最小 STM32 TimerInterrupt_Generic PlatformIO / Arduino 定时器中断闪烁示例

***注意：***如果你需要更多灵活性，请参见最小 STM32 HardwareTimer PlatformIO / Arduino 定时器中断闪烁示例，其中我们展示了如何使用 HardwareTimer 而不是 TimerInterrupt_Generic。注意 TimerInterrupt_Generic 内部使用 HardwareTimer。

这是一个在 PlatformIO / Arduino 上使用 TimerInterrupt_Generic 库使用定时器中断的最小示例，该库在 Olimex E407 上运行。它几乎可以在任何 STM32 处理器上运行，但你可能需要将 PC13 调整为连接到 LED 的引脚。该示例将每秒闪烁一次 LED。

timer_interrupt_example.cpp

#include <Arduino.h>
#include <TimerInterrupt_Generic.h>

STM32Timer tim1(TIM1);
bool ledOn = false;

void OnTimer1Interrupt() {
    ledOn = !ledOn;
    digitalWrite(PC13, ledOn ? LOW : HIGH);
}

void setup() {
    pinMode(PC13, OUTPUT);
    // 启用 TIM4

    tim1.attachInterruptInterval(500000, OnTimer1Interrupt);
}

void loop() {
}

#include <Arduino.h>
#include <TimerInterrupt_Generic.h>

STM32Timer tim1(TIM1);
bool ledOn = false;

void OnTimer1Interrupt() {
    ledOn = !ledOn;
    digitalWrite(PC13, ledOn ? LOW : HIGH);
}

void setup() {
    pinMode(PC13, OUTPUT);
    // 启用 TIM4

    tim1.attachInterruptInterval(500000, OnTimer1Interrupt);
}

void loop() {
}

Now add

platformio_lib_deps.ini

lib_deps =
    khoih.prog/TimerInterrupt_Generic @ ^1.7.0

lib_deps =
    khoih.prog/TimerInterrupt_Generic @ ^1.7.0

到你的 platformio.ini。我的完整 platformio.ini 如下所示：

platformio_olimex_e407.ini

[env:olimex_e407]
platform = ststm32
board = olimex_e407
framework = arduino
lib_deps =
    khoih.prog/TimerInterrupt_Generic @ ^1.7.0

[env:olimex_e407]
platform = ststm32
board = olimex_e407
framework = arduino
lib_deps =
    khoih.prog/TimerInterrupt_Generic @ ^1.7.0
