根据 xargo,我的代码已成功构建,但目标中没有二进制文件,为什么?
According to xargo my code has built successfully, but there's no binary in target, why?
我是 Rust 的新手,所以如果我还不知道 lingo/tools,请原谅我。我正在尝试让 STM32F4 使 LED 闪烁,我认为代码是正确的,但是当我构建它时 xargo 不会生成二进制或任何类型的错误。我的代码是:
#![feature(proc_macro)] // <- IMPORTANT! Feature gate for procedural macros
#![no_std]
extern crate cortex_m;
extern crate cortex_m_rtfm as rtfm;
extern crate stm32f40x;
use cortex_m::peripheral::SystClkSource;
use rtfm::{app, Threshold};
app! {
device: stm32f40x,
resources: {},
tasks: {
SYS_TICK: {
path: toggle,
resources: [GPIOC],
},
},
}
fn init(p: init::Peripherals, _r: init::Resources) {
// TODO: initialize the GPIO
p.SYST.set_clock_source(SystClkSource::Core);
p.SYST.set_reload(8_000_000); // 1s?
p.SYST.enable_interrupt();
p.SYST.enable_counter();
}
fn idle() -> ! {
loop {
rtfm::wfi();
}
}
fn toggle(_t: &mut Threshold, r: SYS_TICK::Resources) {
**r.GPIOC.odr.modify(|r, w| w.odr13().bit(!r.odr13().bit()));
}

虽然在 target/ none 中生成了很多东西,但我可以将其闪存到板上。知道为什么吗?我的意思是,它必须是简单的东西,但我没有经验知道去哪里看。
在tutorial you were following, all of the examples are in an "examples" directory。您可以使用 --example
参数构建它们,如教程中所示:
xargo build --example hello
但是,如果这是您的主要程序,您需要将代码放在 "src/main.rs" 中,只允许:
xargo build
如果你有多个可执行文件,你可以。
