Abstract: The principle of the pulse width modulation current mode controller NCP1200A for low power general offline power supply is introduced, and the advantages of this controller are further illus...
The function for setting the module interrupt priority in the Systick module initialization configuration function (Systick_config) is:
NVIC_SetPriority((SysTick_IRQn, (1__NVIC_PRIO_BITS) - 1);The par...
In many control situations, it is necessary to divide the signal. The following uses the two-frequency division program shown in Figure 5-16 as an example to illustrate how PLC achieves frequency divi...
