FT813 (or BT815) few fonts at the same time.

FTDI Community:
Hi,

Yes here is an example of SetFont2 below.

Also, as Rudolph mentioned, the BT81x can use font .glyph flies directly from FLASH. But the .xfont file should be copied to RAM_G. This can either be stored on the MCU or can be stored on flash and then copied by your code to RAM_G.


--- Code: ---void SAMAPP_ExtendedFormat_Font()
{
SAMAPP_API_Screen("Unicode Font");
#define UNICODE_HANDLE 30
Gpu_FontsExt_t font;
uint32_t fontAddr = RAM_G;
//Load glyph file into BT815's flash
//Load xfont file into graphics RAM

/* Switch Flash to FULL Mode */
Gpu_CoCmd_FlashHelper_SwitchFullMode(g_phost);
Gpu_Hal_LoadImageToMemory(g_phost, TEST_DIR "\\mssong_20.xfont", fontAddr, LOAD);
Gpu_Hal_WaitCmdfifo_empty(g_phost);

Gpu_CoCmd_Dlstart(g_phost);
App_WrCoCmd_Buffer(g_phost, CLEAR(1, 1, 1));
App_WrCoCmd_Buffer(g_phost, COLOR_RGB(255, 255, 255));

Gpu_CoCmd_SetFont2(g_phost, UNICODE_HANDLE, fontAddr, 0);
Gpu_CoCmd_Text(g_phost, 0, 0, UNICODE_HANDLE, 0, u8"BRT的EVE技术是一个革命性的概念，");
Gpu_CoCmd_Text(g_phost, 0, 30, UNICODE_HANDLE, 0, u8"利用面向对象的方法创建高质量的人机界面（HMI） 同时支持显示，");
Gpu_CoCmd_Text(g_phost, 0, 60, UNICODE_HANDLE, 0, u8"音频和触摸功能。");
App_WrCoCmd_Buffer(g_phost, DISPLAY());
Gpu_CoCmd_Swap(g_phost);
App_Flush_Co_Buffer(g_phost);
Gpu_Hal_WaitCmdfifo_empty(g_phost);
Gpu_Hal_Sleep(4000);
}
--- End code ---
