嵌入式开发板显示爱心的代码

嵌入式开发板上显示爱心通常涉及到硬件控制（如LED灯或LCD屏幕）结合简单的编程语言，比如C/C++或汇编语言。这里以LED矩阵为例，展示一个基本的心形图案代码：

#include <xc.h> // assuming a microcontroller like PIC

void display_heart() {
    const int heart[] = { // LED matrix pattern (0 is off, 1 is on)
        0, 0, 0, 0, 0,
        0, 1, 1, 1, 0,
        0, 1, 0, 1, 0,
        0, 1, 1, 1, 0,
        0, 0, 0, 0, 0
    };

    for(int row = 0; row < sizeof(heart) / sizeof(int); ++row) {
        for(int col = 0; col <= row; ++col) {
            PORTBbits.RBbits.RB7 = heart[row * 5 + col]; // assuming a 5x5 LED matrix with RB7 as the top-left pixel
        }
        __delay_ms(100); // adjust delay time to control the animation speed
    }
}

int main(void) {
    TRISB = 0xFF; // set all PORTB pins as output
    while(1) {
        display_heart();
        PORTB = 0; // turn off all LEDs after showing the heart
    }
}
