I want to ask what is the function of the files folder under BSP? ? Does it generate any files after compiling the kernel? Or does it not participate in the compilation at all? ? I see that my files f...
The internet was down for two days, and I started surfing today. The sensortile USB driver doesn't show up after I installed it, and I don't know why. At present, we can only debug the program. The fo...
I want to make an electronic dictionary, but I don't know what system to use? My teacher recommended me to buy a QT210 development board, but I'm just learning ARM9, and I'm afraid it's not easy to ge...
The device outputs a 0-2V DC, such as a 1.5V battery. How can I read it into the computer through the RS232 line? Then write a program in JAVA to display the voltage value on the screen? And can it be...
