I am using truestudio and cubemx with STM32F103C8T6. I am trying to use canbus. If I connect the cantx and canrx pins on A12 and A11 (as shown in attached cubemx file), I get an output that looks like a can frame, but has peak voltage of 400mV.
cubemx file and a zip of project is attached, does anyone have any idea what could be the problem?
there were some resistors for usb on the board, but I removed them. I am programming with stlink v2 with swd
also, it is running at something like 83 kHz. I used this (http://www.bittiming.can-wiki.info/) website to calculate values, but I'm not sure what to put for clockrate since cubemx clock configuration doesn't mention canbus anywhere and looking at all the datasheets and guides I could I couldn't figure out what clock the canbus uses.
Does anyone know where I can find what clock the canbus is using?
