STM32 open source four-axis-new version

Overview

1. Introduction

New version of STM32 quadcopter V3.0 project

Remote control project link for quadcopter: STM32 open source four-axis remote control

2. Function description:

1. Anonymous host computer PID parameter adjustment

2. Complementary filter attitude calculation, cascade PID

3.SI24R1 2.4G remote control, OLED real-time display of four-axis attitude, voltage return, and secondary development

4.STM32F103 main control, integrated MPU6050 attitude sensor, WS2812B full-color indicator light, etc., with reserved expandable interfaces

3. Finished product display:

4. PC PID parameter adjustment setting

Connection settings: 1. The port is the actual port 2. The baud rate is 460800

Connection Diagram:

PID parameter setting reference values:

5. Things to note:

1. The motor is a 716/720 coreless motor, the propeller is 55mm, and the battery is a 3.7V 1S lithium battery.

2. It is recommended to use the coreless cup motor and motor base of the 716 coreless motor and motor base of the punctual atomic small four-axis

3. Use the SH1.0 6P socket to bring out the programming and debugging interface. Program download requires an emulator (ST-LINK, etc.), and a serial port is reserved for connecting to the host computer for PID parameter adjustment.

4. Users need to have a certain knowledge of electronics and quadcopter related knowledge. The project does not involve welding and downloading a program before flying. It requires power distribution, PID parameter adjustment, etc.

5. For issues other than PCB engineering, watch Xiao Ma’s open source four-axis learning video: Xiao Ma’s DragonFly four-axis STM32 microcontroller course , a complete tutorial for four-axis beginners

6. Electronic amateurs cannot guarantee the standardization of PCB layout design. The design needs to be improved. No other problems have been found during use. If you have any questions, you can leave a message in the comment area below.

MSP430F5438 Development Board
If you want to group buy boards, you have to post. Haha. It's interesting.I bought an MSP430F5438 board two months ago. Who knew that I would fall in love with TI and 430 from then on. ^^I personally
PT4115 Four-channel PWM dimming
[color=rgb(68, 68, 68)][backcolor=transparent][font=Tahoma,]Hi everyone, this is a PWM four-way dimming module I made using PT4115, but as long as it is connected to 24V and GND, without PWM wave inpu
msgQreceive returns error, what does it mean?
Does it mean that there is no data in the queue, or is there some other error? What usually causes this? Thanks a lot
What to do? The PLL cannot lock
Have you ever had trouble trying to get a phase-locked loop (PLL) to lock? Rash judgments can prolong the debugging process and make it more tedious. The debugging process can be made much simpler by
