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...
