32 stm32外設篇lcd彩色屏顯示漢字英文數(shù)字程序設計

在LCD液晶屏上，把要顯示的漢字、英文、數(shù)字、圖案等所要經(jīng)過的像素點改變成與背景色不同的顏色，的眼睛就會看到想要得到的效果。這是實現(xiàn)的原理，如果要想實現(xiàn)LCD液晶屏的顯示，剛的目的是實用軟件驅(qū)動LCD液晶屏顯示， 省了很大部分的工作，下面介紹一下這款軟件，并使用它獲取字模代碼。在隨機光盤中有這款軟件具置是，《外設篇18.LCD彩色液4.32.1PCtoLD200214.32.1PCtoLD2002在工具條中點擊圖標進入設置界面“圖4.32.2下面來取字模型。在輸入?yún)^(qū)輸入漢字“眾”，點擊“生成字模”按4.32.3PCtoLD2002取字模型軟件使用”。4.32.3PCtoLD2002 40位的插座產(chǎn)生電氣連接。具體的引腳規(guī)定在《4.29STM32外設篇-LCD彩色液晶屏工作原理》中已經(jīng)做了詳細的介4.31.1Misc.c//中斷控制字（優(yōu)先級設置）庫函數(shù)stm32f10x_exti.c//外部中斷庫處理函數(shù)stm32f10x_tim.c//定時器庫處理函數(shù)stm32f10x_usart.c//串口通訊函數(shù)stm32f10x_fsmc.c//FSMC通訊函數(shù) #ifndef#ifndef#define lude"misc.h" lude"stm32f10x_exti.h" lude"stm32f10x_tim.h" lude"stm32f10x_spi.h" lude"stdio.h" lude"stm32_fsmc.h"stm32_fsmc externu8voidRCC_HSE_Configuration(void);voiddelay(u32nCount);//定義函數(shù)voiddelay_us(u32nus);//定義函數(shù)voiddelay_ms(u16nms);ifndef、#endifpbdata.h現(xiàn)錯誤提示。如果不加這兩條語句，當兩個文件同時調(diào)用pbdata文件時，會提示重復調(diào)用錯誤?！皊tm32_fsmc.h”和“l(fā)cd_ILI9325.h”是自定pbd下面是 ludeu8 {
