NuttX-5.4
|
||
|
|
---------
|
||
|
|
|
||
|
|
This is the 51st release of NuttX. This release includes one new,
|
||
|
|
important extension to th NX graphics system (See
|
||
|
|
https://nuttx.apache.org/docs/latest/components/nxgraphics/index.html).
|
||
|
|
|
||
|
|
NX was develop a couple years back on hardware that supported only
|
||
|
|
framebuffer devices, that is, video hardware with video memory
|
||
|
|
directly converts the memory content to video. However, most MCUs
|
||
|
|
that NuttX focuses on do not support such video memory; rather,
|
||
|
|
that typically only support LCDs via parallel or serial interfaces.
|
||
|
|
|
||
|
|
This release of NuttX extends NX so that now renders directly to
|
||
|
|
the LCD device via its serial or parallel interface. No in-memory
|
||
|
|
copy of the screen memory need be maintained so this solution should
|
||
|
|
also work in MCUs with very limited SRAM.
|
||
|
|
|
||
|
|
This initial release of this feature includes the verified NX
|
||
|
|
extensions plus a driver for the HX8347, 16-bit parallel LCD. This
|
||
|
|
LCD supports 16-bit RGB (5:6:5).
