How can I control my filter driver to load only as a filter driver for USB mass storage devices? I saw that bushound's filter driver is loaded as a USB class lower filter. Now I only want to filter su...
The input voltage of LM2576 is 12V. When the total power consumption of my LCD backlight reaches 800MA, the inductor makes a terrible buzzing sound. I have tried the inductor connected to LM2576 from ...
Why do you need points to download? I know that I will offend many people after posting this, but I still can't help it. Unless the document you download is your own work, why do you need points to do...
I have just learned ucos-ii recently and want to port ucos-ii to mpc8247. I wonder if anyone has done related experiments and can provide a rough step-by-step guide. Thank you!...
This is the result I got when I used Windows to query the modem. But I used many debugging tools, sending at+gmm, but didn't get any response. Serial port speed 230400 Data protocol standard ec compre...
I am using MSP430F1121. For example, how can I collect 10KHZ pulses through P2.5 port? If I use P port interrupt to wake up the main program, I don't understand the counting part. Who can give me a pr...
