Rust运行Stm32 Blink

用Rust语言编写Stm32F103c8t6程序

需要的设备

STM32f103c8t6单片机一个
ST-Link V2 仿真器
杜邦线
面包板 [可选]

需要安装的软件

shell

rustup target install thumbv7m-none-eabi

shell

sudo apt install openocd gdb-multiarch binutils-arm-none-eabi

先让项目跑起来 - blink Date: 2021-1-31

连接硬件 stm32 与stlink连接, 并将 stm32 boot-1 置 1 boot-0 置 1

在项目路径下运行指令,配置 gdb

shell

echo "set auto-load safe-path $(pwd)" >> ~/.gdbinit

新建一个rust项目,修改Cargo.toml 增加如下配置:

toml

[dependencies]
embedded-hal = "0.2.3"
nb = "0.1.2"
cortex-m = "0.6.2"
cortex-m-rt = "0.6.11"
# Panic behaviour, see https://crates.io/keywords/panic-impl for alternatives
panic-halt = "0.2.0"

[dependencies.stm32f1xx-hal]
version = "0.6.1"
features = ["rt", "stm32f103", "medium"]

在项目根路径添加如下文件

.cargo/config

[target.thumbv7m-none-eabi]
runner = 'gdb-multiarch'
rustflags = [
    "-C", "link-arg=-Tlink.x",
]

[build]
target = "thumbv7m-none-eabi"

memory.x

/* Linker script for the STM32F103C8T6 */
MEMORY
{
  FLASH : ORIGIN = 0x08000000, LENGTH = 64K
  RAM : ORIGIN = 0x20000000, LENGTH = 20K
}

.gdbinit

target remote :3333

monitor arm semihosting enable

# # send captured ITM to the file itm.fifo
# # (the microcontroller SWO pin must be connected to the programmer SWO pin)
# # 8000000 must match the core clock frequency

# # OR: make the microcontroller SWO pin output compatible with UART (8N1)
# # 2000000 is the frequency of the SWO pin

修改main.rs文件:

rust

//! Blinks an LED
//!
//! This assumes that a LED is connected to pc13 as is the case on the blue pill board.
//!
//! Note: Without additional hardware, PC13 should not be used to drive an LED, see page 5.1.2 of
//! the reference manual for an explanation. This is not an issue on the blue pill.
