So let me get this straight do you use yagarto with eclipse for the IDE? I've been doing a little bit of reading around line whenever I have the time. Yes, Eclipse is the IDE (with all that baggage, java, etc) Yagarto is the Compiler/Library set. Maybe I didn't say clearly, but I tried Yagarto/Ecli...

Winarm is good. I like it tons better than Eclipse.

WinArm uses the gcc toolchain, if you are familiar with this it helps.
Openocd can be fun to setup. So far the only tough spot was changing the
startup.s for my HW a futurlec 2103 board.

xbee breakout mods

 by motopic ¦  Thu Apr 09, 2009 1:40 pm ¦  Forum: New Product Ideas ¦  Topic: xbee breakout mods ¦  Replies: 0 ¦  Views: 657

Hi guys, I suggest this because I need it and will have to make my own probably. I need to mod the xbee breakout like so: Add a 4 pin .1" SIP: +5v:Gnd:Rx:Tx Add a resistor (i am using 10k) to Rx line (for 5v signals input)(guss this should be optional) Add optional diodes to drop from 5v to 4.2v (or...

Hi, I recommend either starting with either Futurlec 2103 or 2348 dev boards. I have both and they work fine. However, Futurlec uses different crystal freqs so be prepared to change the boot files. Be prepared to wait 4 weeks for delivery, Futurlec can take a while. Download WinARM for these. I also...

Gnu. Yagarto and Gnu Arm. Gcc is VERY reliable, I have used it crossplatform for arms and ppcs with no issues. I haven't looked but I bet Rowley does not support Futurlec boards, which are 1/2 the price of Olimex. Granted I have not yet had time to test them thoroughly, but initial serial port tests...

I too am very intereted in this project. I have a 2148 and sd-card interface that I could use. I will try to get the Spectec, could the originator post a supplier in the US? Also a consideration is unit cost and availability. I found this one on compgeeks.com, and google turned up a reseller (Everte...

You're in luck. http://www.sparkfun.com/commerce/categories.php?cPath=2_109 Actually, its nice device for learning. I think its a bit expensive for a product. They are very helpful on their forum and constantly work on the code compiler and such. Bad news is the new device has no io, you have to buy...

Have you tried doing a static build (in your jail) for this app?

I dislike Eclipse, and also want to build all the arm7 tools for integration in Emacs.

Hi, I am just a little ahead of you. First off is choices, choices, choices. Tools, libs, hardware...the list is long. Next is compilers like Yagarto, Winarm, etc. Most are GCC based. I am not convinced that the ones offered for sale provide anything more. But you can sure spend a lot of money on th...

I just posted this question to the LPC2000 yahoo forum yesterday. Apparently there is NO central newbie/get started area for arm7. A shame really, it should as simple as opening a wiki. Maybe I should do this? Yes, I get a bit peeved when vendors want to charge me $1500+ US Dollars for a GNU toolcha...

Just replace the MB. Do more research, are you sure the PW is not held in a eeprom? I had this issue on a old laptop where the pw was held in a 256byte serial eeprom. Just airwired a flyover to a eeprom programmer and dumped the contents. Toshibas usually have a reset dongle. Used to just wire up a ...

Coridium armmite daughter card

I like to use the Coridium Armmite arm7 dev card. But I spend a lot of time building up a breakout board on perfboard. A dev card that sat on top of the Coridium card, that ran out 5v, 3,3v, gnd and the io pins would be great. If I get it done first I will post here, otherwise the challenge is to yo...
