| 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). |
