Note that this functionality is only available when the UART (sercom) module is compiled into the seesaw firmware. On the default seesaw firmware on the SAMD09 breakout this functionality is not available. More... | |
| virtual size_t | write (const char *str) |
| The print wrapper for the seesaw class allowing the user to print a string. Calling this allows you to use ss.print() or ss.println() and write to the UART on SERCOM0 of the seesaw.
