  1. All, after months and months of not being able to get even one RS485 device working, despite it working before then suddenly stopping, I have finally been able to make it work again. It was not my wiring, circuits, chips or in fact any of the hardware at all that was causing the problem. Vlad333 on another post indicated recently that his stuff stopped working too, and that updating the Arduino IDE programmer (which forms part of the Arduino IDE program suit) resolved his problems. Today, using the same hardware that had refused to work, I simply updated the Arduino IDE, reflashed the Ar
  2. Vlad333, you have finally unlocked the mystery of why I could not get RS485 working! I got round to trying it today, by upgrading the Arduino IDE program suite, then set up one of the RS485 enabled stepper boards just the same way as I had what feels like a million times before. It worked first time, fuss free. Thank you for that lead, you have unstuck something that had literally been non functioning for a year. Cheers Les
  3. Hi there, can anyone advise if there is any way to increase the rate of transmission of data, or at least measure and log it for the purposes of outputting information to arduinos for use with stepper motors? As described in another thread, I have narrowed down some very poor quality of stepper motor movement for gauges to either the data rate refresh from the DCS BIOS output, or how frequently the Arduinos are processing that data to send to the stepper motor. Cheers Les
  4. Following on from this, I did a test yesterday using four X27-0168 steppers, each driven by an Arduino Nano via (respectively) an EasyDriver board, an A4988 driver board, the AX1201728SG driver and finally directly driven by the Nano. All were set with the DCS BIOS sketch for the APU temperature so that I could see how they performed with the different drivers at the same time. The result showed them all acting almost exactly alike, crucially including the jitters. At low pointer speed, they all virtually simultaneously stepped from one position to another, stopped together then stepped again.
  5. Well, I will give it a go - I have lost many fruitless hours to RS485 in the past, so a couple more won't hurt! Thanks for the lead on this, fingers crossed! Les

  7. That's interesting - I had RS485 working at the beginning and then it stopped working one day, and defied all attempts to resurrect it. I assume that you just update the Adruino IDE program? Cheers Les
  8. All, in pursuit of some improved behaviour of things like gauge movement, OLED displays etc, I have found myself wanting to actually see a logged record of what is being output by DCS bios and when. To take the output for a gauge as an example, what I would like to do is see what signal say for the APU temperature is and how often the signal is refreshed Is there any way to do so? Cheers Les
  9. Hi Vlad, are you saying that updating the Arduino bootloader will help with the RS485 not working Cheers Les
  10. I have finally got the AX1201728SG chips working. A batch of five of them were bought from a German supplier, after the first couple of attempts using Ebay sourced items got nowhere. Once soldered to the SOP/SSOP to DIP Adapter boards I had previously bought, I was able to fire up the stepper with some test sketches. However once I put in the DCS bios sketch (a test one using MiddleFart's sketch as a basis) while it would work in the game, it did not change the quality of movement measurably by eye. Now, I know this is early stages yet, as I haven't tried to play around with the settings in
  11. I used the commercially available SOP/SSOP to DIP Adapter boards for this, which worked well with other SMD chips, but whether it's a combination of poor soldering techniques (I have no access to a reflow oven) or poor quality chips (I have no way of testing them prior to fitting to the boards) is not clear. I have some new chips coming from a seller in Germany, so will have another go with those when they arrive **** EDIT **** As it happens they must have arrived yesterday, they were in the post box this morning. I mounted one of the chips on the adapter board, and I'm pleased to say
  12. Thanks - I presume that the drivers were soldered to a breakout board, which I have tried without success to do. However your feedback does encourage me to keep trying, as it sounds like it is a good potential solution. Any tips on getting them to work? I was pretty careful to attach them to (purchased) surface mount adapter boards, but must have done something wrong! Do you have pictures of the PCB so that I can see if it the same type I have tried? Cheers Les
  13. I think we'd all be interested in seeing what the driver you use with the X27's is, as I know that I am not alone in seeing jittery movement with them Cheers Les
  14. You are having the same dissatisfaction as I have with the pointer movement on home made gauges - take a look at this link https://forums.eagle.ru/forum/english/dcs-world-topics/input-and-output/home-cockpits/278624-experiments-with-stepper-motor-drivers-for-gauges?t=276220 for some messing around I did. I am still trying to get the AX1201728SG stepper driver board to work as anecdotally it makes the movement smoother, and once I have any feedback (positive or negative) I will be putting it on here. Can you clarify whether the steppers you are using are the X27-168 type? Cheers Les
  15. Maybe for you! I can't get it working after 18 months of trying unfortunately Les
