Liangshan School Intelligent Obstacle Avoidance Car

Overview

Based on the smart car motherboard produced by Liangshan School, its functions include obstacle avoidance, ranging, tracking, and Bluetooth communication. It has an ISP screen for easy debugging, an encoder interface, and can control the car PID, as well as lights and power indicators.

The motor drive of the car uses a dual-channel drive board controlled by the IR2104 chip. The left and right steering of the car relies on the differential speed of the motor. Due to the impact of the epidemic, many functions have not been perfected. Currently, only the obstacle avoidance function is implemented. , the functions will be gradually improved in the future.

The motherboard power supply circuit part

of the car uses a 7.8V model aircraft battery as the power supply. Jiangsu Changjing's CJ7805 linear voltage regulator is selected to convert the 7.8V voltage into the 5V power supply required by the Liangshan School and some peripherals. In addition, an electrolytic capacitor to improve the load capacity of the chip. Use the common AMS1117 to achieve step-by-step voltage reduction to power other peripherals.

C2000 Software Serial Interface (SCI) Implementation Method
The C2000 Piccolo series MCU chips generally integrate 1-2 hardware SCI (UART). Sometimes, due to cost or layout area considerations, only small packages or models with less resources can be selected,
Confused about using LMS811 PWM DOWN mode and UP_DOWM mode
I am confused. When using LMS811 PWM in DOWN mode and UP_DOWM mode, the data defined in the timer filling PWMGenPeriodSet(PWM_BASE, PWM_GEN_0, ulPeriod); are the same. According to my understanding, t
