Functions

	return the typical execution time for the given command
ATCA_STATUS	calib_execute_send (ATCADevice device, uint8_t word_address, uint8_t *txdata, uint16_t txlength)
ATCA_STATUS	calib_execute_receive (ATCADevice device, uint8_t device_address, uint8_t *rxdata, uint16_t *rxlength)
ATCA_STATUS	calib_execute_command (ATCAPacket *packet, ATCADevice device)
	Wakes up device, sends the packet, waits for command completion, receives response, and puts the device into the idle state.

Detailed Description

Implements an execution handler that executes a given command on a device and returns the results.

This implementation wraps Polling and No polling (simple wait) schemes into a single method and use it across the library. Polling is used by default, however, by defining the ATCA_NO_POLL symbol the code will instead wait an estimated max execution time before requesting the result.

Function Documentation

calib_execute_command()

ATCA_STATUS calib_execute_command	(	ATCAPacket *	packet,
		ATCADevice	device
	)

Wakes up device, sends the packet, waits for command completion, receives response, and puts the device into the idle state.

Parameters

[in,out]	packet	As input, the packet to be sent. As output, the data buffer in the packet structure will contain the response.
[in]	device	CryptoAuthentication device to send the command to.

Returns

ATCA_SUCCESS on success, otherwise an error code.

calib_get_execution_time()

ATCA_STATUS calib_get_execution_time	(	uint8_t	opcode,
		ATCADevice	device
	)

return the typical execution time for the given command

Parameters

[in]	opcode	Opcode value of the command
[in]	ca_cmd	Command object for which the execution times are associated

Returns

ATCA_SUCCESS
