I lent my board to my classmate a few days ago. Today he told me that the LCD screen was burned when I was debugging. He said there was a burning smell when I was debugging. Later he saw white smoke c...
Class D amplifiers have better efficiency and thermal performance than Class AB amplifiers, but implementing a Class D amplifier still requires good electrical and thermal design practices. Most engin...
I made a servo driver board with stm32f103, that is, I made a minimum system, using timer 2 3 4 to generate PWM to control the servo. The delay program is fine during debugging, but it always has no e...
Now I need to sort 144 data in FPGA. In addition to bubble sort, I also use RAM to sort, because bubble sort consumes too many resources, and RAM sorting will cause some problems that cannot be solved...
