二、STemWin的LCD接口介绍
移植STemWin有两种方法，
第一种：用户接口，
在LCDConf_FlexColor_Template.c 中的LCD_X_Config函数中的设置为
GUI_DEVICE_CreateAndLink(&GUIDRV_Template_API, GUICC_M565, 0, 0);
1
第二种，STemWin接口
GUI_DEVICE_CreateAndLink(GUIDRV_FLEXCOLOR, GUICC_M565, 0, 0);
本例程主要介绍第一种接口的使用方法。
雅特力AT32F403A工程准备
四、雅特力AT32F403A的LCD调试。
本例程STemWin用的是用户接口，所以要先调试好LCD，准备好三个函数
1.第一个画点函数：
LCD_DrawPoint(u16 x,u16 y,u16 color);
1
2.第二个读点函数：
u16LCD_ReadPoint(u16 x,u16 y);
1
3.第三个填充函数：
void LCD_Fill(u16 xsta,u16 ysta,u16 xend,u16 yend,u16 color); 五、STemWin文件移植
1.在雅特力AT32F403A工程中添加以下文件
六、STemWin文件修改
1.LCDConf_FlexColor_Template.c
修改现实屏大小
#define XSIZE_PHYS320+1 // To be adapted to x-screen size
#define YSIZE_PHYS240+1 // To be adapted to y-screen size
修改用户接口
void LCD_X_Config(void)
{
//GUI_DEVICE * pDevice;
//CONFIG_FLEXCOLOR Config = {0};
//GUI_PORT_API PortAPI = {0};
//
// Set display driver and color conversion
//设定用户接口模式
GUI_DEVICE_CreateAndLink(&GUIDRV_Template_API, GUICC_M565, 0, 0);
//
// Display driver configuration, required for Lin-driver
//
LCD_SetSizeEx (0, XSIZE_PHYS , YSIZE_PHYS);
LCD_SetVSizeEx(0, VXSIZE_PHYS, VYSIZE_PHYS);
////
//// Orientation
////
//Config.Orientation = GUI_SWAP_XY | GUI_MIRROR_Y;
//GUIDRV_FlexColor_Config(pDevice, &Config);
////
//// Set controller and operation mode
////
//PortAPI.pfWrite16_A0= LcdWriteReg;
//PortAPI.pfWrite16_A1= LcdWriteData;
//PortAPI.pfWriteM16_A1 = LcdWriteDataMultiple;
//PortAPI.pfReadM16_A1= LcdReadDataMultiple;
//GUIDRV_FlexColor_SetFunc(pDevice, &PortAPI, GUIDRV_FLEXCOLOR_F66708, GUIDRV_FLEXCOLOR_M16C0B16);
}
2.GUIDRV_Template.c
这个文件要修改三个函数
第一个加入LCD_DrawPoint(x,y,PixelIndex);：static void _SetPixelIndex(GUI_DEVICE * pDevice, int x, int y, int PixelIndex) {
//
// Convert logical into physical coordinates (Dep. on LCDConf.h)
//
#if (LCD_MIRROR_X == 1) || (LCD_MIRROR_Y == 1) || (LCD_SWAP_XY == 1)
int xPhys, yPhys;
xPhys = LOG2PHYS_X(x, y);
yPhys = LOG2PHYS_Y(x, y);
#else
#define xPhys x
#define yPhys y
#endif
GUI_USE_PARA(pDevice);
GUI_USE_PARA(x);
GUI_USE_PARA(y);
GUI_USE_PARA(PixelIndex);
{
//
// Write into hardware ... Adapt to your system
//
// TBD by customer...
//
LCD_DrawPoint(x,y,PixelIndex);
}
#if (LCD_MIRROR_X == 0) && (LCD_MIRROR_Y == 0) && (LCD_SWAP_XY == 0)
#undef xPhys
#undef yPhys
#endif
}
第二个加入PixelIndex = LCD_ReadPoint(x,y);：static unsigned int _GetPixelIndex(GUI_DEVICE * pDevice, int x, int y) {
unsigned int PixelIndex;
//
// Convert logical into physical coordinates (Dep. on LCDConf.h)
//
#if (LCD_MIRROR_X == 1) || (LCD_MIRROR_Y == 1) || (LCD_SWAP_XY == 1)
int xPhys, yPhys;
xPhys = LOG2PHYS_X(x, y);
yPhys = LOG2PHYS_Y(x, y);
#else
#define xPhys x
#define yPhys y
#endif
GUI_USE_PARA(pDevice);
GUI_USE_PARA(x);
GUI_USE_PARA(y);
{
//
// Write into hardware ... Adapt to your system
//
// TBD by customer...
//
PixelIndex = LCD_ReadPoint(x,y);
}
#if (LCD_MIRROR_X == 0) && (LCD_MIRROR_Y == 0) && (LCD_SWAP_XY == 0)
#undef xPhys
#undef yPhys
#endif
return PixelIndex;
}
第三个加入LCD_Fill(x0,y0,x1,y1,LCD_COLORINDEX);：
static void _FillRect(GUI_DEVICE * pDevice, int x0, int y0, int x1, int y1)
{
LCD_Fill(x0,y0,x1,y1,LCD_COLORINDEX);
//LCD_PIXELINDEX PixelIndex;
//int x;
//PixelIndex = LCD__GetColorIndex();
//if (GUI_pContext->DrawMode & LCD_DRAWMODE_XOR) {
// for (; y0 <= y1; y0++) {
// for (x = x0; x <= x1; x++) {
// _XorPixel(pDevice, x, y0);
// }
// }
//} else {
// for (; y0 <= y1; y0++) {
// for (x = x0; x <= x1; x++) {
// _SetPixelIndex(pDevice, x, y0, PixelIndex);
// }
// }
//}
}
3.GUIConf.c
修改内存大小：
#define GUI_NUMBYTES40*1024
该处使用的url网络请求的数据。
4.at32f403a_407_int.c
修改systick定时器中断：
extern __IO int32_t OS_TimeMS;
void SysTick_Handler(void)
{
OS_TimeMS++;
if(OS_TimeMS%100 == 0)
{
LED2_BL;//加个LED指示一下
}
}
5.main.c测试
代码如下（示例）：
#include "at32f403a_407_clock.h"
#include "Drv_Delay.h"
#include "Drv_Uart.h"
#include "Drv_Led.h"
#include "Drv_LCD.h"
#include "WM.h"
#include "GUI.h"
#include "GUIDEMO.h"
intmain(void)
{
system_clock_config();
uart_print_init(115200);
LCD_Init();
LCD_Back(BLUE);
systick_clock_source_config(SYSTICK_CLOCK_SOURCE_AHBCLK_NODIV);
SysTick_Config(system_core_clock / 1000U); //开启Systick中断
crm_periph_clock_enable(CRM_CRC_PERIPH_CLOCK, TRUE); //打开CRC时钟
WM_SetCreateFlags(WM_CF_MEMDEV); //允许存储器
GUI_Init(); //初始化GUI
GUI_SetBkColor(GUI_BLUE); //设置背景色为蓝色
GUI_SetColor(GUI_WHITE); //设置前景色为白色
GUI_Clear(); //清屏
GUI_SetFont(&GUI_Font8x16x3x3); //字体设置
GUI_DispStringAt("Hello World!",20,50);
while(1){}
}
