I recently got a board of LPC1752FBD80. I checked the circuit diagram. The CAN transceiver used is TJA1040. The TXD and RXD of the transceiver are connected to The pin P2[0] and P2[1]. Checked the datasheet of LPC1752, the two pin multiplexing functions are TXD1 and RXD1 of the serial USART1, not the designated pins of the CAN peripheral;
I want to know how to config to achieve the CAN communication function of P2[0] and P2[1], thank you very much!
