skip a lot of basic knowledge, is really a practical practice to wait ~ ~ Haha! Simple message board, relying on TXT to store data, just an exercise. Next, let's start with the database, this post is just a warm-up. Look at the effects and source code: The above is the Android programmer to learn PHP development (26)-Simple message

This time in the processing of the board problem has made several mistakes. 1, although VCC and GND are short, the first reaction is to recall what operation caused the accident, in order to determine where the problem. 2, although the problem is located in the chip by electrostatic breakdown, but the removable chip did not go to confirm the error, (which caused a series of subsequent problems) 3. After the change of the film, found VCC and GND or sho

We can find from the schematics diagram of the smdkc210 board that the gpio port corresponding to led4 is gpx1_4, for more information, see my o

PCB design PCB design is completed under alicloud designer winter 09.PCB Creation The PCB Board is made in the laboratory using the thermal transfer method. Use dual-sided copper clad plates to separate two sides for corrosion. The process is as follows: Welding Based on the PCB component distribution chart, the components are sequentially welded to the PCB by the function module. After a module is welded, a module is tested and adjusted until it

Developing small applications on Android can accumulate both knowledge and fun, unlike task-based development, so it's a good idea to implement a simple doodle board on an android practicing. code implementation of Graffiti Board application New Project Mywall, modify/res/layout/main.xml file, add a Surfaceview and two button inside, use relativelayout layout,

Tutorial: Compile u-boot1.1.4 and above to start the development board based on S3C2410 -- Linux general technology-Linux programming and kernel information, the following is the details to read. Someone has tried to compile U-BOOT 1.1.4 or above to start the S3C2410/SMDK2410 compatible development board? I recently tr

Recently debugged the serial port above the bottom of the s5pv210 you made. Because writing a program is cumbersome to test a serial port. So, a direct transplant of a minicom onto the development Board. This allows the serial port to send and receive directly. Especially when I need to test multiple serial ports at the same time, faster than writing programs. No more nonsense, look at the operation flow be
