Loxone Einbindung der Termine der Stadtreinigung Hamburg

A quick Loxone Tip for People in Hamburg, Germany. That’s why it is in German…

 

Etwas ganz spezielles für die Hamburger Loxone Miniserver Nutzer: ein PicoC Programm, welches es erlaubt mit seiner Anschrift (Straße und Hausnummer) von der Stadtreinigung Hamburg die Termine der nächsten Abholungen einzubinden. Hamburg hat teilweise recht variable Termine und die sind auch nur ein paar Monate im Voraus als Kalender zu importieren. Mit dem Programm kann man folgendes erhalten:

In wieviel Tagen wird das nächste Mal folgendes abgeholt:
– Restmüll
– Papier
– Wertstoffe
– Bio
– Laub (nur im Herbst)
– Weihnachtsbäume (ja, haben wir wirklich – Termine gibt es nur im Januar)

Zudem gibt es Tage mit mehreren Abholungen (Restmüll und Papier oder Restmüll und Wertstoffe). Deswegen erzeugt das Programm auch einen handlichen Statustext für welche Tonnen und an welchem Tag (nächster Termin) bzw. einen Text wie “In 7 Tagen: Restmüll, Papier”.

Der Sourcecode ist einfach ins Programm Bauteil zu kopieren und STRASSE, sowie HAUSNUMMER durch die korrekte Angabe zu ersetzen.

Charge Master 2016 Serial Protocol

Charge Master 2016 Serial Protocol

The Voltcraft (Conrad) Charge Master 2016 has a completely different protocol from the CM2010 and other devices.

The USB port is still a serial port which is /dev/cu.SLAB_USBtoUART on my Mac. Every second the device sends a package with 19200 baud 8N1. I’ve written a simple python script to demonstrate reading and interpreting the data. For actual use you should add some error handling.

Only one byte in the slot header is unknown (it seems the Windows software is also not using it) and the device header has a few semi-unknown ones (the version, the temperature, etc) – only the chemical setting is actually used by the Window software.

The full source code can be found on GitHub https://github.com/sarnau/cm2016.

ELV Mobile Alerts

Mobile Alerts

This document tries to describe every detail of the Mobile Alerts sensors, which are sold by ELV in Germany, but are also available at the common suspects (Amazon, etc). Be careful buying at Amazon: certain sensors mention Mobile Alerts, but seem to be designed for the US. They are not compatible with the ELV Mobile Alerts ones!

Mobile Alerts is covering mostly climate sensors, but also contains moisture and door/window sensors plus a sound detector, which acts as a gateway for smoke sensors.

The Mobile Alerts are a version of the LaCrosse Alerts Mobile system made for the European market.

Detailed Infomation

Unit Calculator in Objective C

An piece of code I wrote in 2006, which allows you to do mathematical calculations with units from Objective-C. I’ve updated the code to Objective-C with properties and generics. It is not depended on macOS and should work fine on iOS as well.

By default the result will be in SI compatible units, but all units and prefixes (like kg or ms) can be freely defined in a configuration file units.dat. You can also force a specific unit and add variables to the term. It is also trivial to add new functions, even functions which accept a list of values.

A few examples:

((123.45e-1 + sqrt(+4) -4-.69/2)*2^1/5)^2 => 16
 avg(1,2,3,4) => 2.5
 (9*m^2)^0.5 => 3 m
 60 m + 2 mm => 60.002 m
 sqrt(9 m^2) => 3 m
 20 lb requestedUnit: kg => 9.07185 kg
 60 km/h + 12 m/s requestedUnit: km/h => 103.2 km/h
 1 Torr*760 requestedUnit: atm => 1 atm
 68 F requestedUnit: C => 20 C
 0 C + 0 C requestedUnit: C => 273.15 C --- internally temperatures are converted to Kelvin

The project is an Xcode project with a simple NSLog in the app delegate for testing. It also has a bunch of unit tests to make sure the math works out in all cases.

The code can be found on GitHub.

Label Placement

Implementation of a little algorithm to draw labels/rectangles on a background while trying to avoid overlapping. This is useful for maps, drawing labels on graphs, etc. The sources are – as always – available on GitHub.

In the screenshots you can see the planned area in light grey, while the repositioned ones are in black. The size of the rectangles is arbitrary.

The implementation is specifically simple and not optimized for performance at all. The goal is to be able to understand it.

Raspbian Jessie with a Pi-Raq LCD

The Pi-Raq came with an old version of Raspbian. An upgrade to e.g. Jessie will render the display non-functioning. The manufacturer sadly never got back to me, so I fixed it myself.

Download the archive with all needed files from GitHub.

There are two main things to do:

  1. Provide a custom dt-blob.bin for the pin configuration. This has changed with later version of Raspbian and is the reason why the old file no longer works.
  2. Update a stock config.txt to switch to the LCD.

How to modify the dt-blob.dts

There is very few documenation for this, which is expected, considering that hooking up a custom LCD to a Raspberry is not a very common thing to do.

I used the stock dt-blob.dts as a new base. First I stripped it down, because the Pi-Raq ships with a “Pi 2 Model B rev 1.1” only, which means all other pin configurations are not used anyway and I can’t test it. If you try to use it with a different Raspberry Pi (which seems possible), you have to change the pins_2b2 to match your Raspberry Pi. Use the stock version as an example and transfer the changes over.

By looking at the “Pi-RAQ Hardware Schematic.pdf” you can find out all custom pin mappings:

  • Pin 0 => PCLK-Out (pixel clock)
  • Pin 1 => DE-Out (display enable)
  • Pin 4–8 => B3-B7-Out (5 bits for blue)
  • Pin 9–14 => G2-G7-Out (6 bits for blue, our eyes are more sensitive to green)
  • Pin 15–19 => R3-R7-Out (5 bits for blue)
  • Pin 20–26 are for the jog shuttle controls. They don’t need a custom config, because they are already covered by the pin@default case.
    • Pin 20 = Right button
    • Pin 21 = Left button
    • Pin 22 = Rot1
    • Pin 23 = Center button
    • Pin 24 = Rot2
    • Pin 25 = Down button
    • Pin 26 = Left button
  • Pin 27 is the output for the backlight of the LCD. It has to be an output and should have a startup_state of “active”, otherwise the display stays off after boot. It can still be turned off at any time via a script.

Normal buttons are detected on a falling edge with 100ms debounce. Rotation is doing an edge-detection (both, 10ms debounce). If Rot1 changes and the Rot1 and Rot2 bits are the same, the wheel was rotated left. If both bits have a different value, it was rotated right.

Everything beyond pin 28 is not modified.

How to modify the config.txt

The config.txt has to be modified to switch from HDMI to the LCD. Besides basic changes, like turning overscan off (the LCD doesn’t have a overscan area) and set the framebuffer size to 1024×100 pixel, it is also necessary to enable dpi support (via enable_dpi_lcd), switch the default over and reconfigure the timing and output format for the dpi. Check the comments for a bit more details. The timings and the output format are specific to the LCD panel, which is connected.

Installation Step-by-Step

  1. Install Raspbian on an SD Card
  2. Use ApplePi-Baker to install Raspbian Jessie Lite (the normal version is not needed for this tiny display)
  3. Boot Raspberry with this card. You need to have a HDMI display connected and a USB keyboard
  4. sudo raspi-config => fix the keyboard layout, set a password, changed the hostname, reboot
  5. Remove the card and copy the content of this folder into /home/pi
  6. Put the card back into the Raspberry and boot the Pi-Raq again.
  7. It is typically faster to SSH into the Pi-Raq to configure it, but not necessary.
  8. Now finish the installation:

sudo nano /boot/config.txt

Uncomment/Modify the following lines, which should already be in the config.txt

disable_overscan=1

framebuffer_width=1024
framebuffer_height=100

and add this to the bottom of the file:

The pin configuration of the device tree can be compiled from source:

sudo dtc -I dts -O dtb -o /boot/dt-blob.bin dt-blob.dts

As an alternative to you copy the dt-blob.bin

sudo cp dt-blob.bin /boot/dt-blob.bin

The Raspberry icons occupy a large amount of the vertical space during boot. They can be disabled by adding an option to the cmdline.txt:

sudo nano /boot/cmdline.txt

Add logo.nologo to the parameters. It should look like this after it:

dwc_otg.lpm_enable=0 logo.nologo console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

We should also upgrade and update our installation:

sudo apt-get upgrade && sudo apt-get update

Now we can reboot:

sudo reboot

The HDMI should now be off (and can it be disconnected) and the LCD is used

Launching the demos

To get the demos to work, we need to install a few more python specific pieces:

For AlarmTest we need pygame:

sudo apt-get install python-pygame

This demo can be launched by cd AlarmTest and then python main.py

We need pip to install more Python packages

sudo apt-get install build-essential python-dev python-pip

This is only used for rotTest:

sudo pip install psutil

This demo can be launched by cd rotTest and then python main.py. The demo can be quit via Control-C, but the display stays blank. I haven’t fixed this. sudo reboot solves it…

Mobile Alerts Sensors

ELV is selling affordable weather sensors http://www.elv.de/ip-wettersensoren-system.html, which can be monitored via an iOS application. To allow that all data is transmitted via a gateway to a server, which the application can access. Sadly the protocol is not documented. I don’t think anybody has documented the way the URL has been constructed, especially the MD5 hash over the first part of it.

This sample code integrates sensors into fhem and I wrote it for Mac OS X, but it should work on Linux, too.

All information (and more) is available on GitHub as well.

To integrate the sensors into fhem, add the sensors to the iOS application and check if they show up. You need to note all sensor IDs. The ID is 6 bytes long and represented as a hexadecimal number. This same code supports sensors of type 2 (temperature only) and type 3 (temperature and humidity), which can be recognized via the first two characters of the ID.

You have to adjust the following things in the code:

  • sensors = … Here you have to add all sensors IDs as strings
  • downloadPath This needs to be adjusted to point to the log folder of fhem.
  • vendorid You might want to change the UUID to a new one (just run uuidgen from the terminal)

Atari ST Book: Internal Registers

By looking at the ROM code, available software and the hardware layout I can now document most specialty registers in the ST Book from Atari. I hope it is useful to you. Also available at GitHub.

The main ROM for the ST Book starts at $e0000 and ends at $e3ffff (256kb large). At $e40000 starts the ROM-Disk (also 256kb large), which is automatically activated as drive P.
