Wire Connections and Setup
The OLED display on the Basic I/O Shield is driven through SPI interface. This requires the JP4 jumper on chipKIT Uno32 board be placed on the RG9 position so that the SPI SS function is available on Pin 10. Read our tutorial Exploring the chipKIT Uno32 for more details on jumper functions and settings on the Uno32 board. The following picture shows the required jumper settings on Uno32 board for this project.
