H730duino

Abstract

1. Introduction

Arduino form factor and software compatible board with giant cortex-m7 at 550MHz.

2. Objective

STM32H7 Arduino form factor and software compatible board

This project demonstrates how Arduino can be applied to a real-world Internet of Things (IoT) problem.

3. Key Features / Modules

• Hard real time capable CPU with predictable execution using tightly coupled memory for instruction and data.
• High speed and precision PWM suitable for motor control (BLDC, Stepper, DC).
• High resolution timing measure in capture mode for some pins.
• Arbitrary waveform generation in any GPIO using DMA without CPU intervention.
• High speed DACs suitable to generate analog signals up to 18MHz.
• Tow high speed 12 bits ADC suitable to capture up to 5MSPS in any channel.
• One high speed 16 bits ADC suitable to capture up to 7.5MSPSP
• Internal RAM with multiple block partitions enabling multiple peripheral access at same time without contention.
• External high density RAM up to 8 MB connected across 133MHz QSPI bus accessible in memory mapped mode or block device mode with on the fly encryption/decryption.
• External high density FLASH up to 16 MB connected across 133MHz QSPI bus accessible in memory mapped mode or block device mode with on the fly encryption/decryption.

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which microcontroller / board and sensors are used and why?
2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
3. Where is the sensor data stored and visualised?
4. How is power consumption managed?
5. How would you secure the device and its communication?
