INTRODUCTIONLPC-H3131 board includes powerful LPC3131 180 MHz ARM microcontroller, with 4 Gb NAND FLASH, 256 Mb SDRAM, which gives user opportunity to run Embeded Linux operation systems. In addition there is audio codec, which gives chance to be made audio signal processing; USB_OTG; USB to UART; mini SD/MMC card connector. There are plenty of GPIOs on extension headers where you can connect your additional circuits.

ELECTROSTATIC WARNING

The LPC-H3131 board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board.

BOARD USE REQUIREMENTS

Cables: The cable you will need depends on the programmer/debugger you use. If you use ARM-USB-TINY or ARM-USB-TINY-H, you will need USB A-B cable and if you use ARM-USB-OCD, you will need RS232 and USB A-B cable.

Hardware: One of OLIMEX Programmers/Debuggers – ARM-USB-OCD, ARM-USB-TINY or ARM-USB-TINY-H, but we do not offer projects with this programmers.

SPIThe SPI module is used for synchronous serial data communication with

other devices which support the SPI/SSI protocol. Examples are memories, cameras, or WiFi-g. The SPI/SSI-bus is a 5-wire interface, and it is suitable for low, medium, and high data rate transfers.

This module has the following features:

– Supports Motorola SPI frame format with a word size of 8/16 bits.

– Texas Instruments SSI (Synchronous Serial Interface) frame format with a word size of 4 bit to 16 bit.

– Receive FIFO and transmit FIFO of 64 half-words each.

– Serial clock rate master mode maximum 45 MHz.

– Serial clock rate slave mode maximum 25 MHz.

– Support for single data access DMA.

– Full-duplex operation.

– Supports up to three slaves.

– Supports maskable interrupts.

– Supports DMA transfers.

I 2 C-bus master/slave interface The LPC3131 contains two I2C master/slave interfaces.

This module has the following features:

– I2C-bus interface 0 ( I2C0): I2C0 is a standard I2C-compliant bus interface with open-drain pins. This interface supports functions described in the I2C-bus specification for speeds up to 400 kHz. This includes multi-master operation and allows powering off this device in a working system while leaving the I2C-bus functional.

– I2C-bus interface 1 (I2C1): I2C1 uses standard I/O pins and is intended for use with a single-master I2C-bus and does not support powering off of this device. Standard I/Os also do not support multi-master I2C implementations.

– Supports normal mode (100 kHz SCL).

– Fast mode (400 kHz SCL with 24 MHz APB clock; 325 kHz with12 MHz APB clock; 175 kHz with 6 MHz APB clock).

– Interrupt support.

– Supports DMA transfers (single).

– Supports DMA transfers (single).

– Master transmitter

– Master receiver

– Slave transmitter

– Slave receiver
