PortentaH7_VFR

Portenta H7 "Visual Flight Radar"

STM32CubeIDE project

This project is not an Arduino/mbed sketch. It is native C-code (not C++), as a STM32CubeIDE project. It uses the STM HAL drivers, CMSIS FreeRTOS.

Project Purpose

use the PDM MICs in order to track airplanes (above my home)
Pan and Tilt the board (the MICs, with camera) to follow an airplane
focus camera (not yet used) to track an airplane

HW Requirements

Portenta H7 MCU module
Portenta H7 VisionShield: using ETH connection and PDM MICs on board
(optional) Breakout Board: using ETH and USB-A connection, external PDM MICs, I2C for IMU

Features of the project

it provides a UART shell via the USB-C connection, see "help" command there
running FreeRTOS
Network support: ETH (not WiFi), for web server running on MCU, UDP transfer, e.g. Audio via UDP, network commands to do SPI, I2C
using SDRAM: used for Pico-C scripts
Pico-C: a C-code interpreter (no compiler needed, write C-code scripts)
PDM MICs for Audio (on Vision Shield) to host (as VBAN, VB-Audio Voicemeeter) - via ETH network
two PWM channels for RC model servos
QSPI flash: used for man pages
SPI and I2C peripherals
USB-A on Breakout Board (for Audio, prepared for USB as external memory device, a second VCP UART)
use external PDM MIC on Breakout Board
I2C and command for 9-degree IMU sensor

Full Open Source

The project has all source code files, including the PMIC configuration, INT vectors, drivers, startup - not using any Arduino/mbed library.

Without or with Arduino Bootloader

Project (linker script) can be configured to use an external debugger and utilize the entire Flash ROM space (overwrite the Bootloader). Possible also to keep the Bootloader and flash MCU FW via command line.
