  • I am a little confused with your SERCOM chart and the available ports. If I understand it correctly, does this mean that I can have more than one i2C or more than 1 SPI for example? Also I am not clear on the “DEV ONLY” category - could you please clarify that and lastly you mentioned “ That leaves SERCOM1 and SERCOM3 that you can bend to your will ..” should that be SERCOM1 and SERCOM2 since SERCOM3 is already I2C.


  • Excellent guide! Thank you

  • I am unable to access the link provided on the Sharp Site for the SD SPI protocol. Could someone please post the correct link or post the document on the SF site.

No public wish lists :(
