I need to use HMC5883L to make an acceleration sensor to display the attitude angle and attitude coordinates on the LCD screen. I have never learned it before and don’t understand anything. I would li...
The software can display the network name, but it doesn't display after I set the shortcut key. According to Baidu's method, it still doesn't work after setting the user presence Diaplay-opengl. The r...
The selection of thermal relays is generally based on the rated current of the motor. For example, if the rated current of the motor is 3A, the thermal relay should be between 1.5 and 3.5. The setting...
Abstract This article introduces the CAN bus communication protocol and the module built into the new generation of Motorola embedded controller DSP56F805 for implementing CAN communication. It also e...
Can I debug a single project in PB5.0? I don't want to generate a new system image every time. Just like debugging in VS2005, I can modify the code and press F5 to start compiling, linking, deploying,...
