Atlas 300I Inference Card Earlier than 1.0.11 DCMI API Reference (Models 3000, 3010) 13

dcmi_get_device_voltage Prototype

Syntax

int dcmi_get_device_voltage (int card_id, int device_id, unsigned int *pvoltage)

Function

Queries the chip voltage.

Parameter Description

Parameter	Input/Output	Type	Description
card_id	Input	int	ID of the Atlas 300I inference card. Query the supported IDs by referring to dcmi_get_card_num_list Prototype.
device_id	Input	int	Chip ID ranging from 0 to 3. Query the actually supported range by referring to dcmi_get_device_num_in_card Prototype.
pvoltage	Output	unsigned int *	Chip voltage: The unit is V and the precision is 0.01 V. It is a 16-bit unsigned short integer, in little endian mode. The calculation formula for baseboard management controllers (BMCs) is value = reading x 0.01.

Description

card_id

Input

int

ID of the Atlas 300I inference card. Query the supported IDs by referring to dcmi_get_card_num_list Prototype.

device_id

Input

int

Chip ID ranging from 0 to 3. Query the actually supported range by referring to dcmi_get_device_num_in_card Prototype.

pvoltage

Output

unsigned int *

Chip voltage: The unit is V and the precision is 0.01 V. It is a 16-bit unsigned short integer, in little endian mode.

The calculation formula for baseboard management controllers (BMCs) is value = reading x 0.01.

Return Value

Type	Description
int	Results: If the return value is 0, the operation is successful. If the return value is an error code less than 0, the operation fails.

Calling Example

int ret = 0;

unsigned int  voltage;

int card_id = 0x56;

int device_id = 0;

ret = dcmi_get_device_voltage(card_id, device_id, &voltage);

if(ret != 0) {

//todo: records logs.

return ret;
