Ignition Sensing
The Karbon series come with several advanced features that help you make the most out of your applications. One of these features is ignition sensing, a feature that allows you to control your Karbon unit through your vehicle.
So how exactly does ignition sensing work and how is it useful to you?
Ignition sensing on the Karbon series works such that the unit can be powered on or off depending on whether the vehicle itself is on or off. For example, if the vehicle ignition is turned on, the PC unit will power on. Likewise, when ignition is turned off, the PC unit will power off. This process of events can be seen in the timeline below:
The timeline of events diagram shows ignition power state and the PC power state. Going from left to right, you can see that when the ignition power state is “On” (or the vehicle is turned on), the PC power state enters a PC “boot” time state where the PC boots on. This state lasts only a few seconds, before entering the PC power “on” state, meaning the PC unit is turned on.
When the ignition power state is “Off” (or the vehicle is turned off), the PC power state enters a “countdown active” delay before turning off completely. This delay before the PC unit turns off can be adjusted through OnLogic’s microcontroller (MCU) and can range from seconds to hours.
Ignition Sensing is found on the 5-pin power input terminal block for Karbon 700, or the 3-pin power input for Karbon 300, pictured below, where pin 1 is for ignition power on/off.
Ignition timing delays can be modified through serial commands to the MCU using python. The Karbon series come with their own module for interfacing with hardware devices called Pykarbon. To learn about how to use serial commands to change your timing delays on ignition, visit OnLogic’s github page on the Pykarbon module.
CAN Bus FAQ
The CAN bus on the Karbon series computers can be modified to fit your applications. Here are some of the frequently asked questions regarding the CAN bus feature.
Q: How do I know which port to use?
A: Messages may be sent by writing to the CAN virtual serial port, like this:
std 123 4 11223344 data
The syntax is: [std | ext] [id] [length] [data] [data | remote]
The Karbon series computers additionally support doing some of the legwork for you, and support using a terminal command to interpret and send a packet:can-message 123 11223344
The syntax is: can-message [id] [data]
So just to be clear, you use the first syntax on the CAN serial port, and the second syntax on the serial terminal.
Q: How do I receive data?
A: CAN messages are delivered to the CAN virtual serial port. If you are monitoring this port in with a serial terminal, you will see the data printed out in the terminal.
Q: Can I set the baud rate?
A: Yes! This is a configuration setting, so you’ll need to access the serial terminal. From there, you have two available commands. The first is:can-autobaud
This command will attempt to detect the baud rate and propagation delay of your CAN bus. It does this by sending messages with ID 7FF, and watching for acknowledgement — so it may not work in every setting. Which is when you want to use the second command:set can-baudrate 800
The syntax is:set can-baudrate [rate](rate is in thousands)
In both cases, you can check if the baud rate was set correctly using config. Don’t forget to save your settings with save-config to ensure that it will persist after a power loss.
Q: Help! Something is terribly broken, how do I reset?
A: If things have stopped working quite right, you can reset the Karbon’s microcontroller and CAN controller by performing a hard power cycle (completely disconnect the system from power). Make sure you shut down normally first!
If something is ever really, really broken, you can force the Karbon series computer to boot in recovery mode by depressing the settings switch while plugging the system in. From here, you should be able to completely re-flash the firmware.
Q: What CAN standards do the Karbon computers support?
A: The Karbon series computers have a CAN 2.0B controller.
