<b>NuvoTon NUC120</b>.
|
||||||
|
This is a port of NuttX to the Nuvoton NuTiny-SDK-NUC120 that features the NUC120LE3AN MCU.

|
||||||

<ul>

|
||||||
|
<b>STATUS</b>.
|
||||||
|
As of this writing, this is very much a work in progress.
|
||||||
|
For a full-featured RTOS such as NuttX, providing support in a usable and meaningful way within the tiny memories of the NUC120 will be a challenge (128KB FLASH and 16KB of SRAM).
|
||||||
|
Initial support for the NUC120 is expected in NuttX-6.26.
