I want to make a USB disk filter driver. First, I read the device descriptor of the USB disk, and then disable the USB disk according to a certain item in the device descriptor. Thanks to everyone's h...
The project at hand requires writing a software to monitor an RS485 networked device. The device is connected to the computer via 485 to 232. When the device is powered off or reports an error, the so...
I just started to use DSP, 2812, and learned to use three counter interrupts. The use of timer1 and timer2 are very normal, but the clock of timer0 cannot work properly. The function to be realized is...
Recently, I used a pulse transmission circuit designed by myself to excite the ultrasonic transducer, but no matter how I adjusted the oscilloscope, I could not observe an effective echo. The followin...
[align=left][color=#000]I encountered a problem when I was just starting to learn M4. I added the use of the ADC module to the TI official routine timers, and used a display screen driven by a common ...
I have been waiting for launchpad for half a month. Is it given out only after meeting the conditions? Or are there some conditions that are not met? Can you tell me what conditions are not met? Or ha...
