Detailed Description

Source file for nPZero Hardware Abstraction Layer (HAL)

This file contains the hardware-specific functions and configurations for the I2C communication interface. Users are required to customize these functions according to their target hardware and MCU setup.

The functions in this file serve as an abstraction layer between the IPMIC driver and the hardware-specific I2C implementation on the target system. Users should modify these functions to match the I2C peripheral and communication protocol used in their system.

Note: This file provides placeholder functions and configurations that need to be adapted to the specific hardware and MCU setup. Users must replace these placeholders with the actual implementations relevant to their system.

Warning: Incorrect configuration or improper implementation of these functions may result in I2C communication failures or unexpected behavior.

Function Documentation

◆ np0_hal_init()

np0_status_e np0_hal_init ( void )

Function to initialize hardware dependent I2C interface.

Returns: np0_status_e Status

◆ np0_hal_read()

np0_status_e np0_hal_read	(	uint8_t	slave_address,
		uint8_t	slave_register,
		uint8_t *	pData,
		uint16_t	size,
		uint32_t	timeout
	)

Function to read from registers over I2C.

Note: The device 7 bits address value in datasheet must be shifted to the left before calling the interface.; Function is blocking.

Parameters

[in]	slave_address	I2C Address for slave.
[in]	slave_register	Register Address to read.
[out]	pData	Pointer to data buffer where read data will be stored.
[in]	size	Size of data to be received.
[in]	timeout	Timeout before transmission is asserted.

Returns: np0_status_e Status

◆ np0_hal_write()

np0_status_e np0_hal_write	(	uint8_t	slave_address,
		uint8_t *	pData,
		uint16_t	size,
		uint32_t	timeout
	)

Function to write to registers over I2C.

Note: The device 7 bits address value in datasheet must be shifted to the left before calling the interface.; Function is blocking.
