I/O Handler LPCXpresso board with Link2 On Board Debug

The LPCXpresso LPC11U37H board is an extended variant of the standard LPCXpresso V2 board design, designed to allow evaluation of the I/O Handler functionality available on the LPC11U37HFBD64.

The I/O Handler is a software library-supported hardware engine that can be used to add performance, connectivity and flexibility to system designs. The I/O Handler can emulate serial interfaces such as UART, I2C, and I2S with no or very low additional CPU load and can off-load the CPU by performing processing-intensive functions like DMA transfers in hardware.
