Hello. We have downloaded from your site library driver MSCAN_DRIVER to work with CAN bus controller KEA128. We use the debug board TRK-KEA128. The program is made of examples taken from the description of the library. The program periodically sends a data packet. The two-wire line with contact CANL, CANH to pay tribute to the analyzer CAN network. As a result, the parser does not record any data packets. Viewed on an oscilloscope. With the controller chip transmitter / receiver are PC339 data. After the chip is nothing. We tried as a ready example, bundled with a library, the same result. I do not tell you what could be the reason? We put the project. Thanks in advance.

I have some questions regarding your application:
Have a great day. :smileyhappy:
Hello. We believe , found the cause of failure. Output STB is not pulled to the ground ! The resistor R66 (4.7 ohm ) , which is the diagram in pdf on the card has not been set in TRK-KEA! Soldered resistor and it worked . I can not understand why he was not there ?!

I am glad to know your application works properly.
Indeed, based on the TRK-KEA128 schematic , the R66 is not populated.
It is necessary to add the resistor mentioned in case you want to use that module.
Have an excellent day. :smileyhappy:
