Aria Display Manager

MPLAB Harmony Graphics Suite display manager for the aria graphics library is used to tune the display timing interface between the controller and the display. The use of the display manager allows the user to visually inspect the timing and save setting for subsequent code generation. 

 

The following figure illustrates the Display Manager screen. Descriptions for each numbered area follow the figure.

  1. Display Settings – The Display Settings panel controls the size and orientation of the display. Under the Configuration Options of the GFX Core component is parallel set of display settings.

  1. Active Area / Hidden Area Diagram – This mimics the display active area transposed over the hidden area as often shown in display data sheets. It also provides a simulation of how the display behaves on the hardware. Note that in Harmony 3 horizontal and vertical syncs are not shown.
  2. Signal Timing – This panel supports the display timing of the display. These timing values are also shown on the Active Area / Hidden Area Diagram.

These settings are also available in GFX Core Configuration Options:

Here is a map between the Display Settings and the Active Area diagram in Display Manager:

  1. Driver Settings –This Display Manager panel controls how the graphics driver is setup. There is an equivalent set of controls under GFX Core's Configuration Options > Driver Configuration Hints.

The pixel clock for the E70 LCC driver is fixed at about 45 MHz. This is because the master clock that feeds the DMA is shared with the other peripherals. Since the setup is fixed it not shown in the Driver Settings panel.

  1. H-SYNC Waveforms / V-SYNC Waveforms – This panel provides timing diagrams for the horizontal and vertical sync signals. Here is a repeat of the figure shown in 3 above with the back porches set to 5 to distinguish between front and back porches:

The corresponding Horizontal Sync waveforms are:

The corresponding Vertical Sync waveforms are:
