R6 prevents LIN packages to arrive

robertaramar opened this issue · comments

Hi,

I have setup the hardware on a breadboard connected to the desk and I got everything working fine. However, I do NOT receive LIN frames when using R6 to pull-up the D2 line to 5V. Admittedly, I am using a different transistor. The one I had available is a BC547 instead of the 2N3904.

As I do not have enough background in electronics design, I that an issue? Is that caused by my different transistor?

Regards,

Robert

End-User problem. BC547 - compared to 2N3904 - has E and C switched. So the transistor was wrongly inserted. Funnywise, it worked that way as long as I didn't insert the R6.
Problem solved.
