We we are far from the start point, but, it is possible to add 2 RPI Zero (cluster) or a RPI3 … Not sure what is the best option.
I have just updated our Github directory with new 3D printable STL files. I keep working.
The next step it to modify the case to accept a RPI Zero and a 3.5 or 2.8 OLED display. Various OLED display direction to have something nice
We are making 3D files for the case. We first start with the lower case to be able to rearrange the possibility to add extra PCBs.
Soon, we will also rearrange the upper case to re-use keyboard and have a proper opening for the new OLED display.
Larry’s SMART Response XE support library
1) LCD initialization (4-gray levels) and support to draw 4 sizes of characters and outline+filled rectangles
2) Functions to erase/write/read the external 128K byte SPI FLASH memory
3) Fast GPIO access with simplified pin numbering (e.g. PORTD bit3 = pin 0xD3)
4) Scan the keyboard and return pressed keys translated with the shift/sym keys
