misoA SPI(miso) pin, for the spi interface of the mouse chip (SDIO)
sclkA SPI(sclk) pin, for the spi interface of the mouse chip (SCLK)
ncsA DigitalOut, set low for chip select
resetA DigitalOut, set high for chip reset
npdA DigitalOut, set high for chip powerdown

Definition at line 3 of file ADNS6010.cpp.

Member Function Documentation

void changeCPI ( int  cpi )
