  1. that is a kind offer, but I am looking for/designing a mount for the flex module from LS Research, or similairily the MChip module. Have a look at the deals section, you may want to get yourself a demo of the flex for the price of shipping. KB
  2. has anyone seen PCB's that will acomodate the transceivers? I would work on one, but i am not sure how to import the footprint library from the eagle files.
  3. the reason for the 553 was the RAM size, i think i mentioned the TCP/IP stack is 12KB
  4. very well done production. he was using python and arduino and he mentioned a web socket and telnet connection. Very smooth operation but i couldnt find his code :cry: I saw a couple dudes at Cornell that used the msp and ezrf2500. http://jeremyblum.com/2011/05/14/msp430-wireless-weather-station/ it looks like TI has some good software which works. They programmed their GUI in "Processing", http://processing.org/ and are sharing all of it. I am still pondering schematics here.....
  5. thanks for the support Hylian. I did not want to confuse anyone on your post with the Microchip radio idea. As far as i can tell from your link above, this code will work well with the LS Research and other TI based modules, using 3-wire SBW ie: but apparently poses a challenge with 4-wire setup in the LS Flex module as well as the Microchip version: (note the SBW pins) I cant find any TI four-wire SBW software examples
  6. Hi All, I thought I would share an issue I have with my stubborn nature. Before I came across the LP Research transceivers, which use TI components. I purchased a Microchip model with the hopes of making a 802.11 node for the LP. I got the thing mounted, and proceeded to go through the schematics. I found a hell of a time using 4-wire SPW, and recently found is only possible to employ the G2553 within the value line. I even considered using the on-board F16, but there do not appear to be appropriate pin availabilities. The second issue was finding some examples to work with. As far as
  7. I would have shared the info sooner, but i was just as skeptical......
  8. my confirmation from a Sat order did not come until Mon AM. It is legit, and too good to be true, but they came on Thurs AM, and all is well. Trying to figure the best way to mount them w/o a custom PCB was the first challenge. this other device cost about $30 and had fewer pins, but is resisting communication with the LP SBW, but i haven't quit yet! Using a FR4 PCB, with SMT connections (gave me pads at 1.27mm), I cut the board down the middle to accommodate the wingspan. I was able to get it to complain via uart to terminal connection on CCS, " Current Boot is ROM.
  9. be cool, order yourself the tool and help us get it goin'
  10. I came across these promotional items the other day: http://components.arrow.com/part/detail ... 91464N1044 Try not to be to greedy, and shipping isnt so cheap! they are difficult to work with, ie the 1/2 pin pads are spaced at 1.27mm Have some fun and please share your successes! KB
  11. Hey Rob, please help me find funct.asm
  12. did you guys see this one? http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... K:MEWNX:IT hell of a deal, but no push switch
  13. you guys never fail to blow my mind. Two incredible ways to attack this problem, cant wait till i get a moment to put them to work. Thanks. KB
  14. Hey Zeke, as I grope through this new sensor, I am able to get your code to work for me. A little bounce, which i can deal with later. What do you think about porting the LED bits to the HD44780. How hard is it to estimate 8 positions and TX that output to the RX of the same chip to have a graphic output on the LCD? Edit: sorry Rob, I did not see your post. What about using a larger chip such as the 453 or 553 for more pins? the uart project from a couple weeks ago only uses 1 port KB
  15. Sorry to bother again Rob, How difficult would it be to have your code work with the HD44780, forgoing the serial board for simplicity, and having a contained LP sensor/display shield? Thanks. KB -Always thinking, sometimes clearly
  16. Hi Rob, In trying to understand the code in the encoder discussion, I am here. What kind of display is that. It looks like you hooked it up directly to the LP? thanks. Ken
  17. Hey RobG, can you elaborate a bit on the LCD? where can i find that include, and how are you wiring it up please. thanks
  18. Hi All, have any of you peeps tried to hook up a rotary encoder to the LP? I picked up a few cheap ones with the intent of using them to make a wind direction indicator. Thinking analogically I figured I could work with the msp430, and use them similar to a potentiometer or joystick. I would use the resistance "zones" with the LP using the ADC or comparitor. I dissected one of the encoders, and removed the spring so it would rotate more freely. Hoping it still would allow the contacts to function, and noticed the contacts were staggered copper pads. This jogged my memory, remindi

    Stormy Nights

    Normally Illinois skates by the season extremes of the summer, but this year left many of us without power. I was caught with my pants down, but lots of spare parts on hand. After the despair of the food going to rot, and the sun setting, the air free from the sounds of compressors, we broke out the candles. Moments later the reality of a night without the computer, and my need for more input, I decided I needed to open a real live book. The candlelight wasn't cutting it and by the 1.0 lux light source, I fashioned the torch from some leds and battery packs i had laying there. The kids wer
  21. Not a bad option at about $21 http://cgi.ebay.com/2-4GHz-RF-Transceiv ... 19be6f3764
  22. I dug thoroughly into your post.txt today with the intention of helping you out with a simple schematic. I obtained sparc's version and way immediately surprised that it was identical to other proprietary versions i have tried. Immediately I found that common chips are not available in the library, and that even simple jumpers pose some difficulty. I was willing to label them. I found a TI 14 pin msp chip which resembled your design, but could not obtain a simple 16pin header to wire the connections. I found one I thought would work and then it would not let me route connections. what
  23. It is working for me. Had to learn about VS, and that wasn't so bad after CCS Neat project. Hopefully this will help make a nice remote monitor for a LP solar energy project. Much thanks for the tutorial post. Hope I can add something later!
