Embest UNetICE JTAG Emulator and NXP ARM Development Kits from Computer Solutions

Embest UNetICE ARM In-Circuit Emulator

The Embest UNetICE, a low-cost, high-speed in-circuit JTAG emulator for ARM processors, is now available exclusively in the UK from Computer Solutions. UNetICE connects the USB or Ethernet port of a PC to the JTAG interface of the ARM target board and allows flash programming and debugging. Supporting software includes an integrated development environment (IDE) with a GCC (GNU Compiler Collection) compiler ready linked along with evaluation boards to give ‘out of the box’ program development.

With UNetICE, a user can download target programs, examine memory and registers, single-step through programs, insert multiple breakpoints, run programs in real time, and program on- and off-chip flash memory. Support is provided for two hardware breakpoints, two data breakpoints and unlimited software breakpoints.

The new unit supports all ARM7 and ARM9 kernel CPUs, and is designed for use with Windows 98/NT/2000/XP host PCs via a 10/100M Ethernet port or USB port. It includes a standard 20-pin JTAG port for connecting to the target, and will download and debug at speeds of 200-800 kbyte/s. It can either be powered from the USB port or from a separate power supply.

The Embest IDE provides a simple and versatile graphical user interface with tools for creating applications for the ARM architecture. It facilitates the management and development of projects, establishing and managing host-target communication, and running and debugging applications. It incorporates an integrated source-code editor, GNU compilers, assembler and linker, a GNU ANSI C library, and a source-level debugger. In addition to supporting the Embest IDE, UNetICE also provides support for the GNU debugger GDB, as well as the ARM ADS and SDT debugger standards and all compilers that comply with that.

A range of low-cost evaluation boards for the Philips, STMicroelectronics, Atmel, Samsung, Cirrus Logic and Intel ARM core microcontrollers are also available.

Prices for the UNetICE start at less than £450, and evaluation boards at £100.

NXP ARM Processor Development Kits

A complete low-cost development package for the NXP (Philips) LPC range of ARM processors, consisting of an evaluation and experimental board, a GCC compiler, a JTAG interface, an IDE and debugger, as well as a host of application examples, is now available from Computer Solutions.

These kits have everything an engineer needs to get started on developing ARM code as soon as the board is plugged in and the software is installed on the disk.

The Embest LPCEB2000™ range of evaluation board kits are available in versions for the LPC2114/19/24/29/94, 2131/32/38 and 2210/12/14/90/92/94, the device type being determined by the selection of a daughter board. Each kit includes full circuit diagrams, BOM, and many software examples in source code with versions to run in Flash or RAM for easy testing as well as acting as an embedded tutorial.

The motherboard incorporates a range of digital and analogue input/output facilities including serial, CAN and I2C ports, plus 2-channel A/D sampling input and PWM output. Also included are pushbutton and keypad controls, displays and the 20-pin standard JTAG port.

Software examples for the evaluation board, all in source code, include initialisation and start-up code, external interrupt test, testing of buzzers, 8-segment LED displays and keyboards, a UART drive example, control of a 595 chip via SPI, and ADC/DAC/PWM operations.

The UnetICE ARM JTAG interface connects the target board to a PC via Ethernet or USB connections and, using the Embest software package, provides debugging and flash programming capabilities. It will download target programs at speeds of over 200 Kbyte/s, and can use an external power supply or the USB interface’s supply.

The Embest IDE Integrated Development Environment for ARM offers a complete software solution for embedded ARM development. It provides a simple and versatile graphical user interface and all the tools required to create applications for the ARM architecture. Embest IDE for ARM runs under Windows 98/NT/2K/XP and supports ANSI C and the ARM assembler language.

In addition to the IDE, the software includes a project manager facility, an integrated source-code editor, a copy of the GNU compiler, assembler and linker, the GNU ANSI C library, a source-level debugger, and an ARM instruction set simulator.

The 16/32-bit LPC2000 family is based on a 1.8 V ARM7TDMI-S core operating at up to 60 MHz together with a wide range of on-chip peripherals including multiple serial interfaces, CAN, 10-bit ADCs and an external bus option. With up to 32 kbyte of RAM and 256 kbyte of on-chip flash, these controllers are designed for use in a wide range of embedded application requiring high performance and low power consumption in a cost-effective package.
