怎样申请网站域名和空间,宿州建设银行网站,p2p网站方案,wordpress主题的安装教程1、BK7231有2M flash#xff0c;可以保存1个16*16汉字字库 2、驱动1个8位并口屏#xff0c;将字库中的汉字中显示出来 一、将gb2312_80.bin打包到烧录镜像中。

1、bk7231u_rtt_sdk\OTAPackage\beken_packager中修改config.json文件
{magic: RT-Thread,version: 0.1,count: 3,section: [{firmware: bootloader_bk7231_ottime_v2.0.bin,version: 0.1.3,partition: bootloader,start_addr: 0x00000000,size: 68K},{firmware: ../../rtthread.bin,version: 0.1.15,partition: app,start_addr: 0x00011000,size: 1156K},{firmware: gb2312_80.bin,version: 0.0.2,partition: romfs,start_addr: 0x000D0000,size: 239K}]
} 其中gb2312_80.bin是16*16汉字GB2312库可以通过高通字库软件生成。
这样再运行beken_packager.exe可以把字库文件打包到用于下载FLASH的镜像文件中。
字库文件的起始地址是0xD0000。

1、这个字库偏移的计算公式 if(GBH0xb0) { offset((GBH-0xa7)*94GBL-0xa1)*34; }else { offset((GBH-0xa1)*94GBL-0xa1)*34; } 为什么是*34不是*32可能是打包bin的时候每32字节增加了2个字节校验位或者什么。对那个打包文件不太懂反正跳过那多的2个字节就好了。
2、 drv_lcd.c、drv_lcd.h文件放在bk7231u_rtt_sdk\drivers中。
3、msh中键入lcd运行 msh /lcd msh / 4、 user_app_start(void)中加入lcd_sample()可以在开机后直接驱动LCD显示 extern int lcd_sample(void); void user_app_start(void) { rt_hw_wdg_start(0, NULL); lcd_sample(); //前面加extern } 5、**\bk7231u_rtt_sdk\beken378\app\config中sys_config.h需做如下修改 #define CFG_JTAG_ENABLE 0 这样JTAG的pin复用为普通GPIO 用于LCD驱动。
