7.12.1 M1X22_GPIO_NUMBER
Description
This is the list of GPIO pin definitions.
Prototype
typedef enum
{
M1X22_GPIO_NUM_4 = 0x10, /* GPIO-4 */
M1X22_GPIO_NUM_5 = 0x20, /* GPIO-5 */
M1X22_GPIO_NUM_6 = 0x40, /* GPIO-6 */
M1X22_GPIO_NUM_7 = 0x80 /* GPIO-7 */
}
M1X22_GPIO_NUMBER;
Parameters
Name Value Description
M1X22_GPIO_NUM_4 0x10 GPIO4.
M1X22_GPIO_NUM_5 0x20 GPIO5.
M1X22_GPIO_NUM_6 0x40 GPIO6.
M1X22_GPIO_NUM_7 0x80 GPIO7.
7.12.2 M1X22_GPIO_CONFIG_COMMAND
Description
This is the GPIO configuration command. The GPIO can be configured using the
M1X22_GPIO_CONFIG_SET
command. Its configuration can be read using M1X22_GPIO_CONFIG_GET
command. The GPIO must be enabled using the M1X22_GPIO_CONTROL IOCTL for the new
configuration to take effect.
Prototype
typedef enum
{
M1X22_GPIO_CONFIG_GET = 0, /* GPIO config GET */
M1X22_GPIO_CONFIG_SET = 1 /* GPIO config SET */
}
M1X22_GPIO_CONFIG_COMMAND;
Parameters
Name Value Description
M1X22_GPIO_CONFIG_GET 0 Read the GPIO configuration.
M1X22_GPIO_CONFIG_SET 1 Write the GPIO configuration.
