Itead Joystick configuration settings:
System Type -> SAMA5 Peripheral Support
CONFIG_SAMA5_ADC=y : Enable ADC driver support
CONFIG_SAMA5_TC0=y : Enable the Timer/counter library need for periodic sampling
CONFIG_SAMA5_EMACA=n : 10/100Mbit Ethernet MAC conflicts
CONFIG_SAMA5_SSC0=n : SSC0 Audio conflicts
CONFIG_SAMA5_SPI1=? : SPI1 might conflict if PCS3 is used
CONFIG_SAMA5_ISI=? : ISIS conflics if bit 9 is used
System Type -> PIO Interrupts
CONFIG_SAMA5_PIO_IRQ=y : PIO interrupt support is required
CONFIG_SAMA5_PIOC_IRQ=y : PIOC interrupt support is required
Drivers
CONFIG_ANALOG=y : Should be automatically selected
CONFIG_ADC=y : Should be automatically selected
CONFIG_INPUT=y : Select input device support
CONFIG_AJOYSTICK=y : Select analog joystick support
System Type -> ADC Configuration
CONFIG_SAMA5_ADC_CHAN0=y : These settings enable the sequencer to collect
CONFIG_SAMA5_ADC_CHAN1=y : Samples from ADC channels 0-1 on each trigger
CONFIG_SAMA5_ADC_SEQUENCER=y
CONFIG_SAMA5_ADC_TIOA0TRIG=y : Trigger on the TC0, channel 0 output A
CONFIG_SAMA5_ADC_TIOAFREQ=10 : At a frequency of 10Hz
CONFIG_SAMA5_ADC_TIOA_RISING=y : Trigger on the rising edge
Default ADC settings (like gain and offset) may also be set if desired.
System Type -> Timer/counter Configuration
CONFIG_SAMA5_TC0_TIOA0=y : Should be automatically selected
Library routines
CONFIG_SCHED_WORKQUEUE=y : Work queue support is needed
This enables the analog joystick example at apps/examples/ajoystick:
CONFIG_EXAMPLES_AJOYSTICK=y
CONFIG_EXAMPLES_AJOYSTICK_DEVNAME="/dev/ajoy0"
CONFIG_EXAMPLES_AJOYSTICK_SIGNO=13
