Joystick:: pJoyParam API properties

JoyHal.c exports the following public structure variable:

JOY_HW_Parameters_TypeDef* pJoyParam; /*Joystick Hardware Parameters Structure */

pJoyHwParam properties allow setting the hardware communication parameters (Bus GPIO

port, GPIO pins).

●

JOY_PortSource selects the GPIO port to be used as source for event output for the

joystick

●

JOY_PinSource is the GPIO pin for the event output

●

JOY_Select_Port selects the GPIO port to be used for the select command on the

joystick

●

JOY_Select_Pin selects the GPIO pin to be used for the select command on the

joystick

●

JOY_Right_Port selects the GPIO port to be used for the right command on the joystick

●

JOY_Right_Pin selects the GPIO pin to be used for the right command on the joystick

●

JOY_Left_Port selects the GPIO port to be used for the left command on the joystick

●

JOY_Left_Pin selects the GPIO pin to be used for the left command on the joystick

●

JOY_Up_Port selects the GPIO port to be used for the up command on the joystick

●

JOY_Up_Pin selects the GPIO pin to be used for the up command on the joystick

●

JOY_Down_Port selects the GPIO port to be used for the down command on the

joystick

●

JOY_Down_Pin selects the GPIO pin to be used for the down command on the joystick

●

JOY_Rcc_APBPeriph_GpioSel selects the APB peripheral bus that gates the select

port of the joystick

●

JOY_Rcc_APBPeriph_GpioRight selects the APB peripheral bus that gates the right

port of the joystick

●

JOY_Rcc_APBPeriph_GpioLeft selects the APB peripheral bus that gates the left port

of the joystick

●

JOY_Rcc_APBPeriph_GpioUp selects the APB peripheral bus that gates the up port of

the joystick

●

JOY_Rcc_APBPeriph_GpioDown selects the APB peripheral bus that gates the down

port of the joystick

●

JOY_Exti_IrqChannel selects the external line interrupts

●

JOY_Exti_Line selects the external interrupt line which the joystick is connected to

●

JOY_DeviceRegister if the joystick is connected to an IO expander (i.e. STMPE811) it

selects the STMPE811 device if, for example, two STMPE811s are connected to be

used as the IO expander.
