Hello,
I'm trying to show received data on an external Display (EADOG-162). The communication between the NRG3 and the display is over SPI. When I try to initalise SPI with "SPI.begin" I get an error "undefined reference to `SPI'". The Header File of the SPIclass is there ("C:\Users\jan-c\Documents\ArduinoData\packages\panstamp_nrg\hardware\msp430\1.1.0\libraries\SPI"). Any suggestions to solve the problem?
This is my test code
Thanks in advance![Smile]( "Smile")
