    TI LaunchPad

    I ordered some chips from the estore on Wednesday (for about $10), and there was no shipping (at least to Germany). Should arrive today...

    CCS for $9.99

    And I just received the online activation for CCS It even already appears in my TI account so I don't need to enter id...

    CCS for $9.99

    I just ordered. The store added two additional line items (for the LP and the CCS) to the shopping cart, but the total amount was still 16.98. It seems as if the promo item is just a bundle.
  5. Switching MISO and MOSI for a SPI EEPROM, while building my PicKit3 clone. On the original schematic from the PK3 user guide they are called SDI and SDO, for both the MCU and the EEPROM. So I naturally connected SDI to the same net, and SDO to another one. But in reality SDI was the input on both sides, and SDO the output - so they should have breen swapped. It took me about 3 months to find this out
  6. Yes, I did (and its still my preferred prototyping platform). But first I should add that its perfectly possible to use Keil, IAR or Eclipse for the software development part, so you are not bound to the editor of PSoC Creator. Linux support is still bad, though (I use a VM with XP in it) My first project, several years ago, was a combined analog-digital scope. 2 analog channels, 8 digital inputs, 1MSpS, up to 48kbyte storage (so 16 samples for everything). Digital triggers where based on bit-state with masks. Analog triggers where with configurable trigger level and slope and edge direction, and they could be combined with the digital triggers. Analog channels also had a PGA with up to 50x gain. Best of all: this was still only a single PSoC5, and its done in hardware completely (so the software just needed to set up the parameters and wait for the result). For the UI I used a GLCD and CapSense-buttons. (I even did a video on it, showing how it works and build) The biggest change in development with PSoC is to think more in hardware than in software. Many problems can be solved much easier and effective when using some of the hardware blocks (or by programming one of the UDBs). Another project I did is a reciprocal frequency counter. That one is also done completely in hardware, somethings that also not possible with other MCUs (one needs not only two independent counters, but also some small amount of logic between them)

    CC3200 Wifi delay issue

    The SSL demo project for the CC3200 explitely says that a connection cannot be up-graded to use SSL (nor can it be down-graded). It also mentions this as a limitation of the CC3200.

    Thermocouple BoosterPack ADS1118

    The ADS1118 has an built-in temperature sensor. Look at the documentation of the booster pack (http://www.ti.com/tool/430boost-ads1118), there you find the schematic. Apart from some passives, ESD protection and the LCD there is nothing else on the board...
  9. The question about the distance of sensing made it into TI''s LDC1000 FAQs: http://e2e.ti.com/blogs_/b/analogwire/archive/2013/10/11/inductive-sensing-top-three-ldc1000-questions.aspx?hootPostID=82de5e49190b64ee7efb9439a28c60e3
  10. If you see noise or interference, you can try to increase the "response time" setting (or reduce the data rate). As far as I understand it, the former should increase the oversampling (though its not really explained in the data sheet). According to the data sheet, the lowest frequency is 5kHz, so it should be possible to set this in the GUI to about 20% below the resonant frequency you measured (about 22kHz).
  11. I got some feedback from TI about my article. One of their product experts told me that, for a more general metal detector, one either needs a larger coil or should add a ferrite backing to it. So I did some more experiments, though not with a larger coil (so the results are not as good as they should be). I need to go into the coil winding business...
  12. Yes, I used the supplied PCB coil only. But I also looked at the WEBENCH tool for the LDC1000. When you try to calculate coils to detect 1cm copper object, you get at most a distance of about 6cm (though the tool only goes up to 7cm distance).
  13. The data sheets states "1.7mA" plus the LC tank current. So it seems to be OK when its not always on.
  14. I had first go on the EVM (it arrived on tuesday): http://blog.hendriklipka.de/archives/2013/09/ldc1000_test.html This sensor is really sensitive (and accurate), but it is intended for small distances. So anybody thinking about using it as a metal detector will be disappointed.

    CCS 5.3 beta available

    A year or so ago I bought a EKS-LM3S8962 kit, which contains a board-locked version of CCSv4. is it possible to upgrade this license to CCSv5? Or does the free license run with this board in an unrestricted manner?
