A recent hardware upgrade resulted in the lack of a real RS-232 port, so I grabbed the first RS-232 to USB converter I could find which happened to be the Aten (iogear) UC-232A which Linux 2.6 supports using the Profilic pl2302 driver.

Bundled with the latest version is a Perl example, collecting values from multiple sensors and submitting the averages to rrdtool using a single RRDs::update() invocation at a configurable interval. It can be invoked like this:
$ ./tl-500 | examples/tl-500-rrd.pl temperature.rrd 300

The program has now been tested with the following sensors:
- TL-3TSN temperature sensor
- TSN-EXT44 temperature sensor with external probe
- TSN-33MN waterproof temperature sensor
- TSN-TH70E temperature/humidity sensor
Fixes include support for sub-zero temperatures and accurate m68knoreply@blogger.com0tag:blogger.com,1999:blog-7173252577790638762.post-21534534933168261222010-03-04T09:49:00.011+02:002011-03-28T17:38:13.968+03:00FriendlyARM Mini2440 + AREXX TL-500 temperature logger on LinuxSome notes on how to connect the AREXX TL-500 temperature logger system to Linux hosts. Example includes instructions for use with the FriendlyARM Mini2440 ARM9 development board.
As AREXX only provides Windows drivers for the TL-500, accessing it from Linux is not quite straightforward. The TL-500 does not use a generic transfer protocol like FTDI, so we are left with a plain and undocumented m68knoreply@blogger.com10tag:blogger.com,1999:blog-7173252577790638762.post-51241725015208649122010-03-02T13:51:00.004+02:002010-03-02T18:17:09.831+02:00FriendlyARM Mini2440 + Huawei E160 HSDPA USB modemBrief description of how to hook up a Huawei E160 HSDPA USB modem to the FriedlyARM Mini2440 ARM9 development board without breaking a sweat.
The Linux kernel preinstalled on the board does not have the ppp driver, so the first order of business is to recompile and replace the kernel. Fetch the prepared kernel source package:
