My problem is I sold all CAN stuff and just have a single interface left. So I can't perform any bench tests. However I have a car with CAN bus but never tried the interface. May I will give it a try. So I assume v1.07 doesn’t work too?

More early version I not found. I send you e-mail. Yes, v1.07. More early version I not found. I send you e-mail.

CAN speed - 250 kbits (bus load - ~16 messages in 1second) CANHacker scan exchenge data and try to send 1 messsage with period (100...1000) ms With your HEX-file (firmware_1.07.hex) recive and transmit work well (I am embarrassed only in speed selection - select 500 instead of 250) With my hex (with changed BTR0_250k 0×01 and BTR1_250k 0x1C) CANHacker in "list" can-bus normal, but when I try send 1 message periodically - CANHacker stop send any data in Recive-table. Sending data - don't work as wall. After reConnect - "listening" again work normal. Try to discribe (sorry for my English)

CAN speed – 250 kbits (bus load – ~16 messages in 1second)

With your HEX-file (firmware_1.07.hex) recive and transmit work well (I am embarrassed only in speed selection – select 500 instead of 250)
With my hex (with changed BTR0_250k 0×01 and BTR1_250k 0x1C) CANHacker in “list” can-bus normal, but when I try send 1 message periodically – CANHacker stop send any data in Recive-table. Sending data – don’t work as wall. After reConnect – “listening” again work normal.

You are fine as long as the code compiles without errors. What are your problems? I use the same WinAVR version.

What are your problems?

I want to compile project with right speed settings (250kbit/s) and Sergey's remark. I re-compile with winavr 20100110. And it works with some problems. (size of HEX-file is NOT the same as firmware_1.07.hex) What version of winAVR are you used?

Firmware will work with both types, that's only a hardware issue. Yes it is, but the DIP has a different pinning then the TQFP so schematic will not fit for the DIP.
