NXP LPC176x
|
|
-----------
|
|
|
|
NXP LPC1766, LPC1768, and LPC1769. Drivers are available for CAN, DAC,
|
|
Ethernet, GPIO, GPIO interrupts, I2C, UARTs, SPI, SSP, USB host, and USB
|
|
device. Additional drivers for the RTC, ADC, DAC, Timers, PWM and MCPWM
|
|
were contributed by Max (himax) in NuttX-7.3. Verified LPC17xx
|
|
configurations are available for these boards:
|
|
|
|
- The Nucleus 2G board from `2G Engineering <http://www.2g-eng.com/>`__
|
|
(LPC1768),
|
|
- The mbed board from `mbed.org <http://mbed.org>`__ (LPC1768,
|
|
Contributed by Dave Marples), and
|
|
- The LPC1766-STK board from `Olimex <http://www.olimex.com/>`__
|
|
(LPC1766).
|
|
- The Embedded Artists base board with NXP LPCXpresso LPC1768.
|
|
- Zilogic's ZKIT-ARM-1769 board.
|
|
- The `Micromint <http://micromint.com/>`__ Lincoln60 board with an NXP
|
|
LPC1769.
|
|
- A version of the LPCXPresso LPC1768 board with special support for
|
|
the U-Blox model evaluation board.
|
|
- Support for the Keil MCB1700 was contributed by Alan Carvalho de
|
|
Assis in NuttX-7.23.
|
|
- Support for the NXP Semiconductors' PN5180 NFC Frontend Development
|
|
Kit was contributed by Michael Jung in NuttX-7.1. This board is based
|
|
on the NXP LPC1769 MCU.
|
|
|
|
The Nucleus 2G board, the mbed board, the LPCXpresso, and the MCB1700
|
|
all feature the NXP LPC1768 MCU; the Olimex LPC1766-STK board features
|
|
an LPC1766. All use a GNU arm-nuttx-elf or arm-eabi toolchain\* under
|
|
either Linux or Cygwin (with native Windows GNU tools or Cygwin-based
|
|
GNU tools).
|
|
|
|
**STATUS:** The following summarizes the features that has been
|
|
developed and verified on individual LPC17xx-based boards. These
|
|
features should, however, be common and available for all LPC17xx-based
|
|
boards.
|
|
|
|
#. **Nucleus2G LPC1768**
|
|
|
|
- Some initial files for the LPC17xx family were released in NuttX
|
|
5.6, but
|
|
- The first functional release for the NXP LPC1768/Nucleus2G
|
|
occurred with NuttX 5.7 with Some additional enhancements through
|
|
NuttX-5.9. Refer to the NuttX board
|
|
`README <https://bitbucket.org/patacongo/obsoleted/src/master/configs/nucleus2g/README.txt>`__
|
|
file for further information.
|
|
|
|
That initial, 5.6, basic release included *timer* interrupts and a
|
|
*serial console* and was verified using the NuttX OS test
|
|
(``apps/examples/ostest``). Configurations available include include
|
|
a verified NuttShell (NSH) configuration (see :ref:`NSH <nsh>`). The
|
|
NSH configuration supports the Nucleus2G's microSD slot and
|
|
additional configurations are available to exercise the USB serial
|
|
and USB mass storage devices. However, due to some technical reasons,
|
|
neither the SPI nor the USB device drivers are fully verified.
|
|
(Although they have since been verified on other platforms; this
|
|
needs to be revisited on the Nucleus2G).
|
|
|
|
**Obsoleted**. Support for the Nucleus2G board was terminated on
|
|
2016-04-12. There has not been any activity with the commercial board
|
|
in a few years and it no longer appears to be available from the
|
|
2g-eng.com website. Since the board is commercial and no longer
|
|
publicly available, it no longer qualifies for inclusion in the open
|
|
source repositories. A snapshot of the code is still available in the
|
|
`Obsoleted
|
|
repository <https://bitbucket.org/patacongo/obsoleted/src/master/boards/nucleus2g>`__
|
|
and can easily be *reconstitued* if needed.
|
|
|
|
#. **mbed LPC1768**
|
|
|
|
- Support for the mbed board was contributed by Dave Marples and
|
|
released in NuttX-5.11. Refer to the NuttX board
|
|
`README <https://github.com/apache/nuttx/blob/master/boards/arm/lpc17xx_40xx/mbed/README.txt>`__
|
|
file for further information.
|
|
|
|
#. **Olimex LPC1766-STK**
|
|
|
|
- Support for that Olimex-LPC1766-STK board was added to NuttX 5.13.
|
|
- The NuttX-5.14 release extended that support with an *Ethernet
|
|
driver*.
|
|
- The NuttX-5.15 release further extended the support with a
|
|
functional *USB device driver* and *SPI-based micro-SD*.
|
|
- The NuttX-5.16 release added a functional *USB host controller
|
|
driver* and *USB host mass storage class driver*.
|
|
- The NuttX-5.17 released added support for low-speed USB devices,
|
|
interrupt endpoints, and a *USB host HID keyboard class driver*.
|
|
- Refer to the NuttX board
|
|
`README <https://github.com/apache/nuttx/blob/master/boards/arm/lpc17xx_40xx/olimex-lpc1766stk/README.txt>`__
|
|
file for further information.
|
|
|
|
Verified configurations are now available for the NuttShell with
|
|
networking and microSD support(NSH, see :ref:`NSH <nsh>`), for
|
|
the NuttX network test, for the
|
|
`THTTPD <http://acme.com/software/thttpd>`__ webserver, for USB
|
|
serial deive and USB storage devices examples, and for the USB host
|
|
HID keyboard driver. Support for the USB host mass storage device can
|
|
optionally be configured for the NSH example. A driver for the *Nokia
|
|
6100 LCD* and an NX graphics configuration for the Olimex LPC1766-STK
|
|
have been added. However, neither the LCD driver nor the NX
|
|
configuration have been verified as of the NuttX-5.17 release.
|
|
|
|
#. **Embedded Artists base board with NXP LPCXpresso LPC1768**
|
|
|
|
An fully verified board configuration is included in NuttX-6.2. The
|
|
Code Red toolchain is supported under either Linux or Windows.
|
|
Verified configurations include DHCPD, the NuttShell (NSH), NuttX
|
|
graphis (NX), THTTPD, and USB mass storage device. Refer to the NuttX
|
|
board
|
|
`README <https://github.com/apache/nuttx/blob/master/boards/arm/lpc17xx_40xx/lpcxpresso-lpc1768/README.txt>`__

|
|
|
|
Zilogic System's ARM development Kit, ZKIT-ARM-1769. This board is
|
|
based on the NXP LPC1769. The initial release was included
|
|
NuttX-6.26. The NuttX Buildroot toolchain is used by default. Verifed
|
|
configurations include the "Hello, World!" example application and a
|
|
THTTPD demonstration. Refer to the NuttX board

|
#. **Micromint Lincoln60 board with an NXP LPC1769**
|
|
|
|
This board configuration was contributed and made available in
|
|
NuttX-6.20. As contributed board support, I am unsure of what all has
|
|
been verfied and what has not. See the Microment website
|
|
and the NuttX board

#. **U-Blox Modem Evaluation (LPCXpresso LPC1768)**
|
|
|
|
This board configuration was contributed by Vladimir Komendantskiy
|
|
and made available in NuttX-7.15. This is a variant of the LPCXpresso
|
|
LPC1768 board support with special provisions for the U-Blox Model
|
|
Evaluation board. See the NuttX board

The port of NuttX to the WaveShare Open1788 is a
|
|
collaborative effort between Rommel Marcelo and myself (with Rommel
|
|
being the leading contributor and I claiming only a support role). You
|
|
can get more information at the Open1788 board from the WaveShare
|
