This library supports one display per instance of the gspSeven class.
Cascading devices on the MAX2719 driver DOES_NOT_WORK consistently with the software SPI driver.
Consequently a different wiring strategy needs to be used. Fortunately this does not require a massive number of additional pins.
All displays can share pins for:
- VCC
- GND
- CLK
- DataIn
Each display needs its own:
- CS/LOAD pin
Don't try and write to multiple displays at the same time, so only activate one CS/LOAD Pin at any one time.
