Real-time data acquisition firmware for the STM32F746G-DISCO.

The project is being developed as an embedded systems portfolio project and as the basis for a bachelor's thesis on real-time data acquisition.

Hardware

• STM32F746G-DISCO
• STM32F746NGH6 (ARM Cortex-M7)
• ST-LINK/V2-1
• ST-LINK Virtual COM Port

Toolchain

• STM32CubeMX
• CMake + Ninja
• arm-none-eabi-gcc
• OpenOCD

Current implementation

• Board bring-up and ST-LINK flashing
• GPIO input/output
• USART1 polling TX/RX
• EXTI11 button interrupt
• TIM6 hardware time base
• TIM6 update interrupt
• ADC polling
• TIM6-triggered ADC sampling
• DMA-based ADC acquisition

Planned acquisition pipeline

TIM6 → ADC → DMA → RAM buffer → packetization → host interface

Roadmap

• ADC polling
• Hardware-triggered ADC
• Circular / double-buffered DMA
• Block timestamps
• Binary transport protocol
• CRC and error counters
• Host-side Python receiver and visualization
• Sampling-rate / throughput / data-loss measurements
