The following is the newly developed host computer software screenshot display (updated in October 18, 2016).

1. listen to the standard CAN data, which is the data detected by ISO15765 CAN.

2. expand the CAN data, which is the extended CAN data detected by ISO15765 CAN.

3. K line data interception, map for ISO14230 KWP2000 data interception.

4. K line data listening to the.ISO14230 KWP2000 data front data is the address activation process 55 detection rate KW1 KW2 KW2 to take the reverse 70 to the car, the car reply CC confirmed activation success!

5.K-line data interception, ISO9141 data, this data is not KWP2000 format, with 68 6A query 48 6B reply. Common in Jetta Japanese car MITSUBISHI engine BYD and other vehicles.

6. K line data with time interval detection, annotated the time interval between bytes, time interval between frame data, helps OBD developers to master accurate timing, and the written program will not fail to measure the car because of the time problem.

6. send the listener data to the validity of the vehicle validation command.

The following is the source code display, which provides all the host computer's lower machine source code, no library, completely open source does not hide!

1. PC source code VS2010 platform to prepare, provide complete engineering package engineering source code.

2, STM32 source hardware microcontroller source code, the complete project is completely open source. Technical questions can teach you, how to play!

The following introduction is to update the software before the operation instructions!

OBD interface analyzer is an integrated product of integrated CAN analyzer and K line analyzer. It is a tool for developing OBD products, such as a window elevator lock device driver computer, remote automobile diagnosis and so on. The CAN analysis function has automatic rate recognition for OBD rate and dual filtering ID. It brings convenience to remote control state, vehicle speed condition and various vehicle condition analysis.meanwhileSupport single line CAN listening. Support dual line CAN data transmission. K-line analysis, which can completely present KWP2000 protocol, single point protocol and so on, can present the time interval between data between bytes and data packets. It provides strong data support for writing K-line protocol and ensures the stability of product development.

Why the CAN analyzer is not enough, according to the standard of UDS ISO14229, each car manufacturer is contending for the unification of the various mountain heads, and the current models are both domestic and joint ventures. The K-line occupies half of the river. UDS ISO14229 covers the definition of CAN and K-line.

Is K-line difficult? Is CAN hard? Is it difficult to analyze OBD data?

Not difficult, K-line is a changed reference level serial communication, CAN like a car with a license plate on a high speed road, OBD data is the two brothers in front of you, you ask me if I have two and other bus, it is sure, it is not popular is eliminated, like the J1850, that is not everyone's J line, not this time, no J line, not this time It is the waveform signal that PWM modulates the pulse width, and the structure of egg pain finally goes to ruin. So the physical scope of OBD development is very small, simple reading data, as long as you read junior high school, understand one yuan two times equation, you can analyze. Y=KX when you know whether Y and X can get K (for example, the speed of the video is fifth sixth bytes divided by 4).

OK Let's look at the function of the product.
