I wrote a driver for a custom USB device under Fedora8, and it has been verified to be fine. Now I am porting it to arm linux. After cross-compiling the driver, it can be successfully insmoded to the
This program uses ADC0809 to collect the voltage output from RW2 and displays it on a seven-segment display. Now I want to write the displayed data to SBUF and send it to a PC. I have tried many times
When an AC voltage is applied to a capacitor, the capacitor should have a charging and discharging process, and the voltage across the two ends should not change suddenly. This is also the principle o
