I2C Module

I2C Class

speed = HardsploitConstant.I2C.KHZ_100
i2c = HardsploitI2c(speed, hardsploit_api)

Parametter	Type	Range
speed	constant	HardsploitConstant.I2C.KHZ_100
hardsploit_api	instance of HardsploitAPI()

I2C Scan

This function performs an I2C address scan.

i2c.i2c_scan()

Return an array with 256 items

Signal

I2C_CLK -> A0

SDA -> A1

I2C Interact

This function interacts with an I2C device by constructing a packet from a given payload.

i2c.i2c_interact(payload)

Parametter	Type	Range
payload	array of byte	max 4000 bytes

Signal

I2C_CLK -> A0

SDA -> A1

I2C Generic dump

This function performs a dump of data from an I2C device.

i2c.i2c_generic_dump(i2c_base_address,
                     start_address,
                     stop_address,
                     max_size)

Parametter	Type	Range
i2c_base_address	byte	0 to 255 (write address = base address)
start_address	integer	0 to sizeMax-1
stop_address	integer	0 to sizeMax-1
max_size	integer	2^32 about 4giga

Tips: Number of byte for address is calculatated by sizeMax

Receive data in callback data for each packet and can be stored in database, file etc for large memory is useful.

I2C Generic import

This allow you to import data into an I2C device.

i2c.i2c_generic_import(i2c_base_address,
                       start_address,
                       page_size,
                       memory_size,
                       data_file,
                       write_page_latency)

Parametter	Type	Range
i2c_base_address	byte	0 to 255 (write address = base address)
start_address	integer	0 to sizeMax-1
page_size	integer	0 to sizeMax-1
memory_size	integer	2^32 about 4giga
data_size	string	Path of file
write_page_latency	integer	in second, 2ms = 0.002
