 set the PWM frequency of a PWM-enabled pin. Note that on SAMD09, SAMD11 boards the frequency will be mapped to closest match fixed frequencies. Also note that PWM pins 4 and 5 share a timer, and PWM pins 6 and 7 share a timer. Changing the frequency for one pin will change the frequency for the other pin that is on the timer. More...
 
void enableSercomDataRdyInterrupt (uint8_t sercom=0)
 Enable the data ready interrupt on the passed sercom. Note that both the interrupt module and the passed sercom must be compiled into the seesaw firmware for this to function.

On the default seesaw firmeare on the SAMD09 breakout, no sercoms are enabled. More...

 Disable the data ready interrupt on the passed sercom. More...

 enable the keypad interrupt that fires when events are in the fifo.
 
void disableKeypadInterrupt ()
 disable the keypad interrupt that fires when events are in the fifo.
 
uint8_t getKeypadCount ()
 Get the number of events currently in the fifo. More...
 
bool readKeypad (keyEventRaw *buf, uint8_t count)
 Read all keyEvents into the passed buffer. More...
 
float getTemp ()
 Read the temperature of the seesaw board in degrees Celsius. NOTE: not all seesaw firmwares have the temperature sensor enabled. More...

 Set the current position of the encoder. More...
 
virtual size_t write (uint8_t)
 The print wrapper for the seesaw class. Calling this allows you to use ss.print() or ss.println() and write to the UART on SERCOM0 of the seesaw. 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. 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...
