There are two types of fixed-frequency PWM control: voltage mode and current mode.One of the main differences between voltage mode and current mode is the ramp input to the fixed frequency PWM compara...
The driver I made is named TMRMON. It compiles well, but when I run it on 2440, the following error occurs: TMRMON: DLL_PROCESS_ATTACH. Data Abort: Thread=83d71184 Proc=82026360 'device.exe' AKY=00000...
I have successfully transplanted the SD card driver in the S3C2410+linux2.6.13 environment. I can successfully mount the SD card, but the speed of reading, writing and comparing data to the SD card is...
I often hear people say not to use tantalum capacitors, but no one can explain why. There are many opinions on Baidu, saying that when it is bad, the positive and negative poles will short-circuit or ...
