uint32_t BSP_GetVersion

(

void

)

This method returns the STM32F4xx NUCLEO BSP Driver revision.

Return values:

version,:

0xXYZR (8bits for each decimal, R for RC)

Definition at line 179 of file stm32f4xx_nucleo_144.c.

References __STM32F4xx_NUCLEO_BSP_VERSION.

void BSP_JOY_DeInit

(

void

)

DeInit joystick GPIOs.

Note:

JOY DeInit does not disable the Mfx, just set the Mfx pins in Off mode

Definition at line 794 of file stm32f4xx_nucleo_144.c.

References ADCx_DeInit().

JOYState_TypeDef BSP_JOY_GetState

(

void

)

Returns the Joystick key pressed.

Note:

To know which Joystick key is pressed we need to detect the voltage level on each key output

• None : 3.3 V / 4095
• SEL : 1.055 V / 1308
• DOWN : 0.71 V / 88
• LEFT : 3.0 V / 3720
• RIGHT : 0.595 V / 737
• UP : 1.65 V / 2046

Return values:

JOYState_TypeDef,:

Code of the Joystick key pressed.

Definition at line 811 of file stm32f4xx_nucleo_144.c.

uint8_t BSP_JOY_Init

(

void

)

Configures joystick available on adafruit 1.8" TFT shield managed through ADC to detect motion.

Return values:

Joystickstatus

(0=> success, 1=> fail)
