stc89c52rc motor control

Overview

# The
main control system consists of stc89c52rc (LQFP-44 package), and the power supply interface is type-c. The serial port download

pin button is led out in an interrupt mode, and a capacitor hardware debounce circuit is added.

The screen uses a 0.96-inch ssd1306 black and white OLED screen commonly seen on Taobao, and uses IIC to communicate with the microcontroller.

The motor driver uses mx1508 dual-channel DC motor driver, and the driver uses an ams1117 for power supply, which is more than enough to drive the n20 motor.
# Working principle:
The microcontroller timer generates a pwm signal to control the mx1508 drive motor. The three buttons are phased and connected to the external interrupt port of the microcontroller to interrupt and read the key value. At the same time, the current motor working status is displayed on the OLED screen. ![IMG_3411.JPG]

Since the peripheral driver under WInCE runs in user mode, then...
I have never written a driver program under WinCE, and I only have a little basic knowledge of WDM under 2000. Since the peripheral driver program under WinCE runs in user mode, can the application pr
Are there any PIC related reference designs?
PIC seems to be rarely used. Why is it not easy to use and why do people not want to use it? Does anyone have PIC related reference designs, such as software, design videos, etc. that can be downloade
