我用51都可以的,但stm32就不行,我的目的很简单,就让TFT显示出颜色就行,这是我的程序,让大家看看哪里不对: #include "stm32f10x_lib.h" #define GPIOA_LCD_CS GPIO_Pin_1 #define GPIOA_LCD_RS GPIO_Pin_2 #define GPIOA_LCD_WR GPIO_Pin_3 #define GPIOA_LCD_RD GPIO_Pin_8 #define GPIOA_LCD_RESET GPIO_Pin_11 #define ILI9325_CS_LOW() GPIO_ResetBits(GPIOA,GPIOA_LCD_CS) #define ILI9325_CS_HIGH() GPIO_SetBits(GPIOA,GPIOA_LCD_CS) #define ILI9325_RS_LOW() GPIO_ResetBits(GPIOA,GPIOA_LCD_RS) #define ILI9325_RS_HIGH() GPIO_SetBits(GPIOA,GPIOA_LCD_RS) #define ILI9325_WR_LOW() GPIO_ResetBits(GPIOA,GPIOA_LCD_WR) #define ILI9325_WR_HIGH() GPIO_SetBits(GPIOA,GPIOA_LCD_WR) #define ILI9325_RD_LOW() GPIO_ResetBits(GPIOA,GPIOA_LCD_RD) #define ILI9325_RD_HIGH() GPIO_SetBits(GPIOA,GPIOA_LCD_RD) #define ILI9325_RESET_LOW() GPIO_ResetBits(GPIOA,GPIOA_LCD_RESET) #define ILI9325_RESET_HIGH() GPIO_SetBits(GPIOA,GPIOA_LCD_RESET) void RCC_Configuration(void) { ErrorStatus HSEStartUpStatus; /* RCC system reset(for debug purpose) */ RCC_DeInit(); /* Enable HSE */ RCC_HSEConfig(RCC_HSE_ON); /* Wait till HSE is ready */ HSEStartUpStatus = RCC_WaitForHSEStartUp(); if(HSEStartUpStatus == SUCCESS) { /* Enable Prefetch Buffer */ FLASH_PrefetchBufferCmd(FLASH_PrefetchBuffer_Enable); /* Flash 2 wait state */ FLASH_SetLatency(FLASH_Latency_2); /* HCLK = SYSCLK */ RCC_HCLKConfig(RCC_SYSCLK_Div1); /* PCLK2 = HCLK */ RCC_PCLK2Config(RCC_HCLK_Div1); /* PCLK1 = HCLK/2 */ RCC_PCLK1Config(RCC_HCLK_Div2); /* PLLCLK = 8MHz * 9 = 72 MHz */ RCC_PLLConfig(RCC_PLLSource_HSE_Div1, RCC_PLLMul_9); /* Enable PLL */ RCC_PLLCmd(ENABLE); /* Wait till PLL is ready */ while(RCC_GetFlagStatus(RCC_FLAG_PLLRDY) == RESET) { } /* Select PLL as system clock source */ RCC_SYSCLKConfig(RCC_SYSCLKSource_PLLCLK); /* Wait till PLL is used as system clock source */ while(RCC_GetSYSCLKSource() != 0x08) { } } } void NVIC_Configuration(void) { #ifdef VECT_TAB_RAM /* Set the Vector Table base location at 0x20000000 */ NVIC_SetVectorTable(NVIC_VectTab_RAM, 0x0); #else /* VECT_TAB_FLASH */ /* Set the Vector Table base location at 0x08000000 */ NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0); #endif } void GPIO_Configuration(void) { RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOB, ENABLE); GPIO_InitTypeDef GPIO_InitStructure; GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable, ENABLE); /* Configure PD.7--PD.11 as Output push-pull */ GPIO_InitStructure.GPIO_Pin = GPIOA_LCD_CS | GPIOA_LCD_RS | GPIOA_LCD_WR | GPIOA_LCD_RD | GPIOA_LCD_RESET ; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_2MHz; GPIO_Init(GPIOA, &GPIO_InitStructure); /* Configure PE.00 -- PE.15 as Output push-pull */ GPIO_InitStructure.GPIO_Pin = GPIO_Pin_All; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_2MHz; GPIO_Init(GPIOB, &GPIO_InitStructure); } //延时功能函数 void ILI9325_Delay (int nCount) { int i; for (i = 0; i < nCount * 250; i++) { } } void ILI9325_WriteData(unsigned int Data) { ILI9325_RS_HIGH(); ILI9325_RD_HIGH(); GPIO_Write(GPIOB,Data); ILI9325_WR_LOW(); ILI9325_WR_HIGH(); } void ILI9325_WriteCom(unsigned int Data) { ILI9325_RS_LOW(); ILI9325_RD_HIGH(); GPIO_Write(GPIOB,Data); ILI9325_WR_LOW(); ILI9325_WR_HIGH(); } void Address_set(unsigned int x1,unsigned int y1,unsigned int x2,unsigned int y2) { ILI9325_WriteCom(0x0020);ILI9325_WriteData(x1); ILI9325_WriteCom(0x0021);ILI9325_WriteData(y1); ILI9325_WriteCom(0x0050);ILI9325_WriteData(x1); ILI9325_WriteCom(0x0052);ILI9325_WriteData(y1); ILI9325_WriteCom(0x0051);ILI9325_WriteData(x2); ILI9325_WriteCom(0x0053);ILI9325_WriteData(y2); ILI9325_WriteCom(0x0022); } void ILI9325_Init(void) { ILI9325_RESET_HIGH(); ILI9325_Delay(5); ILI9325_RESET_LOW(); ILI9325_Delay(5); ILI9325_RESET_HIGH(); ILI9325_Delay(5); ILI9325_CS_LOW(); ILI9325_WriteCom(0x00E5); ILI9325_WriteData(0x78F0); // set SRAM internal timing ILI9325_WriteCom(0x0001); ILI9325_WriteData(0x0100); // set SS and SM bit ILI9325_WriteCom(0x0002); ILI9325_WriteData(0x0700); // set 1 line inversion ILI9325_WriteCom(0x0003); ILI9325_WriteData(0x1030); // set GRAM write direction and BGR=1.

STM32和51是不一样的,建议你好好的看看STM的IO口操作、总线操作。
我已经做过一些stm32的IO口的实验了

你显示不了颜色,主要的原因是IO管脚的操作。
没有启动AFIO,所以PB3和PB4并不是I/O。

其他脚也一一检查一下。
