  1. Glad it all worked out. Have fun with your UFC.
  2. wereferret, Good news. You have not wasted your money. Looking at the datasheet from the Mouser link above, the KB15SKW01-A switch is a single pole, dual throw, on/momentary on switch. This means one pin is normally on and turns off when the switch is depressed and the other pin is normally off and turns on when the switch is depressed. The momentary() means that the switch does not latch in the second position, but instead automatically returns to the first throw position. Again referencing the data sheet, I believe you want to connect one wire to pin 2, which is the common pin, and the
  3. And that's how you stop getting help, but I will try one last time. The pieces of a connector that actually make a connection are called pins and sockets, depending on which gender they are. It would be a bad idea to try to make the connection with only pins and sockets inside the extension because it would work loose over time. The pins do not have enough friction to hold. The metal and plastic piece that holds the pin/sockets is called the shell. This is the part that actually holds the connector in place. The larger plastic piece at the back of the shell is called, appropriately, t
  4. Really nice draken152. I especially appreciate the cable management effort you put in behind the panel.
  5. Does anyone know if there will be a separate entry in the control bindings for the RIO similar to the Game/Sim choices on some aircraft so we can have a specific control mapping when flying as RIO?
  6. What do you do first when the tomcat is available? I like to think of this as trying to park directly on the hanger deck by way of the transom
  7. Thanks Quick. This looks very useful for rapid testing of panels. I really appreciate it when folks share what they have done to help others.
  8. Exactly. The MAX 6956 and AS1130 are the Integrated Circuits (ICs) in the chain.
  9. Petardo, Thermal had the idea. A network attached USB hub. As I said in the earlier post, this is a slightly different approach to what you asked since I am not controlling any panels directly from the RPi. The Arduino is currently plugged directly into the RpPi, and you are correct there are only four USB portson each RPi. I plan to use multi-port USB hubs on the RPis as required to expand the number of Arduinos each RPi can support. Each Arduino requires its own instance of socat, so I have a shell script that instantiates them and is called at bootup. I have aliased the Arduino USB
  10. I have implemented an RPi with DCS-BIOS. I use the RPi to connect over Ethernet to the UDP listening socket of DCS-BIOS. I use socat on the RPi to pass the DCS-BIOS messages between the USB-attached Arduinos and the simulation computer. This is similar to what is implemented in the standard direct connection method of DCS-BIOS, except there is an RPi instead of a loopback. I decided to use the RPi because I hope to have a full simpit someday and I wanted to use Ethernet and RPis to distribute the data rather than either running several USB connections or using RS-485. It seemed simpler. Th
  11. Chewy, Can you be more explicit in what you are trying to accomplish? Do you want to wire up LEDs so they light up when a switch is thrown, as described on the BU0836X product page? If that is the case, you should be able to use the 5V supplied by the BU0836X board. You will need to look at the data sheet for the LEDs you are interested in and find the maximum current and the voltage drop in order to calculate the resistor required as Brewnix said. Subtract the voltage drop of the LED from 5V and then divide by the maximum current for the LED. That will give you the minimum resistance yo
  12. I forgot to say thank you for sharing your work in my earlier posts. Everybody's time is valuable and everyone brings different skills, so it really helps the community when we are able to cooperate. On the schematic, I appreciate the decision to include a separate BUS IN and BUS OUT. That should make daisy chaining easier and provide flexibility. I also like the addition of the power pass-through. It looks like you are using the decoupling capacitors correcting. The layout is a little hard to follow because the traces don't appear to follow a grid or maintain 45 and 90 degree angles. Is thi
  13. There is a capacitor connected between the power supply and Vcc pin on the MAX485 chip. This will prevent the DC voltage of the supply getting to the chip and so the chip will not have power. Often digital devices use a capacitor placed near the device and connected between ground and the input power supply to provide surge current as the logic switches. These are called decoupling caps, and I assumed that was what you were including in your design. I hope this clears up some confusion.
  14. I only took a quick look, but it appears Vcc for the MAX485 has a series cap instead of a decoupling cap between Vcc and Gnd on both boards. You should also include the recommended decoupling caps between Vcc and Gnd on the MAX7219 (10uF & 0.1uF) as described in the data sheet. I would include provision to add termination to the Rx and Tx lines of the MAX485 for the end points.
  15. I think you want to change the last line of your code to the following: lastFqisPin = fqisSelectValue; The way it is written now, it does not properly check if the new value is different from the previous because you are storing the address and comparing it against the New index.
