EveApps-BT82X is a collection of applications designed as reference resources for Bridgetek's 5th-generation graphics controller, the BT82X.
The collection is divided into two categories: Sample and Demo applications. Both are written in ANSI C, with complete source code provided.
- Sample applications focus on instructional use, demonstrating individual display lists or commands.
- Demo applications are more complex, closely resembling real-world projects. (To be updated)
All applications rely on shared resources located in the "common" folder.
Each application includes a "project" subfolder containing the necessary files for building the application using the MS Visual Studio 2019.
Users are expected to have familiarity with the BT82X programming guide and datasheet.

Note:
- For Eve registers and commands/instructions definition, user can find it at the file common/eve_hal/EVE_GpuDef.h and common/eve_hal/Eve_CoCmd.h.
- For flash blob file used to access the eve connected flash chip, user can find it at common/eve_flash.
Unless specified otherwise, the default hardware platform is the VM820C. You may refer to the details at www.brtchip.com

# EVE_APPS_PLATFORM can be one of : EVE_PLATFORM_FT4222 or EVE_PLATFORM_MPSSE
# [EVE graphics] must be : EVE_GRAPHICS_BT820
# [EVE display] must be: EVE_DISPLAY_WUXGA (1920x1200 LCD)
# [EVE SPI] can be one of : EVE_SPI_QUAD, EVE_SPI_DUAL, EVE_SPI_SINGLE (FT4222 can support Quad/Dual/Single, MPSSE supports single only)
