写一段代码可以使用stm32f103驱动tftlcd显示屏显示120*120图片
时间: 2024-03-25 18:40:07 浏览: 40
好的,以下是一个简单的示例代码:
```c
#include "stm32f10x.h"
#include "lcd.h"
#include "image.h" // 假设image.h中包含要显示的图片数据
int main(void)
{
LCD_Init(); // 初始化LCD
LCD_Clear(WHITE); // 清屏
// 在(0, 0)位置显示120*120的图片
LCD_ShowPicture(0, 0, 120, 120, (uint16_t *)image_data);
while(1)
{
// 程序循环
}
}
```
需要注意的是,这里的`image_data`是一个数组,包含了要显示的图片数据。具体的数据格式和排列方式需要根据你使用的LCD屏幕型号而定。在实际开发中,你需要先了解你所使用的LCD屏幕的数据手册,以正确地配置和驱动它。

STM32F103使用TFTLCD显示屏需不需要配置I2C
通常情况下,STM32F103系列MCU的GPIO引脚不支持直接的I2C功能。而是通过软件模拟实现I2C通信协议,这种方式被称为"Bit-banging"。因此,如果您要使用STM32F103MCU驱动TFTLCD显示屏,通常不需要配置I2C。
相反,常见的TFTLCD显示屏通常使用SPI(串行外设接口)或8080并行接口进行通信。您需要配置STM32F103的GPIO引脚作为SPI或并行接口的时钟、数据线、片选等信号线,并编写相应的SPI或并行接口驱动程序来控制和通信。
请注意,具体的配置和编程过程可能会因您所使用的具体显示屏型号和库函数而有所不同。建议参考您所使用的TFTLCD显示屏的规格和驱动程序文档,并查阅相关的示例代码和资料,以便正确地配置和驱动显示屏。
