Re: Advice on buying JTAG Debugger (Newbie)

Remember though that the discovery board may need connectors etc adding to support all the interfaces - this is why the actual board is low cost. So you will have to design or buy adapter boards, eg. Cheers Spen Also read the license carefully. No commer...

I have had good experiences with pcb work, and I have been meaning to ask them to quote me full assemblies but have not yet. So I dont really know.

IIRC its soft rubber type plastic.

Heat a metal object or use a soldering iron. Do NOT TOUCH the plastic, but use the radiant heat to melt the pins back and 'rivet' the treads together.

Practice on a small diameter piece of styrene to observe the effects...

Thanks also. I took a look at the first part briefly. Seems very detailed. Problem is you are headed to 'very detailed' for a 'very specific set of tools and addons'. The hw addon world is very fluid, this time in a year or 2, those devices may be unavailable. In my view, the hw and hookups are stra...

As they told me when they shut down my rocket plant and moved it to Utah, "Rockets are known domain now. Thiokol Mgmt c1991". So data acq for rockets is well known now. Reliability and oversampling are your keys, you only get one test (or maybe 3: 1 nominal, 1 hi temp, 1 lo temp). Also if it does go...

Re: Can SNMP be used with Arduino Wifly Shield

I'll try. Arduino comes with a default ethernet library. The ethernet library accesses the low level eth hardware to send and receive packets and other details. This library is written for the W5100 eth chip that came out about 8 years ago. Since that time other chips appeared, and people 'have' wri...

Joeisi, the answer is maybe, because the Agentuino code is built on the Adruino default Ethernet hw library. This lib runs on only 1 chip (or it did)(the 5100) and the SNMP part used hardwired functions from that lib. It was an early task I identified when I looked at it a year or more ago - to sepe...

right, smart users scan the "new posts", where it does not matter what section you post in, it shows up in the list.

most important is a clear title !

I don't think leon is upset with you 'personally' as he is a very helpful poster. But you just hit being the 100th person who asked a question that is easily answered in the docs or by doing a simple google search. Did you try 'eagle pcb add via' ??? btw, why/how do you get 16 layers in a 1mm board?

Not sure why people fixate on Linux, but why not look at this. (linux is extremely 'fat' for micro-type SoC designs) cortex m3 arm stamp module: and ELua: get the binary that already 'just works'.

Well compared to most here my experience is different. I didn't grok eagle, I dislike products that limit me. So I went in search of Free, Open Source tools. I ended up learning TinyCad and FreePcb. I also don't proto with shields either. I breadboard using a RBBB and breakout boards (like SF breako...
