我正在研究 pic 微控制器编程，最近去了 lcd 制作了 2 个代码，一个在 mplab 中，另一个在 mikroc 中实际上都在 isis 中工作，但是当我真正尝试它时，只有 mikroc 代码在微控制器中工作我不知道实际上是什么是问题/为什么会发生这种情况我不认为这是硬件或软件代码，因为它是相同的电路并且两个代码都在 isis 中工作所以如果有人想查看代码，那么这里是：
微克：
// Lcd pinout settings
sbit LCD_RS at RC0_bit;
sbit LCD_EN at RC1_bit;
sbit LCD_D7 at RB7_bit;
sbit LCD_D6 at RB6_bit;
sbit LCD_D5 at RB5_bit;
sbit LCD_D4 at RB4_bit;
// Pin direction
sbit LCD_RS_Direction at TRISC0_bit;
sbit LCD_EN_Direction at TRISC1_bit;
sbit LCD_D7_Direction at TRISB7_bit;
sbit LCD_D6_Direction at TRISB6_bit;
sbit LCD_D5_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB4_bit;
void main() {
Lcd_Init();
Lcd_Cmd(_LCD_CLEAR); // Clear display
Lcd_Cmd(_LCD_CURSOR_OFF); // Cursor off
Lcd_Out(1, 3, "Hello!");
}
实验室：
主.c：
#include "config.h"
unsigned char CurvyObject[8] = { 0x01,0x02,0x04,0x08,0x10,0x11,0x1f,0x00 };
void main(){
TRISB = 0;
TRISC = 0;
send_command(0x38);
__delay_us(40);
send_command(0x01);
__delay_ms(1.75);
send_command(0x0C);
__delay_us(40);
moveto(0, 0, 0, 0, 0, 0, 0);
__delay_us(40);
write_character(70);
__delay_us(50);
write_character(97);
__delay_us(50);
write_character(100);
__delay_us(50);
write_character(121);
__delay_us(50);
while(1);
}
