bt81x-spin's Issues

FTBFS using FlexSpin

Fails to build because of missing symbols from the display model/resolution/size-specific files included in the top object. This trick works with OpenSpin because #defines are recognized globally throughout the project, but this isn't the case with FlexSpin - they're only visible to the file they are defined in.

The way timings are specified will have to be structured differently. More memory usage, but a child object containing a DAT block with a structure may be easiest?

Add demo for storing TS cal in EE

Currently when touchscreen calibration is performed (resistive models), the results aren't stored anywhere, so it must be done every time the app is started. Add some code to optionally store it in EE (or flash in the case of P2).

Add support for flash chips

EVE3 can read/write SPI flash chips, commonly used to store things like fonts, audio files, etc.

  • low-level flash i/o support
  • support for displaying bitmaps from flash

Add presets for various available display modules

There should be some preset_() methods in the driver to set it up for some of the display modules available from, e.g., Matrix Orbital, Newhaven. This might be a little more intuitive than having separate files #included by the top-level application.

  • Matrix Orbital 3.5" capacitive-touch
  • Matrix Orbital 3.5" resistive-touch
  • Matrix Orbital 4.3" resistive-touch
  • Matrix Orbital 5.0" capacitive-touch
  • Matrix Orbital 7.0" capacitive-touch

spin1 inter-demo delays inconsistent

Delay units should always be milliseconds; some of the inter-demo delays were inadvertently left at seconds, so the wait time gives the appearance the demo is hung.
