The response values are the same as get_value. Additional the changed parameter is true if the value has changed since the last callback.

Internal Functions¶

Internal functions are used for maintenance tasks such as flashing a new firmware of changing the UID of a Bricklet. These task should be performed using Brick Viewer instead of using the internal functions directly.

BrickletIndustrialDigitalIn4V2.set_bootloader_mode¶

Function ID:	235
Request:	mode – Type: uint8, Range: See meanings
Response:	status – Type: uint8, Range: See meanings

Sets the bootloader mode and returns the status after the requested mode change was instigated.

You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

The following meanings are defined for the elements of this function:

For mode:

• 0 = Bootloader
• 1 = Firmware
• 2 = Bootloader Wait For Reboot
• 3 = Firmware Wait For Reboot
• 4 = Firmware Wait For Erase And Reboot

For status:

• 0 = OK
• 1 = Invalid Mode
• 2 = No Change
