Functions |
|
| EMSTATUS | GLIB_applyClippingRegion (const GLIB_Context_t *pContext) |
|
Apply the clipping region from the GLIB_Context_t in the DMD driver.
|
|
| EMSTATUS | GLIB_clear ( GLIB_Context_t *pContext) |
|
Clears the display with the background color of the GLIB_Context_t.
|
|
| EMSTATUS | GLIB_clearRegion (const GLIB_Context_t *pContext) |
|
Clears the clipping region by filling it with the background color of the GLIB_Context_t.
|
|
| void | GLIB_colorTranslate24bpp (uint32_t color, uint8_t *red, uint8_t *green, uint8_t *blue) |
|
Extracts the color components from the 32-bit color passed and puts them in the passed in 8-bits ints. The color is 24-bit RGB.
|
|
| EMSTATUS | GLIB_contextInit ( GLIB_Context_t *pContext) |
|
Initialize the GLIB_Context_t.
|
|
| EMSTATUS | GLIB_displaySleep () |
|
Sets the display in sleep mode.
|
|
| EMSTATUS | GLIB_displayWakeUp () |
|
Returns the display from sleep mode.
|
|
| EMSTATUS | GLIB_drawPixel ( GLIB_Context_t *pContext, int32_t x, int32_t y) |
|
Draws a pixel at x, y using foregroundColor defined in the GLIB_Context_t.
|
|
| EMSTATUS | GLIB_drawPixelColor ( GLIB_Context_t *pContext, int32_t x, int32_t y, uint32_t color) |
|
Draws a pixel at x, y using the color parameter.
|
|
| EMSTATUS | GLIB_drawPixelRGB ( GLIB_Context_t *pContext, int32_t x, int32_t y, uint8_t red, uint8_t green, uint8_t blue) |
|
Draws a pixel at x, y with color defined by red, green and blue 1 byte per channel.
|
|
| EMSTATUS | GLIB_resetClippingRegion ( GLIB_Context_t *pContext) |
|
Reset the GLIB_Context_t clipping region to the whole display.
|
|
| EMSTATUS | GLIB_resetDisplayClippingArea ( GLIB_Context_t *pContext) |
|
Reset the display driver clipping area to the whole display.
|
|
| uint32_t | GLIB_rgbColor (uint8_t red, uint8_t green, uint8_t blue) |
|
Convert 3 uint8_t color components into a 24-bit color.
|
|
| EMSTATUS | GLIB_setClippingRegion ( GLIB_Context_t *pContext, const GLIB_Rectangle_t *pRect) |
|
Sets the clippingRegion of the passed in GLIB_Context_t.

Macro Definition Documentation
| #define GLIB_DEFAULT_FONT (( GLIB_Font_t *)& GLIB_FontNormal8x8 ) |
Define the default font. An application can override the default font by defining GLIB_NO_DEFAULT_FONT and by providing a custom GLIB_DEFAULT_FONT macro that points to a GLIB_Font_t structure that should be used as a default font.
