Unit TFT Framebuffer
Return to Unit Reference
Description
This is a generic framebuffer device support unit for SPI based TFT screens using common chipsets.
This unit implements the shared functionality that is common to all devices and provides a set of functions that device specific drivers must implement. For each supported device a driver unit is required that implements the SPI communications to initialize the device, setup resolution and color depth as well as refreshing the framebuffer data to the device memory on change.
The resulting device created by the combination of this unit and a device specific driver is registered with Ultibo as a framebuffer device that can be accessed using all of the standard framebuffer API functions.
For examples of drivers that use this support unit see the HX8357D and ILI9340 units.
