|
||||
This release includes one several new drivers for existing NuttX ports:
|
||||
This release adds basic support for one new ARM Cortex-M3 architecture:
|
||||
<ul>
|
||||
<li>
|
||||
This port adds support for the RiT displays P14201 4-bpp, greyscale OLED.
|
||||
4-bpp greyscale support was integrated into the NX graphics sub-system and
|
||||
verified using the TI/Luminary LP3S6965 Ethernet Evaluation Kit.
|
||||
Added support for NXP LPC1768 MCU as provided on the Nucleus 2G board from
|
||||
<a href="http://www.2g-eng.com">2G Engineering</a>.
|
||||
</li>
|
||||
<li>
|
||||
The MP25Px driver was extended for the M24P1 FLASH part (see NOTE).
|
||||
Some initial files for the LPC17xx family were released in NuttX 5.6, but the
|
||||
first functional release for the NXP LPC1768/Nucleus2G occured with NuttX 5.7.
|
||||
</li>
|
||||
<li>
|
||||
An I2C driver and (basic) SPI driver were added for the NXP LPC313x port.
|
||||
The I2C interface definition was extended to efficiently handle multiple I2C
|
||||
transfers (See NOTE).
|
||||
That initial basic release included timer interrupts and a serial console and was
|
||||
verified using the NuttX OS test.
|
||||
</li>
|
||||
<li>
|
||||
That release includes a verified NuttShell (NSH) configuration
|
||||
(see the <a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
|
||||
Also included are unverified SPI and USB device drivers.
|
||||
</li>
|
||||
</ul>
|
||||
</p>
|
||||
<p>
|
||||
As well as a few, important USB-related bugfixes (See the ChangeLog for details).
|
||||
</p>
|
||||
<p>
|
||||
This release also includes the beginnings of a port for the NXP LPC1768 MCU. However,
|
||||
it is too early for that port to be useful (stay tuned for a future announcement of the
|
||||
availability of the verified LPC1768 port).
|
||||
</p>
|
||||
<p>
|
||||
<small><b>NOTE</b>: Contributed by David Hewson where noted.</small>
|
||||
Further efforts include: (1) development of a DMA support library, (2) SPI-based MMC/SD
|
||||
support, and (3) verification of the USB driver. Watch for announcement of the completed
|
||||
LPC1768 port expected in NuttX-5.8.

<b>NXP LPC1768</b>.
|
||||
This port uses the Nucleus 2G board from <a href="http://www.2g-eng.com/">2G Engineering</a>
|
||||
featuring the NXP LPC1768 MCU.
|
||||
This port uses a GNU arm-elf or arm-eabi toolchain* under either Linux or Cygwin (with native Windows GNU
|

tools or Cygwin-based GNU tools).

<b>STATUS:</b>
|
||||
Some initial files for the LPCP17xx family were released in NuttX 5.6, but that port is not yet ready for general use
|
||||
(I, in fact, still do not have hardware in hand).
|
||||
Look for the announcement of the LPC1768 NuttX port in a future release.
|
||||
Some initial files for the LPC17xx family were released in NuttX 5.6, but the first
|
||||
functional release for the NXP LPC1768/Nucleus2G occured with NuttX 5.7.
|
||||
That initial basic release included timer interrupts and a serial console and was
|
||||
verified using the NuttX OS test (<code>examples/ostest</code>).
|
||||
That release includes a verified NuttShell (NSH) configuration
|
||||
(see the <a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
|
||||
Also included are unverified SPI and USB device drivers.
|
||||
</p>
|
||||
<p>
|
||||
Current efforts include: (1) development of a DMA support library, (2) SPI-based MMC/SD
|

support, and (3) verification of the USB driver.

Watch for announcement of the completed LPC1768 port expected in NuttX-5.8.

|
||||
<b>Development Environments:</b>
|
||||
Same as for the other Cortex-M3 ports.
|
||||
1) Linux with native Linux GNU toolchain, 2) Cygwin with Cygwin GNU toolchain, or 3) Cygwin
|
||||
with Windows native toolchain (CodeSourcery or devkitARM). A DIY toolchain for Linux
|
||||
or Cygwin is provided by the NuttX
