 In Germany it is allowed to use electronic parking discs if it has an E24 number. \\
-As the plastic casing has melted in summer (they use thermoplastics, d'oh!), I did not even have to open it, it literally opened itself. I assumed there would be an ASIC inside, but be astonished and read on! \\

 It is really ignorant to use thermoplastics for the case which sits right behind the windshield frizzling in the sun. The four magnets are there to hold a blue plastic plate which is stuck to the windshield - you cannot see it in the pictures as it is still inside the car. \\

-=== MSP430 Pinout ===
+===== Next Steps =====
-The GPIO-Pins of MSP430 are the following: \\
-<insert table>\\
-LCD front and back pinout \\
-#TODO. Pinout part is still missing. \\
-===== Lauchpad programmer =====
-We want to connect a debugger to connect to the pin header of MSP430. I used a Lauchpad programmer dev-board collecting dust. \\

-==== Output ====
-When connecting, we get the following initial output: \\
-<hidden Show ouput>
-<code>

-==== Dumping ====
-The lock bits are set to:\\

-Glitching?\\
+Due to lack of time, I had to stop here. Next steps could be: \\

-==== Accelerometer ====
+- Connect Lauchpad programmer to header \\
-The Accelerometer comes in IC package -16. \\
+- Dumping Firmware: check lock-bits -> Glitching? -> Dump! \\
+- send I2C "WHO_AM_I" request to accelerometer (LGA-16 package IC) \\
