From the project

This Firmware was developed as an extension of Ti's Sensored close-loop BLDC motor control using MSP430. Ti's application firmware for MSP430 has been modified for STM32F103 Series MCU's.

This firmware was developed by Rahul (rep owner) https://github.com/g-rahul RVCE July 2020

Target-STM32F103C8T6 IDE- MDK Keil uVision 5

The author would like to credit the orignal code developer on whose idea this code is based upon Bhargavi Nisarga Texas Instruments Inc. Dec 2010 Built with IAR Version:4.2 and CCS v4.2

More information on Ti's MSP430 application can be found at https://www.ti.com/lit/an/slaa503/slaa503.pdf?ts=1596031062777&ref_url=https%253A%252F%252Fwww.google.com%252F & http://www.ti.com/lit/zip/slaa503.

Sensored-3-P-BLDC-Closed-Loop-V1: common questions

What microcontroller does the Sensored-3-P-BLDC-Closed-Loop-V1 use?

The Sensored-3-P-BLDC-Closed-Loop-V1 is built around the STM32Bluepill, from the STM32 family.

How big is the Sensored-3-P-BLDC-Closed-Loop-V1 PCB?

The Sensored-3-P-BLDC-Closed-Loop-V1 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sensored-3-P-BLDC-Closed-Loop-V1?

114 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sensored-3-P-BLDC-Closed-Loop-V1 design files?

From the g-rahul/Sensored-3-P-BLDC-Closed-Loop-V1 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Sensored-3-P-BLDC-Closed-Loop-V1 design in my own project?

The repository has no license, so all rights stay with g-rahul. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Sensored-3-P-BLDC-Closed-Loop-V1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
