USB-CAN Bus
The purpose of this project is a simple and easy to use USB <> CAN bus interface. Heart of the circuit is an Atmel AVR ATmega162 microcontroller which controls the Communication between FTDI FT245BM USB to parallel converter and Philips SJA1000 Stand-alone CAN bus controller.
The SJA1000 is memory mapped into memory space of the AVR, which reduces data and address line handling and increases data transfer speed.
An FT245BM handles all USB communication and provides data transfer from and to PC application. An extra EEPROM can store the multi device template for the FT245BM.
A Philips PCA82C250/251 works as CAN controller interface.
Firmware is written in C, compatible to latest compiler version WinAVR.
The firmware is now compatible to run on a CANDIP module. The download include a pre-compiled firmware file to flash into a CANDIP module. Both pins for LED connection remaining the same.
See the CANDIP homepage for detail of the required hardware CANDIP/M162 .

hi,
i have a question about yourCANBUS software.
your CANBUS software support to DS401 CANopen protocol.
thanks.

My Software doesn’t support any specific CAN protocol.
It’s just a simple example to show and send CAN bus data, no further evaluation of these data is done.

are there any insructions/documentation for the CAN-Control software?

When I use can-usb for read, sametimes blink red diod.
Why?

Red LED means an error was detected.
But there are various reason for errors. So may you read the ECR register to see what was the last error.
