Generally works well, but has some accuracy/overflow problems wide lines

There is a &quot;fudge factor&quot; that seems to eliminate the problem,
but there could still be issues in some configurations.

Refer to the <a href="http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=KWIKSTIK-K40">Freescale web site</a> for further information about this board.
The Kwikstik is used with the FreeScale Tower System (mostly just to provide a simple UART connection)

<b>STATUS:</b>
The unverified KwikStik K40 first appeared in NuttX-6.8
As of this writing, the basic port is complete but I accidentally locked my board during the initial bringup.
Further development is stalled unless I learn how to unlock the device (or until I get another K40).
Additional work remaining includes, among other things: (1) complete the basic bring-up,

As of this writing, the basic port is complete and passes the NuttX OS test.
An additional, validated configuration exists for the NuttShell (NSH, see the
<a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
And Ethernet driver also exists, but has not yet been integrated.
Additional work remaining includes: (1) integrate the Ethernet driver,
(3) develop support for the SDHC-based SD card, and
(4) develop support for USB host and device.
NOTE: Most of these remaining tasks (excluding the Ethernet driver) are the
same as the pending K40 tasks described above.
This basic TWR-K60N512 first appeared in NuttX-6.8.
Ethernet and SD card (SDHC) drivers also exist:
The SDHC driver is partially integrated in to the NSH configuration but has some outstanding issues;
the Ethernet driver is completely untested.
Additional work remaining includes: (1) integrate the Ethernet and SDHC drivers, and (2) develop support for USB host and device.
NOTE: Most of these remaining tasks (excluding the Ethernet driver) are the same as the pending K40 tasks described above.
