  1. @@spirilis Wow, how exciting it is that you decided to resurrect this thread. I had a quick look at your links. So along with TI LVD driver chip, and the PHY you linked, is it essentially routing the control and signaling to some GPIOs on a launchpad MCU? And with that, you'd be able to drive the SFP?
  2. Thanks porting the library! I've got some of those BlueFruits that I use with Arduino. I'll give it a try on a few Launchpads and Energia.
  3. Ah, thanks...makes sense to me now. I had envisioned the MSP430 being on the booster pack.
  4. Thanks the heads-up! It's interesting, at the following sheet, http://www.ti.com/lit/ml/sprt630/sprt630.pdf It says it includes the MSP430G2553IN20 uc and the photo shows the G2 launchpad, but then goes on to say the MSP430 launchpad is not included, and the uc will replace the MSP430 on the launchpad. I guess the launchpad is necessary just for programming? I'm going to pick up a couple. (edit, there's a limit of one). Thanks again. Sterny
  5. I've only used the S2 parts, but think the S1 used the AT firmware - if it was a S2, I'd suggest making sure you have the appropriate firmware installed. Are you using the sparkfun explorers to connect to your PC? Can you a use a serial terminal program like putty/screen and get the two chatting by connecting a terminal to comX and another instance to comY, where x and y are the comports of the FTDI on the sparkfun? I'm not clear what you mean when you say you can see failing show up on the comport - do you mean the MSPs com/serial port? I've only played with xbee's on Arduino, bu
  6. Hi all, Thanks for all your support. I've been working on building a 'Nibbler' 4-bit CPU project by Steve Chamberlin ( http://www.bigmessowires.com/nibbler/ ), with the help of a board developed by William Buchholz ( https://www.tindie.com/products/wmbuchholz/nibbler-4-bit-homebrew-cpu-pcb/ ) The project provides some bins that include the microcode for the project that is intended to be loaded on a few Microchip flash parts, SST39SF010A ( http://ww1.microchip.com/downloads/en/DeviceDoc/25022B.pdf ). I was wondering if anyone could provide some tips or hints to use a 430 lau
  7. Does the AWS facility also support C3100 launch pads, or is the CC3200 required?
  8. Hi @@zeke, Wow, I think it would be fantastic if considered starting up your project. The fact that you have already implemented similar tech previously makes me think this could actually come to fruition. I don't have any experience working with designing boards. I do understand there are some board house services where you can submit designs and get relatively fast and quality service at a pretty low price (e.g dirtypcbs.com, et al,). But I'm a quite a ways off in my learning to even approach something at the complexity you mention. Learning the software tools (Eagle, etc) is def
  9. @@spirilis, Heh - yeah, SFP Boosterpack's - for when you need to talk to a MCU 300 meters away! I guess though, maybe one practical application would be a SFP tester, or maybe even a cable tester. But of course there are many products already out there that do that. For me though, it's the journey I'm interested in, and as this technology is related to what I do for living, dipping my toe in a bit deeper couldn't hurt. Plus, this type of media is where everything is at when it comes to device to device connectivity. Copper throughput and distance limitations are pretty prohibi
  10. @@zeke, Thank you again. I cannot express in a forum post how grateful and appreciative I am for you taking the time to point me in the right direction on how to begin my research on this project. Awesome!! @@spirilis, Wow, after reading a lot of your posts, I had always assumed you were a design engineer at your day job. Or, do you do storage admin work in addition to engineering there? I noticed that you've designed some boosterpack boards - based on the information @@zeke provided, how big of a lift would a SFP booster pack be? I'm just curious about some context from so
  11. HI @@zeke, Thank you very much for your reply. Your insight and suggestions are incredibly helpful to me. I'm actually familiar with 8B10B encoding and running disparities. Years ago, I attended some training from Medusa Labs, that provided instruction on fibre channel using Finisar's x-gig analyzers (whom was bought by JDSU a few years ago). Although at that time, I really had no previous exposure to the engineering side. And then recently, after getting into MCUs, and studying UARTs and RS232 signaling, I had an ah-ha moment. Probably apparent to most on this forum, but the
  12. I work in the storage industry, and my shop has a large amount of Fibre Channel and Gigabit Ethernet SFPs that are getting replaced and many are getting scrapped. I was working in the lab today and started wondering if any could be adapted in someway to get a couple MCU dev boards talking. I did manage to find a datasheet after some quick googling - http://www.avagotech.com/docs/AV02-0671EN So it's clear to me that at my particular stage in learning, interfacing with the board is beyond my capability. But as I continue my education, I think at some point I'd like to take a stab at it
  13. Hi Fmilburn, Thank you so VERY much for the link - this is exactly what I needed to know! I received a pm asking me for the coupon code to receive 80% off, bringing the 200 kit down to a more manageable $40. For everyone's benefit that is interested, here's the code I used: ENLABS It says while supplies last, and limits it to quantity 1. Regards, Sterny
  14. Hi bluehash, Thank you very much for your response. Also, thanks for the welcome. I've been lurking here for a few months after getting turned on to the launchpad kits. It's really made me a big fan of TI - the prices are great, and the documentation that TI provides seems to be first class as compared to the other ecosystems out there. I also appreciate that they still make alot of PDIP basic logic gates - really helpful for me as I get more and more knowledge under my belt. This is a great forum and blog BTW - I appreciate your posts about bargains out there So as it turns
  15. TI sent me an email announcing 80% off their TI-PLABS-AMP-EVM kit. http://www.ti.com/tool/ti-plabs-amp-evm I decided to pick one up as I thought it would be a good opportunity to follow their course and have something to experiment with. I have my own test equipment, so I'm not going to get National Instruments $2000 lab kit. Looking through the EVM user's guide (http://www.ti.com/lit/ug/sbou150a/sbou150a.pdf) I see that it has power connections that can be supplied by either the NI kit, or your own power supply. It shows using a 20v positive, and a 20v negative rail along with g
