Detailed Description

Remarks

about the improved bitmap rendering

The function ucg_BitmapPrint prints the bitmap pixel by pixel The ucg_DrawBmpLine, ucg_DrawBmp, ucg_DrawBmpRotate and the new function ucg_BitmapPrint prints the bitmap line by line. The idea of the improved bitmap rendering is borrowed from: https://p3dt.net/post/2018/12/27/esp8266-ili9846-improved.html The new functions should actually be added to devices files ucg_dev_ic_XXXX.c. In this case the functions for ST7735 are added to ucg_bmp.c. These functions need four constants, which are declared in ucg_dev_ic_st7735.c.
