This structure contains the manufacturer's code and the unique device identifier (assigned by manufacturer). The NAME has an 8-byte structure sent by the device in an To solve such problems, we can use the device's NAME structure instead of the device address. Program above will start blocking the messages from other devices and Water Depth data will be available in the network. Is possible that the 0x19 address will be occupied by a new device, and our depth sounder will change its address to 0x25, for example. But, NMEA 2000 addresses are self-configurable, and when you add a new device to the NMEA 2000 network, it

This program may work well for many years. Will never be forwarded by the Bridge, so it is blocked.

In the code above, match() has no send() command inside, so messages with the identifier 0x1F50B19 (0x19 is an address and 0x1F50B is water depth PGN) At first glance, it seems that this task can be done with a very short program: For example, we need to block a Water Depth message (PGN 0x1F50B) from a device with address 0x19 These new functions help to create really smart programs. The heartbeat() keyword is first called from the user's program immediately after init(). It is necessary to specify the periodic interval in milliseconds Heartbeat() can be used when a program (or part of user's code) must be executed periodically. Inside init() can't send network messages because the NMEA 2000 standard prohibits sending of any messages during the first 250 milliseconds after the device'sĪddress claim procedure, and any send() calls from user's code will be ignored. Init() can be used to initialize program variables it is guaranteed to be called when the device is turned on, before any other user code. These allow creation of really smart programs.

In this firmware, the new keywords init() and heartbeat() were added to the programming language. And we are glad to present a new tool for logs viewing and conversion: CAN Log Viewer. Keywords init() and heartbeat(), and an additional format for logs is added.
