  1. @borg not me, I did not even realise that popup dialog existed.
  2. @LulaNord that would also make sense if the MAC addresses are the same and they are connected to the same network switch. The routing table in the network switch would not know how to handle the traffic. https://serverfault.com/a/462190
  3. @GoranP, I am glad to hear I was not the only one with this problem, I immediately assumed it was something I was doing wrong with my code... @borg I don't know when you generated the images on your website, but the automated configuration process might have been having issues longer than you think. The MAC address for the screenshot on https://www.tinkerforge.com/en/doc/Hardware/Master_Extensions/Ethernet_Extension.html#ethernet-configuration has the same 02:A0:00 ending.
  4. I only have two accessible at the moment, and they both had the same address 40:D8:55:02:A0:00 which does not match either of the stickers.
  5. I did not realise I had to manually set the MAC address on each Ethernet Extension based on the sticker under the Ethernet socker. Now that the MAC addresses have been set, TEST 4 works perfectly with a 0.05s average time to connect.
  6. This is a fairly critical issue for us as our project requires at least two Ethernet Extensions in it's current configuration, so any suggestions would be greatly appreciated. Have a good Easter break
  7. I have been having a lot of problems getting the Ethernet Extensions to work reliable when used together. My test configuration consists of 3 master bricks, 2 Ethernet Extensions, 1 Raspberry Pi running brickd and a Windows PC running C#. The Windows PC is running the latest C# bindings and code very much from the Rugged Approach tutorial (full code at end). TEST 1: Connecting to any IPConnection individually (by commenting out the Connect command for the other two) works very reliably and takes consistently about 0.05s. TEST 2: Connecting to the Raspberry Pi and any one Ethernet Extensi
  8. The shopping cart does not seem to fill screen width when used on a mobile device. I have attached an imaged generated using Google Chrome Device Mode. https://www.tinkerforge.com/en/shop/checkout/cart/
  9. Further to this I have just tried to compile tag csharp-2.1.10 which does not include the json files and works perfectly, it is only in 2.1.11 and 2.1.12 where I have the compile problems.
  10. I am attempting to compile the C# bindings in a Ubuntu 16.0 environment using mono compiler version Stable 4.8.0.495/e4a3cf3. Reverting to csharp-2.1.12 git tag and running the following commands: cd ~/tf/generators/csharp python generate_csharp_bindings.py && python generate_csharp_zip.py I receive the following xbuild compile errors: Project "/tmp/generator/csharp/source/Tinkerforge/Tinkerforge.csproj" (default target(s)): Target PrepareForBuild: Configuration: Release Platform: AnyCPU Created directory "bin/Release/" Created directory "obj/Release/" Target ResolveNuGetP
  11. Ah yes, sorry, I meant to say R8 and R10 in my last post and should have multiplied the resistor by 6 rather than divide. If I change both R8 and R10 to be 33k (e.g. http://uk.farnell.com/1717610) and leave R13 and R14 at 280k, I should be able to get a range of +-5.09V (at the input to the U1B) to provide the required 0.6V the ADC0 net. Will I then need to recalibrate U4? to convert the reading would it be as simple as dividing the result from the API by 7.021 (based on 35.745/5.091)?
  12. Thanks for the speedy reply! I am measuring a 0-5V signal, where ideally I would like to achieve an accuracy of +-1mV. If I could get the range down to a 6th of current, that would give +-5.83V range which assuming the accuracy would be also be 6 times improved would work for our application. Would it be as simple as exchanging R8 and R10 to 4k7/6 resistor? Going for something readily available, like a 787 ohm (e.g. http://uk.farnell.com/1752470)? Edit: Resistor labels changed to read R8 and R10
  13. I seem to be getting confused by the resolution/accuracy quoted. The Industrial Dual Analog In Bricklet quotes a resolution of 24bit, which on the 70VDC full scale would give (70/2^24) roughly 4 micro volts resolution. The accuracy is quoted as 4mV. Is the resolution really 1000 times better than the accuracy?
  14. I don't understand the technical specifications given for the Analog In V2.0 Bricklet 2.0. It gives a voltage range of 0-42 VDC at 1mV step, but a 12bit resolution at 10mV step. How can I achieve the 1mV resolution? As I cannot see any software adjustable resistors (as with the V1.0 bricklet) I don't understand how I can achieve any better resolution than the 42.9/2^12 = 10.5mV.
