WebCAN bus errors can occur for several reasons - faulty cables, noise, incorrect termination, malfunctioning CAN nodes etc. Identifying, classifying and resolving such CAN errors is … Web10. Turns out the answer should have been obvious from the waveforms above. When TX goes low, so does RX. But when TX goes high, RX takes more than 1us to rise again. That's more than a whole bit time! CAN cannot work under these conditions. The reason RX lags behind TX would have been obvious with a proper oscilloscope, rather than a simple ...
WebOnce you have one, insert the module into the scope and turn it on. You will have to get your signal to display on screen and then turn on the Bus option. The main parts to setup are the correct scope channels and the threashold levels. Your signal should begin to decode at this point. Select your bit rate and you should be alsmost done.
