国外开源逻辑分析仪Openbench,32通道的.70MHz的采样速度

什么都不说。先看图，有源码及PCB文件，哪位有兴趣做出来玩玩？

Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. Download the source and design files from the Gadget Factory project page.

This project started in the comments on a post. Initial circuit design, PCB layout, development, and testing continued in the forum under the code name Project SUMP PUMP. Many, many people contributed ideas and advice, the Gadget Factory and Dangerous Prototypes coordinated circuit development and routed the PCB. We borrowed heavily from the Gadget Factory’s Butterfly Platform.

The Open Logic Sniffer is a purpose-built logic analyzer board designed to be low cost but high speed. It sacrifices a lot of the features you’d look for in a full-scale development board to achieve our primary goals:

70MHz+ sample speeds
32 channels
16 buffered, 5volt tolerant channels
USB interface, USB powered
USB upgradable everything
Make it as DIY as possible
Make it as open source as possible

We didn’t quite hit our initial price range, but we got really close.

You can get your own assembled Open Logic Sniffer at Seeed Studio for $45, including worldwide shipping. Continue reading about the design and collaboration below.

mark一下,比较比较.个人不太喜欢PIC系列MCU.

STM32_Study 发表于 2010-4-17 13:22:33

关键还是在上位机

如果能破解孕龙或ZLG的通讯协议，直接给数据给上位机，那就有意思了

没外部RAM，储存深度很成问题。

同意，没有深度就没有用处

哈哈，真是EAGLE。

asp88 发表于 2010-4-18 10:39:51

国外基本开源的电路图都是EAGLE啦

前段时间要调试stm32，就开板子做了一个。效果还不错的，有兴趣的来看看。
