OBD secondary development tool - GCAN

With the car playing an increasingly important role in the real life of human beings, there are more and more people's attention on all aspects of the car. The Speed Party pays attention to the displacement and horsepower of the car engine. The aesthetic party pays attention to the appearance and interior decoration of the car. The entertainment party enjoys the ultimate audio and video experience brought by the car audio screen. But at the same time, we should not forget that the car is used to drive after all. This is the first problem that needs to be considered as a car. Here, we have to mention the control bus system of the car. Without a bus with good performance, no matter how good the car is, it can't release all its energy.


 OBD interface in car
At present, most of the cars basically only use two kinds of bus systems, namely the local interconnect protocol bus LIN and the controller area network CAN bus. In addition, the high-speed fault-tolerant network protocol FlexRay, most for automotive multimedia and navigation, and Bluetooth compatible with computer networks, Wireless network technologies such as wireless LANs are also under development, but the dominant position of CAN and LIN is still unable to move. Here's a briefly introduce about them:
The LIN bus is a low-cost serial communication bus, which is mainly used for control of electric windows and doors, seat adjustment, lighting, etc. In addition, it can exchange information with other systems of the CAN bus to achieve richer functions. . LIN has become an international standard and is accepted by most automakers and component manufacturers.

In the current automotive bus network market, the dominant bus is CAN bus. It is a serial data communication protocol bus developed by Bosch GmbH in Germany in the early 1980s to solve the problem of data exchange between many control and test instruments in modern automobiles. Its short-frame data structure, non-destructive bus arbitration technology and flexible communication methods adapt to the real-time and reliability requirements of the car. Its advantages are highlighted by the fast data transmission speed (max baud rate up to 1Mbps), long data transmission distance (up to 10KM), multi-connected node devices (one CAN bus can connect 110 node devices at the same time), anti-interference Superior ability (can work normally under strong external interference environment, even if there is a problem with one node, it will not affect the whole bus system), not only the control of the car, artificial intelligence, industrial automation production, fire engine linkage The CAN bus was chosen, which is why CAN bus engineers and related practitioners are so optimistic about it.

OBD secondary development tool

Having said that, the CAN bus used in the car is not static. Sometimes people need to diagnose or upgrade it, but the problem is also coming. The owner who wants to develop the car-related development diagnosis is not necessarily familiar with the CAN bus. The principles and diagnostics upgrade methods, then what do they need to do? Here, there are the following methods for them to choose:
1. If the owner has a certain knowledge of CAN bus, then they can purchase the USBCAN series CAN bus analyzer from GCAN to carry out the secondary development of the OBD of the car. The
USBCAN-OBD can be directly connected to the OBD socket of the car, through ECANTOOLS, etc. The relevant software queries out the specific CAN bus data of the car, and then parses the data through its own capabilities. If the OBD port of the car has a gateway, it also needs to be directly wired from the inside, bypass the gateway for data query work, and then perform data cracking. However, the disadvantages of this method are also obvious. If the owner is not familiar with the CAN bus, it is necessary to learn and understand The CAN knowledge can be done by hand, and the project takes a long time. In some projects that have strict requirements on time, I do not recommend this method.

2. The second method is to directly purchase
GCAN-600 and its derivatives of OBD secondary development tool of GCAN. The GCAN-600 OBD secondary development tool is specially developed for automotive electronics users and car networking platform vendors. A software-service developer's tailor-made module for automotive electronics development and car decoding. Equipped with the GCAN-600 OBD secondary development tool, developers can quickly complete the integration and development of related products without knowing the knowledge of CAN bus data and automotive CAN protocol. There is no need to decode the car, which will save a lot of manpower and time. The GCAN-600 OBD secondary development tool is compact and compact. It uses high-quality chips, high integration, low-power circuit design, easy to use, and fast response. The module can support most models on the market, support real-time data and statistics of the car, and the data stability is high. Easy to integrate using a standard UART interface connection, AT command control is easy to use.

In addition, in order to better integrate the GCAN-600 OBD secondary development tool into the owner's original system, GCAN Technology also uses it as the core blueprint and peripheral peripheral circuits to form the GCAN-600-V2 and V3 versions. The development board makes the debugging development work more convenient and faster.
