r_glcd Module Guide Resources

Last Updated:07/31/2017


Where can I find the references to module guide resources for the GLCD HAL module on r_glcd?


Information on the module guide itself and the associated resources and known issues are available here.


The GLCD HAL module is a high-level API for GLCD applications and is implemented on r_GLCD. The GLCD HAL module uses the Graphics LCD Driver peripheral on the Synergy MCU. A user-defined callback can be created to handle frame buffer switching and underflow detection.

The GLCD HAL module supports the following features:

  • Supports LCD panels with RGB interface (up to 24 bits) and sync signals (HSYNC, VSYNC, and Data Enable(optional)
  • Supports various color formats for input graphics planes (RGB888, ARGB888, RGB565, ARGB1555, ARGB4444, CLUT8, CLUT4, CLUT1)
  • Supports CLUT (Color Look-Up Table) usage for input graphics planes with 512 words (32 bits/word)
  • Supports various color formats for output (RGB888, RGB666, RGB565, Serial RGB)
  • Can input two graphics planes on top of the background plane and blend them on the screen
  • Generates a dot clock to the panel. The clock source is selectable from internal or external (LCD_EXTCLK)
  • Supports brightness adjustment, contrast adjustment, and gamma correction
  • Supports GLCDCC interrupts to handle frame buffer switching or underflow detection

Module Guide
