  1. Ran into an issue like the one above when attempting to use a G2452/usi spi. I was getting an isr trap which turned out to be an unhandled isr for the usi spi comms. I reported this to Spirilis. An update is forthcoming that resolves the issue.
  2. I've been thinking of designing a board as well for use with the nrf24l's since seeing Spiriliis post and code. Something similar in size and compact similar to yours. Wondered if you had looked at different crystal options. Just wondering as I was able to source some smaller rectangular ones and mounted them closer to the xtal pins which saved a lot of space compared to the barrel type. I also opted to use the internal caps vs the external option to save space(and soldering headaches that could be involved). Had you looked into using lipo cells? I've been using a small setup that allows for u
  3. I was able to get this(the upload part) to work (mostly so far) by using a 5v version of the ft232R cable(LED/res used to drop the TX line). The transfer was successful but not able to detect the device on my windows machine afterwards. It does appear to be detected on the linux box I have though. As a side, soldering the pin22 and 13 is like doing surgery.....you need a very steady hand. Question related to tp2/4, do these need to be disconnected from the buttons once this process is complete for the board to be connected again? Edit: So after a few minutes of being disconnected, I t
  4. From looking at the errata from both the 2231 and te 2452, they both suffer from the USI bug related to sending data 1 additional clock, though I haven't checked teh 2553 for any strange behavior. The issue with the addition clock tick handled in the code already though...so.... Edit: I tried various workarounds with the clock tick bug but none worked. I would imagine that the issue would persists with the clock phase being set to a different mode, but I could be wrong.
  5. These are the ones I have. I'm pretty much using the code from your post on the nokia 5110 with minimal changes. It seems odd that this works with the 2553 and not the 2231/2452..... #define LCD5110_SET_COMMAND P1OUT &= ~LCD5110_DC_PIN #define LCD5110_SET_DATA P1OUT |= LCD5110_DC_PIN
  6. so....USICKPH was the issue? As a side, this is one of the settings I hadn't tried to change but after going over your code, this was the only thing that I had to comment out to get it to work. Thanks Rob, I'm surprised others hadn't run into this before..... EDIT: curious why using the CKPH =1 works on the USCI with the 2553 but not on the 2231. Any thoughts?
  7. I've seen various posts with people running these, some with sw solutions, but I'd really like to use the hw. The issue is that I just get the blank screen staring at me when using the noted chips. When using the 2553 and code sample from RobG's post, the display works fine(without hw reset). when attempting to run on the other chips, I get nothing. I've got both wired up identically(per diagram in RobG's post) and tried the code sample that was posted in relation to the 2231 later on in that thread. I've tried various changes to the code, adding hw reset, changing the order of hw config set
  8. Nice setup. Did you use the pins for the 32Khz crystal for anything or have any plans to? Had you considered a 5v switching regulator for the display(I had similar issues with the display not showing up very well on lower voltages). I think the transistor idea for the LCD panel enable/disable would be useful. If you don't use the pins for the crystal, you could also use those pins for for button actions(start/stop) or other things.

    Water Pump

    I've had a similar project on my bench for a little while. For the water pump I picked up a small pump on amazon that runs off off +5v power supply(was trying to find something that was based on those little solar water pond things but not the submersible type) I think it was around $10-20ish (though I can't find it again). It's not very powerful(3-5lpm), but I've run it off of a solar panel and have managed to have it pump out of a 1 gallon water bottle and onto a plant about 2-3 feet up. Hose size was fairly small, I'll have to check it later. 2 issues that I'd so far ran into. This was not
  10. Just wanted to say I've been a big fan of your blog and have visited it often. Always happy to see new content there and doing stuff with the newer chips would be great. I still like using my 2211/2231 chips for things so I don't mind seeing any content for those as well. I try to check a couple times a month to see if there is anything new. Thanks again for a great site.
  11. @@ToF Yes, I actually plan to dust it off and get things going on it again. It's amazing how time flys!
  12. I'll take 2 of each as well voodoofish ----- 2 modules ----- 2 boards
  13. Very cool project. Question for ya on the msp430 jeenode code. Was this tricky to set up and do you have any suggestions on using them? I've got a pair of rfm12b's as well and have been considering trying them out sometime. Just want to know what sort of issues you ran into (if any) while playing with them.
  14. This is the first graph of data pulled from the data logger. This was a simple test, but verified saving and retrieving of data from the chip and some other test functions that I have been working on. This test used the WDT interval timer and took roughly an hour to run to collect 4096 samples. The variances in temp were due to the time and the amount of sun hitting the logger(2 rapid increases in temp). I think it's time to populate another board as I know the setup works and would allow me to start running longer tests while working on code.
  15. Thanks BH! As promised, the code....though it's far from finished, it does work...mostly.... :/ I know a lot can be done better and don't even bother giving me grief on the blinky code....it's an embarrassment, but hey, I know it's bad and I'll fix it!!!! :shh: Don't be too harsh...it's work in progress, I'll be updating it more tomorrow and possibly tonight. DataRecorder2353Test_v.02.zip Edit 1: updated code to V.02. This has a lot of fixes improvements and tweaks. Improved blink code, added INT handlers for several areas, added test code that works. This has test code in the
  16. The first addon board came in and with a little bit of fiddling, filing and fitting, I was able to get it attached in a way that would work. The header post length was a bit longer than expected so I had to place the male headers through the underside first....not the best way to set things up, but we'll figure out what I can do. Still working on coding the mem chip which I'll be posting the current code for in a short while. Once getting the code sorted out with the mem chip I'll start to work on the code for the temp sensor to do some logging of data.
  17. Update so far. After a frustrating day of not seeing any viable response from the eeprom I tried my luck on IRC to see if anyone had any ideas. Lucky for me Rickta suggested that I try a configuration that worked(it was my next step, Honest!!!). Seeing as I had some 2553 chips and the original mem chip that I used was a dip version that was similar to the new SMT chip, I figured I'd try to do a read of memory that I knew had data on it...with a bit of updating and testing of my write function, I was able to at least get a simple test program that would write and read the memory address. Switch
  18. I received the datalogger board today and after multiple hw tests to verify that board functioned as expected, I completed the first of 3 test boards. The last test is to verify that the memory chip is recording correctly, and until then I can't say that this board is 100% functional. though the current 80% has me pretty excited. Now I'm waiting for the addon board that is breaks out the datalogging pins plus a couple other pins to a usable 3 pin configuration. Images included in this set have the button 1 switch which allows for it to be a reset or action button, and the male header pins.
  19. Yep, I was talking to Rickta on IRC about it as well as finding the petiteFS post on the forum seemed to be a possible solution.
  20. @bluehash, I may go with them after I've successfully confirmed that the board functions as expected, though until then, I'm going with smaller batches through dorkbotpdx. I will hopefully have the boards by early next week and start the build/testing of each. @krzyk2 Hadn't thought about that, but I could actually add it to the bottom of the board or make an addon module to allow for it. I'll have to look around and see if there is a simple fat/fat32 file system lib for the 430. I'm pretty sure I"ve seen one on this forum.... The addon board that I did design has the UART broken out as to
  21. Renders of the boards and how they should look when completed I worked on this last night, this is the addon board with support for plugging in adc devices plus a simple light sensor onboard for simple testing. The light sensor circuit was setup incorrectly so this is not the final version, but pretty close. Rendered version of the main board.Can't wait to get it and try it out! :thumbup:
  22. Thanks RobG, that will most likely be saving me from hours of hair pulling.....
  23. Data Logger module. Renamed from data recorder since it just didn't sound correct. I worked on this over the weekend as I was looking to create something simple for a(the main)project I've been working on. I was thinking it would be something similar in features(though a little more) to the uLogger that SF sells in that it stores readings to a mem chip and was small. I could see this being useful for some projects. I was hoping to get a once over(feedback) on it to see if anything overtly wrong could be spotted. As far as I can tell, everything looks good and it should work as expecte
  24. Do want! I think I may be in for one of these as well.
