CHAPTER 1: OVERVIEW

1. Introduction to the chapter

Thank you for choosing an OpenOCD debugger manufactured by OLIMEX LTD. This document

provides information about two of the ARM debuggers manufactured by OLIMEX LTD – ARM-

USB-OCD and ARM-USB-OCD-H.

ARM-USB-OCD and ARM-USB-OCD-H are very similar in features and hardware design.

Because of that when one of them is mentioned in this document it is safe to assume that the

information applies for both debuggers, unless it is specifically stated otherwise.

1.1 Features

The debuggers have the following features:

•

Debug all ARM microcontrollers with JTAG interface supported by OpenOCD

•

Use ARM's standard 2×10 pin JTAG connector

•

Support ARM targets working in voltage range 2.00V – 5.00V (1.65V – 5.00V for ARM-

USB-OCD-H)

•

Supported by the open-source community and OpenOCD debugger software

•

Automatic powering via the JTAG to your target board with up to 200mA at 5V

•

Able to power a target board via a standard DC barrel jack; cable for the external powering

included – 2.1×5.5×14mm female connectors at both ends

•

Downloadable Windows installer for full featured and open source tools as alternative to the

commercial ARM development packages: GCC C compiler, OpenOCD debugger and

Eclipse IDE.

•

Work with IAR EW for ARM via GDB server

•

Work with Rowley Crossworks IDE

•

Work with CooCox IDE

•

Supported in Windows, Linux and Mac

•

Dimensions (50×40)mm ~ (2×1.6)" + 20 cm ~ (8") JTAG cable – ribbon cable included

ARM-USB-OCD-H has these specific features over the ARM-USB-OCD:

•

High speed USB 2.0 with lower latency time, RTCK adaptive JTAG clock up to 30Mhz and

higher throughput achieve x3-x5 times faster programming speed than ARM-USB-OCD

•

Works with lower voltage targets (down to 1.65V); the ARM-USB-OCD can't debug targets

working at voltage levels lower than 2V.

ARM-USB-OCD has this specific feature over ARM-USB-OCD-H:

•

A jumper that allows you to change the voltage provided to the target. It can power 5V, 9V

or 12V targets; ARM-USB-OCD-H can provide only 5V to the target.

变频器与电机的距离问题

1.在高度自动化的工厂里，可以在中心控制室监控所有的控制设备，变频器系统的信号也要送到中控室，变频器的位置若在中心控制，总控台与变频器之间，可以直接连接，通过0-5/10V的电压信号和一些开关量信号进行控制。但是，变频器的高频开关信号的电磁辐射对弱电控制信号会产生一些干扰，因此也不一定要美观整齐，把变频器放在中心控制室内。如果变频器与中心控制室距离远一点，可以采用4-20mA的电流信号和一些开关量...[详细]
