add a reset button for the raspberry pi to the layout

Modify the dotstar.so to use spi0.1 with chip select according to #3.

Optionally add a level shifter according to the Adafruit Dotstar Painter to the shield.
Connect the !OE pins to !CE1 instead to GND.

add labels for GND, CLK and DATA for X6

add connector for at least three input switches:

• push button to start production
• switch for juice door
• switch for control door

add input for a start button IUNO-TDM/MixerFrame#3
add output with open collector for driving the illumination of a button up to 24V

Add author notices and logos to silkscreen:

• Jan Rauser
• Hans-Peter Bock
• TRUMPF Werkzeugmaschinen GmbH + Co. KG
• Open Hardware
• Creative Commons

It seems to be impossible to drive dotstar LEDs using spidev1.1 on raspberry pi. Maybe because dma seems not to be supported by raspberry pi on spi1. All changes shall be rolled back to use spidev0.1:

• Motorshield layout and wiring
• Adafruit DotStar Pi library in IUNO organisation
• Pumpcontrol

Establish compatibility with the s.usv Pi hat that uses some GPIOs that the MotorShield uses.

pins used by s.usv

• Move input for start button to be near X5.
• Add wire labels for X4 to silk screen.

move the screw holes for the spacers so that they fit the raspberry pi 3 layout

Add inputs for buttons that detect wether a door is opened or closed.

add labels that mark + and - to X5

add LEDs that indicate if an output is on

change pads of L1 so it is easily possible to solder L1 by hand

With a real shortcut at the motor connector, the mosfet trips quicker (always on) than the polyfuse.

Die Breite der Pins der AKL-Buchsen sind Reckteckig und haben die Maße 0,8x0,8 mm.
Vias sind kreisförmig und haben einen Durchmesser von 0,9mm.

--> Größe der Vias müssen auf einen Mindestdurchmesser von 1,6mm vergrößert werden.

The shield shall signal if a fuse has tripped. This could be signaled e.g. by a red LED.

Die Anschlüsse MISO und MOSI für die SPI-Verbindung zwischen dem ADC (MCP3008) und dem Raspberry Pi sind vertauscht.
Der output Pin Din des ADC ist mit MISO verbunden.
Der input Pin Dout mit MOSI.

--> Din mit MOSI verbinden.
-->Dout mit MISO verbinden.

Change the power input to a barrel connector to which a power supply unit like MW 2108GS/F2USB can easily be connected. Consider that the barrel connector is suitable for the expected maximum current.

add 22nF condensator to debounce the push button inputs

the AKL connectors are designed out of grid and can not be connected to a net. The connectors could be changed to use PxC MSTB connectors. These footprints are already contained in the eagle libraries.

Place big and visible labels for DCIN and GND at the power input connector.

The Wago 233-202 is not available at the distributor.

All WAGO clamps shall be exchanged from 233-20x to 233-50x since these are available and fit better to the pcbs grid.
