5 Conclusions

In this paper we presents the hardware and software

development of wireless ISO11783 parameter group number (PGN) analyzer device that is implemented in STM32F107VC Cortex-M3 development board with the Wi-Fi module.

In programming of ISO 11783 PGN analyzer, we focused on both of firmware programming and GUI on the monitoring computer and smart devices. The main role of the firmware programming is capturing CAN packet and converting to RS232 serial data format or receiving RS232 data from computer, converting it into CAN data and sending. GUI of PGN Analyzer receives RS232 data and converting to CAN packets in order to monitor them. Those converted CAN packets send to some of hidden application programs, by using one useful programming technique pipe. We used two virtual pipes for parsing and interpreting CAN packets. Finally parsed and interpreted data is shown on GUI of PGN analyzer in ISO11783 standard form. Even all converting, parsing and interpreting procedures are simultaneously made in two development boards, final displaying GUIs are different. GUIs are written by the Delphi visual programming language and HTML5. Hence our web based application is written in HTML5 which has a good opportunity to support other mobile devices.
