  1. Sorry, didn't notice you said micro. With the ones that have only one port, the TX and RX part are what's important. The digital port pins are probably different because the Nano uses a 328 processor and the Pro micro uses a 32u4. It should be OK as long as you select the right board in the IDE.
  2. I've not tried myself, but it should work as long as only one slave device is connected.
  3. On the nano, there's only one port, so "TX1" and "RX0" are TX and RX, digital pins 1 and 0. On the Mega, there are multiple ports, so TX0 and RX0 are the main port. TX1 and RX1 are the second port and so on.
  4. Can you try it without the Max 487s? I.e. connect just one Nano direct to the Mega pins. TX on one to RX on the other. Plus common gnd. That should eliminate the RS485 bus as the problem.
  5. Maybe you're losing steps? It happens with CNC machines sometimes. What's your motor wiring like? If it's spaghetti, that might be part of the problem.
  6. The smaller ones may be enough for the individuals. Having said that, looking at the schematic, they're already built into the Arduinos, so extra ones may not help. So then maybe the glitching is a function of driving multiple motors from one device?
  7. Yup. Very likely power noise. The high frequency filtering works better if you have it on every device's 5V lines. If you have it on just the main supply, any local noise can still have an effect.
  8. Anyone got any idea why this is happening? It looks like the undercarriage is collapsing on takeoff (Taxi is OK), but I can't figure out why. Collision lines and shells are in place on all 3 wheels, and another puzzle is why the tail wheel is part-submerged.
  9. It REALLY annoys me how condescendingly arrogant some of the people on the "coding" forums are. Stepper drivers wouldn't stop you having power noise problems. They might even make it worse. And reading a bit more, 0.1uF across the supply might help with the noise as well as 10uF. The 10uF gets the low frequency and the 0.1uF gets the high.
  10. Possibly. Might be noisy power lines caused by the inductive coils of the motors, too
  11. Putting it in the setup routine should make it run only once on startup. If you're having other power issues, could you be having a "brownout" - a glitch that causes the processor to restart? Maybe a 10uF or more capacitor on the 5V lines might help.
  12. Yeah. I think there's a configuration program on the Leo Bodnar page you can use to change the name. Look for "Renaming firmware" under "Product downloads".
  13. You should be able to click on something where the errors show up.
  14. IIRC, you have to use TX0 and RX0 on the slave devices.
  15. Maybe the RS485 uses a slower data rate? OR it uses a different connection protocol the Arduino has to "pay more attention to" because it's not handed off to a dedicated interface chip. When you think about it, the USB interface device handles whether or not the data is for the device, then passes it on if it is. With the RS485 setup, I assume the main processor has to decide if it should do anything with the data it receives
  16. It's where you select the aircraft module.
  17. If you use RS485, that goes in D0 and D1 too. They're the processor's serial lines.
  18. Not a good idea to use D0 and D1 if you plan to program the board with the circuit connected or use USB. The USB interface is connected to D0 and D1, so you can't use them with serial comms such as DCS-BIOS active.
  19. I found with the P51 that the gauge in the game uses a lookup table to make it non-linear to match the real one The solution is doing the same, with some interpolation maths, or redraw the gauge scale so that it's linear. The absolute speed numbers are available from the "common data" section.
  20. I suppose one option would be to try using an Arduino Pro Micro or Leonardo in the box.
  21. Thanks. I might try it. I run a gaming laptop...
  22. This one uses a matrix for 32+4 buttons +8 analogue. You just add diodes and switches: http://www.leobodnar.com/shop/index.php?main_page=product_info&cPath=94&products_id=204&zenid=ec67a171c1c110d61bf6b89e1c5d0910
  23. Maybe check out The Warthog Project. I think most, if not all of his inputs go via Bodnar boards. https://thewarthogproject.com/
  24. Are there memory issues with USB converters like these?
  25. Maybe ask the mod makers if they have a livery template like the official aircraft ones?
