Regarding the development of uPSd3234 chip, I use an 80pin chip with external memory interface, and it also has main Flash and secondary Flash inside. I use Keil to develop. I configure P1 and P3 acco
I used stm32 to send pwm to A3947 to control the stepper motor. I didn't use optocoupler isolation. I directly connected the GND of the microcontroller to the GND of the DC 24V, because I needed to us
In embedded development, some basic skills are required. In fact, these skills are relatively low-level. First of all, you need to master a language, C. With C as a foundation, you are basically halfw
The power factor correction (PFC) circuit and inverter circuit in telecom rectifiers and server power supply units (PSUs) need to detect the current signal on the high voltage side to the controller o
