Looking at the chip manual, I wrote a program to generate PWM to control the brightness of the LED. The purpose is to change the duty cycle of PWM when the button is pressed. The button uses an extern...
I encountered a problem today. I used ICL7660 to convert +5V voltage to -5V to power two op amps. When there is no op amp in the circuit or one op amp is connected, 7660 can normally convert +5V to -5...
I use two STM32F4 SPI1 bidirectional communication, and want to realize that the master SPI sends 1024 data, and the slave SPI replies an ack when it receives it. When the master SPI receives this ack...
