Running a CAN sample project on LPCXpresso LPC11C24
The LPC11C24 requires an additional 5V supply to operate the on-chip CAN transceiver. When powering the LPCXpresso board through the USB debug port only, the transceiver does not receive the full 5V. The +5VIN pin only reads 1.3V, so the transceiver does not operate correctly. I have found 2 ways to resolve this:


Use an external 5V regulated supply, connected through the +5VIN pin.
Connect the LPCXpresso to the Embedded Artists LPCXpresso Base Board.


The Base Board requires that the +5V is supplied through the USB-to-UART main power source port in addition to the debug port.
