RA8876和RA8877芯片自建字庫的調(diào)用方法如下：

首先需要使用提取字模軟件生成所需文字字庫的頭文件并將其添加到工程，
包含頭文件

#include

#include "stm32f10x.h"

#include "stdlib.h"

#include

#include "delay.h"

#include "UserDef.h"

 

#include "RA8876.h"

#include "RA8876_MCU_IF.h"

#include "RA8876_API.h"

#include "UserFontROM.h"

添加調(diào)用下列函數(shù) 
此函數(shù)列舉了8x16，16x16，16x24，24x24，16x32，32x32字體尺寸的調(diào)用
在下面的應用例程中也都一 一展示了顯示效果
