ROAR_Embedded

Embedded code running on the ROAR ESP32 chip

BLE+ SPEED

Parts required:

• Mini/Micro USB Wires supporting Data Transmission

• Jumper wires

• ESP32 Motherboard

• ROAR customized PCB Board

Procedure:

Google Doc: https://docs.google.com/document/d/1D5ydaaLVN3bytds7K1XcLaF4Gcsg35xMvoRSOgNlM3k/edit?usp=sharing

1. STEP1: Connect all the jumper wires according to the below config
2. STEP2: Plugin the USB wire into the laptop and the ESP-32-CAM-MB boardOn Platform IO, make sure the code compiles before uploading
3. STEP3: Upload, and when seeing “Connecting…..” in the terminal, press the RST on the ESP32-CAM-MB until the data is being transferred.
4. STEP4: Boom, you’re done!

A side note: connect the 5V to the + of throttle/steering is fine, but connecting it to the halleffect sensor +/- may risk frying the chip.

STEP 1:

This code is designed to be used with a custom PCB made for ROAR and intelligent racing. The wiring diagram to flash the PCB is as follows:

Notes:

It is highly recommended to use PlatformIO an IDE and dependency manager along with Visual Studio Code to Work on this project and properly manage dependencies. You can follow a Quick Start Installation Guide Here:

https://docs.platformio.org/en/latest/integration/ide/vscode.html

If you are new to PlatformIO or Arduino programming. For more resources and Tutorials see this helpful youtube tutorial playlist for ESP32 using PlatformIO

https://youtube.com/playlist?list=PLzvRQMJ9HDiQ3OIuBWCEW6yE0S0LUpWhGU

After opening the project in Visual Studio Code with PlatformIO

Step2: BUILD

you should see a SUCCESS message

Step3: UPLOAD

When you see Connecting … in the terminal output

Hold Down the RST Button on the ESP32-CAM-MB

Post upload you should see SUCCESS
