Code description and overview

Source code for the LPC MCU on this board is available through your local NXP sales representative. Please ask them to contact the NXP Mobile Robotics team


The on board LPC MCU is used to configure the T1 and TX Ethernet PHYs for back to back operation. In addition it establishes if the T1 PHY should be the master on the T1 connection and will attempt a connection by resetting and alternating between Master and slave mode operation until the connection is made.

Therefore if two T1ADAPT boards are connected they will automatically negotiate a T1 connection. There is no specific indication which one has assumed master role.

The LPC MCU will also drive LEDs to indicate T1 data and link activity.

The TX PHY drives it's own LINK and DATA LEDs independently of the MCU.
