PanelOne on Sanguinololu

The PanelOne LCD display and control panel was originally designed for RAMPS1.4, and that is still the most sensible way to use it as it uses two 2x5 IDC cables that are readily available. The PanelOne circuit board is designed to work with 3.3V and 5V electronics and this weekend I tested it with Sanguinololu (effectively going full circle back to the original Panelolu - just a lot easier to put together and use!)

This works fine, although you do need to be careful to plug the pins in correctly:

The correct pins for Sanguinololu are:

Wire number    PanelOne             Sanguinololu
                         Aux2
1                       5V                         5V
2                       GND                     GND
3                       EN B                     Rx1
4                       EN A                     Tx1
5                       LCD DB7              A4
6                       LCD RS                PWM
7                       LCD DB6              A3
8                       LCD E                  SDA
9                       LCD DB5              A2
10                     LCD DB4              A1
                         Aux3
1 Not Connected
2 Not Connected
3                       CS                        A0
4                       CLK                      SCK
5                       DO                        MOSI
6                       DI                          MISO
7                       EN SW                  SCL
8                       VCC                      5V
9 Not Connected
10 Not Connected

This blog post has a good image of the location of each pin on the Sanguinololu, re-posted below:

The IDC cables are numbered with wire 1 being the red coloured wire.

This will work out the box with the T3P3 version of Marlin by enabling #SDSUPPORT and #ULTIMAKERCONTROLLER in configuration.h

The process followed can be adapted to use the PanelOne on any electronics that runs Marlin and has enough free pins. Do let me know if you get it working on another board!
