1 IntroductionThe frequency divider is the basic unit in the phase-locked loop circuit and is the unit circuit that works at the highest frequency in the phase-locked loop. Traditional frequency divid...
Hello everyone! I want to use the LT3480 switching regulator, with an input of 25V, an output of 3.3V, and an output current of 0.3A. I checked the table (efficiency vs. load current) and found that t...
With its sports car looks, airline-like instrument panel display and quiet, smooth start, it's no surprise that the Toyota Prius gasoline/electric hybrid is the fastest-selling vehicle in its class. (...
I use the functions in the math library. When the program code is small, it runs normally.However, if the program code is large, such as 0x2000, calling the functions in the math librarywill cause the...
I chose an 8M crystal ADC as the main frequency and wanted to sample with 32768hz ACLK, but I couldn't choose it. It always runs at 8m. The code is as follows WDTCTL = WDTPW | WDTHOLD; // Disable the ...
