select project -- Build options. Go to the compiler Selection: Select gun arm GCC complier, and add the-G parameter to the first one so that the compiled program can be debugged by arm GDB. OK. After the compiler is selected, set the compiler settings --- complier and debugger. Select the compiler to set. Here, the gun arm GCC complier selects the toolchain executables label. It should be noted that the following complier C ++ complier linker .... All are the cross-compilation tool chains of th

STM32F103XX CORTEX-M3 series of chips containing three-way SPI channel, Red Bull Development Board used two roads, SPI1 connection at45db161b model SPI flash,spi2 connection ADS7843 touch screen signal processing chip, SPI3 is best not to use, Because there is a conflict with the JTAG pin, there will be problems in debugging. The em-stm3210e Development

Tethering technology has been widely used on mobile platforms. It can use mobile devices as an access point, and other devices can use Wi-Fi, connect to the mobile device using USB or Bluetooth. Recently, network devices have been debugged on the TCC8900 Development Board of Telechips. You need to implement simple Tethering in Linux and share the network connection with other devices in Wi-Fi Ad-hoc mode. O

This program is used with minicom ..... Note that this method is successfully tested on the tq2440 Development Board. For other development boards, find the corresponding code on the King Road !!! After several twists and turns, I finally saw that the program was downloaded to the target board. The specific steps are a

We found on the internet that hackers have transplanted the Kinect to Android and used the beagleboard platform. The company wants to work hard on the Kinect, so it needs to implement the Kinect on the company's Android Development Board. Record for memo. 1. Follow the hacker's tutorial to transplant it to the beagleboard C4 platform. It went quite well. However, the deep image can only be maintained for s

The buzzer is a hardware device on the S3C6410 Development Board that can control the buzzer by writing a specific value to the register.In the previous chapters, two complete Linux drivers were written: Word_count Drive and LED driver, two have one thing in common is a source code file.Code reuse can be divided into two types: static and dynamic. An important code consumer is about to be compiled together,

configuration, select the last item--save an Alternate configuration File , and then select OK to save the configuration.5. Enter the command: make to compile it (Root permission). What cross-compilation path configuration and support platform configuration, people embedded in the source code inside the makefile file has already been configured for you, this need not worry. Wait for the compilation to finish, enter the kernel source folder under Vmlinux, cross-compile successfully! two. Port

ESP8266-01 is a powerful module that can meet the needs of any of our IoT projects. Since its release, it has formed a very powerful community and evolved into an easy-to-use, inexpensive and powerful Wi-Fi module. Another popular open source platform is the Arduino Development Board, which has built up a large number of projects around the platform. Combining these two platforms will open the door for many

device data input (2) Mosi-master device data input, output from device data (3) sck-clock signal generated by the master device (4) CS-enable signals from the master device Among them, CS is to control whether the chip is selected, that is, only when the chip selection signal is a pre-defined enable signal (high potential or low potential), this chip operation is effective. This allows connecting multiple SPI devices on the same bus. I have introduced so much about the SPI bus theory.

Recently in the Debug msm8996 board, because the motherboard and LCD sub-board has not come back, so the first back of the core board is a headless Android Device. The core board has independent power supply, in addition to USB type-c, FAN, HDMI, TF card and key hardware modules, are now tuned, the effect as shown.Duri

The buzzer is also called PWM pulse width modulation, the basic principle is to control the buzzer by the pulse to open and stop. A buzzer is a hardware device on a development Board that can control the sound emitted by a buzzer by writing a specific value to the register. This section describes the principle of buzzer implementation and implements a complete buzzer driver that can be turned on and off. PW

There is a problem with tftp:timeout when you want to TFTP files from the PC:: Tftp-gr Gprsapp 192.168.1.38Tftp:timeoutCheck the network, you can ping the PC. The TFTP server for the PC has also been opened, and it is also possible to test the TFTP data transfer from the Development Board to the PC: it is open when the TFTP server on the Development
