Product Description

The jBoard-X2 is an industrial-strength embedded system utilizing the vast capabilities of the NXP LPC1768 (ARM Cortex M3) processor.

The LPC176x/5x are Cortex-M3 microcontrollers for embedded applications featuring a high level of integration and low power consumption at frequencies of 100 MHz (120 MHz for LPC1769 and 1759). Features include up to 512 kB of flash memory, up to 64 kB of data memory, Ethernet MAC, USB Device/Host/OTG, 8-channel DMA controller, 4 UARTs, 2 CAN channels, 3 SSP/SPI, 3 I2C, I2S, 8-channel 12-bit ADC, 10-bit DAC, motor control PWM, Quadrature Encoder interface, 4 general purpose timers, 6-output general purpose PWM, ultra-low power Real-Time Clock with separate battery supply, and up to 70 general purpose I/O pins. The LPC176x are pin-compatible to the 100-pin LPC236x ARM7 series.

The NXP LPC1700 microcontroller series offers the following features:

  • Support for communication peripherals including 10/100 Ethernet, USB On-The-Go/Host/Device and two CAN interfaces, all of which can operate simultaneously and without bus contention
  • A true 12-bit analog-to-digital converter (ADC) and 10-bit digital-to-analog converter (DAC)
  • Fast-Mode Plus (1 Mb/s) I2C bus, in addition to 4 UARTs, 3 SPI/SSP buses and an I2S bus
  • Real-Time Clock operating at less than 1 uA
  • A Memory Protection Unit (MPU) allowing memory regions to be defined as read-only and protect them from corruption
  • A Quadrature Encoder Interface and Motor Control Pulse Width Modulator (PWM) for flexible, powerful motor control
  • Revision 2 Cortex-M3 core with enhanced power down capabilities, including Wake-up Interrupt Controller
  • Pin compatibility with the NXP LPC2300 ARM7 microcontrollers series

The board includes:

  1. Two CAN Bus Interfaces
  2. One RS232 Port
  3. One RS485 Port
  4. On-Board Flash Memory for parameter storage

The Definitive Guide to ARM Cortex-M3 and Cortex-M4 Processors

by Joseph Yiu

the-definitive-guide-to-arm-cortex-m3-and-cortex-m4-processors.jpgThis new edition has been fully revised and updated to include extensive information on the ARM Cortex-M4 processor, providing a complete up-to-date guide to both Cortex-M3 and Cortex-M4 processors, and which enables migration from various processor architectures to the exciting world of the Cortex-M3 and M4.

This book presents the background of the ARM architecture and outlines the features of the processors such as the instruction set, interrupt-handling and also demonstrates how to program and utilize the advanced features available such as the Memory Protection Unit (MPU).

Chapters on getting started with IAR, Keil, gcc and CooCox CoIDE tools help beginners develop program codes.  Coverage also includes the important areas of software development such as using the low power features, handling information input/output, mixed language projects with assembly and C, and other advanced topics.

  • Two new chapters on DSP features and CMSIS-DSP software libraries, covering DSP fundamentals and how to write DSP software for the Cortex-M4 processor, including examples of using the CMSIS-DSP library, as well as useful information about the DSP capability of the Cortex-M4 processor
  • A new chapter on the Cortex-M4 floating point unit and how to use it
  • A new chapter on using embedded OS (based on CMSIS-RTOS), as well as details of processor features to support OS operations
  • Various debugging techniques as well as a troubleshooting guide in the appendix
  • Topics on software porting from other architectures
  • A full range of easy-to-understand examples, diagrams and quick reference appendices
