Hello,
I programmed a LPC11C24 to read analog ports and send the values via CAN. Everthing worked fine. Now I cut the board and wanted to use just the Target board. I supply it with 5V and 3.3V, but now CAN isn't working. Do I have to enable something?

Believe it or not, LPC11C24 requires a 5V supply voltage for its 5V CAN-transceiver at pin 20   :O  :quest:   :O

NXP has no 3.3V CAN-transceiver  :)

With connected LPC-link this is done by J4-18 as shown in schematic...
