The LPCXpresso11U37H board is an extended variant of the standard LPCXpresso V2 board design, designed to allow evaluation of the I/O Handler functionality available on parts such as 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.
The most notable changes in the design of the LPCXpresso11U37H board are:
LPCXpresso V2 boards have different PMOD support depending on their target applications. Further information below:
The LPCX11U37H I/O handler kit uses the PMOD interface connections for the specialized I2C and DALI daughter cards, with the LPCXpresso-side connector being male rather than female. In the LPCXpresso11U37H only version (available July 2014) does not have a PMOD connector fitted, so one can be added for use with standard PMOD-compatible cards. .
