This repository contains firmware to drive a 36V Electronic Speed Controller (ESC) for a DC motor. This project has been tested to handle a 3A load without issue. Motor speed is monitored and controlled using a hall effect sensor and PID feedback.
Driver code for the H-Bridge circuit is found in /Core/Src. The files main.c, H_bridge.c, user_input.c and rpm_feedback.c contain custom code developed for this project.
Images of the project are found below, along with an operation guide.
Load Testing
- Construct circuit shown in the latest schematic version with the parts listed in the expense report.
- Optional: Order two PCBs using the files in /H_Bridge_KiCAD and /STM32_KiCAD.
- Program STM32 chip with the code, found in this repository, using SWD.
- Power on circuit and controller.
- For safety, the device starts in an OFF state. Shift the direction switch once to begin operation.
- Use the potentiometer to set a desired speed within the range of 60 to 200 RPM.
