GPIO_CLR_CFG_EEPROM (0x1C)

The GPIO_CLR_CFG_EEPROM command clears previously saved configuration settings from the GPIO-24 adapter internal EEPROM memory. Next time you connect the adapter to PC all the pins will be not configured. The GPIO_GET_CFG and GPIO_GET_PIN_CFG commands will return GPIO_CFG_NOT_CONFIGURED (0xf) value. Use GPIO_SAVE_CFG_EEPROM command to save the current GPIO pins configuration settings.

GPIO_CLR_CFG_EEPROM Command

Go to Response

Byte 0 GPIO_CLR_CFG_EEPROM Command ID (0x1C).
Byte 1 ECHO Echo to associate a command with the response.
Bytes 2..7 Reserved Reserved (must be 0).

Command is an 8-byte array of the following format:

Byte 0: GPIO_CLR_CFG_EEPROM (0x1C)

This byte contains command ID (command type). It should be set to 0x1C.

Byte 1: ECHO

This byte is used to associate a response received from GPIO-24 adapter with a specific command. Response will contain exactly the same value in its echo byte.

Bytes 2..7: Reserved

These bytes are reserved for future usage and have to be set to 0.

For convenience GPIO_CLR_CFG_EEPROM_CMD structure is declared in reports.h file.

GPIO-24 adapter sends GPIO_CLR_CFG_EEPROM response after command execution.

GPIO_CLR_CFG_EEPROM Response

Go to Command

Byte 0 GPIO_CLR_CFG_EEPROM Response ID (0x1C).
Byte 1 ECHO Echo to associate a command with the response.
Byte 2 ST Command execution status.
Bytes 3..7 Reserved Reserved

Response is an 8-byte array of the following format:

Byte 0: GPIO_CLR_CFG_EEPROM (0x1C)

Response ID (response type). This byte will contain 0x1C.

Byte 1: ECHO

This byte is used to associate a response received from GPIO-24 adapter with a specific command. Response will contain exactly the same value in its echo byte.

Byte 2: ST

Status of the command execution:

  • GPIO_ST_SUCCESS (0x0) – The GPIO pins configuration settings have been cleared.

Bytes 3..7: Reserved

These bytes are reserved for future usage.

For convenience GPIO_CLR_CFG_EEPROM_RSP structure is declared in reports.h file.
