I would like to expand the IO capability of the Arduino using SPI (preferably) or I2C communication and further access the variable holding the IO status in VB.Net ... Can anyone pls guide if this is possible to do. I am not sure if Lattepanda has SPI capability. Moreover all info I get online are how to access the digital & analog IO pins. Can variables be accessed in any way.
