PCA9532_Init()

FctERR PCA9532_Init	(	const uint8_t	idx,
		I2C_HandleTypeDef *const	hi2c,
		const uint16_t	devAddress )

Initialization for PCA9532 peripheral.

Parameters

[in]	idx	- PCA9532 index
[in]	hi2c	- pointer to PCA9532 I2C instance
[in]	devAddress	- PCA9532 device address

Returns

FctERR - error code

PCA9532_Init_Single()

FctERR PCA9532_Init_Single

(

void

)

Initialization for PCA9532 peripheral.

Warning

In case multiple devices (defined by I2C_PCA9532_NB > 1), you shall use PCA9532_Init instead

Returns

FctERR - error code

Here is the call graph for this function:

PCA9532_Read()

FctERR PCA9532_Read	(	I2C_slave_t *const	pSlave,
		uint8_t *	data,
		const uint16_t	addr,
		const uint16_t	nb )

I2C Read function for PCA9532.

Warning

When Auto-Increment flag is set (AI = 1) and a read sequence is initiated, the sequence must start by reading a register different from the INPUT0 register.

Parameters

[in,out]	pSlave	- Pointer to I2C slave instance
[in,out]	data	- pointer to read to
[in]	addr	- Address to read from
[in]	nb	- Number of bytes to read

Returns
