AT8222 DC Motor Drive Test

Overview

Overall Board

Usage Instructions:
1. Detailed Wiring :
OUT1, OUT2 ---> Connect to motor;
IN1, IN2 --------> Connect to input level signal or control board PWM signal (see control logic section below for details);
VR -------------> Connect to reference voltage (input range 0.5-4V, voltage selection see the final formula);
GND -------------> Connect to signal and drive ground (both must share a common ground!);
HV ------------> Connect to motor drive voltage (5.5-24V, select according to the motor).
2. Related Wiring Details:
Control Logic

Maximum Current Limiting Formula:
(Vref is the input reference voltage, Risen is the 0.15Ω resistor on the board. When not limiting current, Vref can be any voltage from 0.5-4V, and Risen is shorted to ground!)
For example: when Vref=1.5V, R=0.15Ω, then Imax=1.5/(10x0.15)=1A

Ask about CCS.
In CCS SETUP, select simulator, copy the entire folder of the EEWORLDSDRAM example to myproject, then open the project of this example, rebuild all, load .out, go main, all are OK, but run does not wo
Can TM4C123GH6PZI connect to a 7-inch touch screen?
I have seen it connected to a 3.2-inch touch screen, but I don't know if it can drive a 7-inch one. I hope those who have done it before or not can give me some advice.
Three-terminal voltage regulator overheating problem
I have recently built a circuit, where the 12V power supply is stabilized by LM1117-3.3 to 3.3V before supplying the DSP chip. Because the normal full working current is 90MA, the voltage regulator is
