It can be dangerous to cycle in the city. This expresses what the speaker believes is a general truth or known fact, or a strong possibility. It could/may be dangerous to cycle in the city. This does not express a general truth. The speaker is only expressing a weak possibility. It ’s dangerous to cycle in the city. This expresses a real fact using the present simple. The speaker is certain and no modality is used. Requests When we make requests, we can use can or could (but not may). Could is more polite than can: Can you call back later? I’m busy now. Could you call back later? I’m busy now. Teachers and parents often use can and could in requests: Can you open your books at page 34, please. Can you please refrain from chewing gum. Could you just sit down and listen! Can, could or may: typical errors • Could in the present only expresses weak possibility. Can expresses strong possibility: I can travel in July because my exams will definitely be finished at the beginning of that month. (strong possibility) I could travel in July because my exams will probably be finished at the beginning of that month. (weak possibility) • We don’t normally use could to talk about general truths which refer to the present time. We use can instead: Not everyone can afford to buy organic food. Not: Not everyone could afford … • We use could, not can, to express future possibility. Can expresses that we are certain of something: Working in London next summer could be a great experience.

Data protocol for motor vehicles CAN FD (Controller Area Network Flexible Data-Rate) is a CAN FD versus classic CAN [ ] The primary difference between the classical CAN (Controller Area Network) and CAN FD is the Flexible Data (FD). Using CAN FD, Electronic Control Units (ECUs) are enabled to dynamically switch between different data rates and longer or shorter messages. Faster data speed and more data capacity enhancements results in several system operational advantages compared to classic CAN. Commands issued by the executing ECU software reach the output controller much faster. CAN FD is typically used in high performance ECUs of modern vehicles. A modern vehicle can have more than 70 ECUs that use CAN FD to exchange information over the CAN bus when the engine is running or when the vehicle is moving. In CAN FD, it's possible to use the 11-bit identifier (FDBF FD base frame Format) or the 29bit identifier (FEFF FD extended frame Format). The message payload size has been increased to 64 bytes of data in each CAN-frame / message, compared to only 8-bytes in the classic CAN frame. A frame is a message transmitted as a sequence of binary bit-pattern. In CAN FD, the data rate (i.e. number of bits transmitted per second) is increased to be 5 to 8 times faster than the classic CAN (5 to 8Mbit/s for the data payload only, the arbitration bit rate is still limited to max 1Mbit/s for compatibility). Data rate depends on the topology of the bus network and the used CAN-FD bus l...

Level: beginner Possibility and impossibility We use could to show that something is possible, but not certain: They could come by car. (= Maybe they will come by car.) They could be at home. (= Maybe they are at home.) We use can to make general statements about what is possible: It can be very cold here in winter. (= It is sometimes very cold here in winter.) You can easily get lost in this town. (= People often get lost in this town.) We use can't or cannot to say that something is impossible: That can't be true. You cannot be serious. Level: intermediate We use could have to make guesses about the past: It's ten o'clock. They could have arrived by now. Where are they? They could have got lost. We use could to make general statements about the past: It could be very cold there in winter. (= It was sometimes very cold there in winter.) You could easily get lost in that town. (= People often got lost in that town.) We use can't have or couldn't have to say that a past event was impossible: They know the way here. They can't have got lost! If Jones was at work until six, he couldn't have done the murder. Ability Level: beginner We use can and can't to talk about someone's skill or general abilities: She can speak several languages. He can swim like a fish. They can't dance very well. We use can and can't to talk about the ability to do something at a specific time in the present or future: I can see you. Help! I can't breathe.

CAN bus stands for Controller Area Network Communication and consists of two electrical wires called CAN_Low and CAN_High. The information within each vehicle is transmitted from and to We have prepared a simple introduction to the CAN bus. Several topics have been covered, to give you the best explanation of the CAN protocol. While working on the article, we combined the knowledge from our top experts within the company, as well as non-expertise team members. Why? The idea was to write a professional but simple guide introduction to the CAN bus for everyone, no matter how much experience you have. In conclusion, it does not matter if you have no knowledge about the CAN bus protocol whatsoever or if you are already a pro. This simple guide intro to CAN bus will give you all the information needed. What is CAN bus? CAN bus is a set of two electrical wires in the car network (CAN_Low and CAN_High), where the information is sent to and from ECUs. The network that allows ECUs to communicate is called Controller Area Network (CAN). The CAN bus is a serial communication bus, designed for robust performance within harsh environments, primarily in industrial and automotive applications. It is a vehicle bus standard that allows microcontrollers and devices to communicate with each other. CAN bus is one of the protocols used in The CAN bus system Depending on the type of the car, it can have up to 70 ECUs (Electronic Control Units) and each of them needs to be shared with other part...
