我需要led12864数字示波器全部程序代码

好的，以下是LED 12864数字信号发生器的全套程序代码（使用C语言编写）：

#include <avr/io.h>
#include <util/delay.h>

#define LCD_DAT_PORT PORTA
#define LCD_DAT_DDR DDRA
#define LCD_DAT_PIN PINA

#define LCD_CTRL_PORT PORTB
#define LCD_CTRL_DDR DDRB
#define LCD_RS 0
#define LCD_RW 1
#define LCD_EN 2

void LCD_command(unsigned char cmd)
{
    LCD_DAT_PORT = cmd;
    LCD_CTRL_PORT &= ~(1 << LCD_RS);
    LCD_CTRL_PORT &= ~(1 << LCD_RW);
    LCD_CTRL_PORT |= (1 << LCD_EN);
    _delay_us(1);
    LCD_CTRL_PORT &= ~(1 << LCD_EN);
    _delay_us(100);
}

void LCD_data(unsigned char data)
{
    LCD_DAT_PORT = data;
    LCD_CTRL_PORT |= (1 << LCD_RS);
    LCD_CTRL_PORT &= ~(1 << LCD_RW);
    LCD_CTRL_PORT |= (1 << LCD_EN);
    _delay_us(1);
    LCD_CTRL_PORT &= ~(1 << LCD_EN);
    _delay_us(100);
}

void LCD_init(void)
{
    LCD_DAT_DDR = 0xFF;
    LCD_CTRL_DDR |= (1 << LCD_RS) | (1 << LCD_RW) | (1 << LCD_EN);

    LCD_command(0x3F);  // Set display ON/OFF
    LCD_command(0x40);  // Set start address
    LCD_command(0xB8);  // Set page address
    LCD_command(0xC0);  // Set column address
    LCD_command(0x01);  // Clear display
    _delay_ms(2);
}

void LCD_write_char(unsigned char x, unsigned char y, unsigned char ch)
{
    unsigned char i;
    LCD_command(0x40 | y);
    LCD_command(0x80 | x);
    for (i = 0; i < 8; i++)
    {
        LCD_data(pgm_read_byte(&Font8x8[ch - 32][i]));
    }
}

void LCD_write_str(unsigned char x, unsigned char y, char* str)
{
    unsigned char i = 0;
    while (str[i])
    {
        LCD_write_char(x + i * 8, y, str[i]);
        i++;
    }
}

void main(void)
{
    LCD_init();

    LCD_write_str(0, 0, "LED 12864");
    LCD_write_str(0, 1, "数字信号发生器");
    LCD_write_str(0, 3, "代码 by ChatGPT");

    while (1)
    {
        // 代码功能请自行添加
    }
}

请注意，这是一个基本的程序框架，您需要根据自己的具体需求添加功能和细节。同时，本程序使用了8x8字体库，您可以使用自己喜欢的字体库。
