Crate blackbox_rs 

Board support crate for the Blackbox board (STM32H743XI, rev.Y).

init brings the whole board up at its design clocks and returns a Board holding ready-to-use drivers. Each subsystem also stands alone in its own module if you want to wire a custom subset.

#[embassy_executor::main]
async fn main(_spawner: Spawner) -> ! {
    let mut board = blackbox_rs::init().await;
    loop {
        let touch = board.touch.poll(&mut board.i2c);
        board.display.target().clear(Rgb565::BLACK).ok();
        board.display.swap().await;
    }
}

Modules

audio

Stock Blackbox audio bring-up: SAI1_A + SAI1_B + SAI2_A, raw registers.

buttons

13 active-low buttons with board pull-ups (README §buttons).

clock

Board clock tree (README §RCC).

cpu

CPU caches, MPU regions and SYSCFG fixes that must run before the peripherals.

display

LTDC display: 320×240 RGB565 panel, vblank-synced double buffer, plus panel power and backlight. Framebuffers live in SDRAM (coherent with the LTDC DMA — D-cache is off).

knobs

4 endless rotary encoders, read through ADC1 (README §knobs).

leds

11 active-high indicator LEDs (README §LEDs).

sdram

External SDRAM: 2× ISSI IS42S16160J (32-bit bus) on FMC bank1, 64 MiB @ 0xC000_0000.

touch

Goodix GT9147 capacitive touch over I2C1 (README §touch).

Structs

Board

The fully initialized board. Touch owns its handle to the shared I2C1 bus.

Irqs

Functions

init

Bring up clocks, CPU/MPU, SDRAM and every on-board peripheral, then start a 440 Hz tone.
