            如何用STM32的片內(nèi)Flash存儲中文字庫

            作者: 時間:2016-11-19 來源:網(wǎng)絡(luò) 收藏
            嵌入式系統(tǒng)中,成本往往是敏感的,如果你的Flash足夠大,就可以省去片外Flash,我用結(jié)構(gòu)體實現(xiàn)了該功能,并分享給廣大網(wǎng)友,最后附有下載鏈接。

            在fonts.h中:

            本文引用地址:http://www.biyoush.com/article/201611/318125.htm

            typedef struct _tFont

            const uint16_t *table;
            uint16_t Width;
            uint16_t Height;

            } sFONT;

            在fonts.c中

            const uint16_t ASCII16x24_Table []={………………};//字模

            sFONT Font16x24 = {
            ASCII16x24_Table,
            16,
            24,
            };

            sFONT Font12x12 = {
            ASCII12x12_Table,
            12,
            12,
            };

            sFONT Font8x12 = {
            ASCII8x12_Table,

            8,
            8,
