Awesome tutorial!!! I am happy that you’re happy with MobiFlight and that you’re actively supporting the community with your videos. Thank You!!! Many happy landings and good luck with your Sim.
Karl, I think it’s awesome that you are having Josh learn and help you. The quality of father son time is great, Im looking forward to completion of your sim and seeing Josh in the left seat flying a commercial airliner. I have a feeling there is a commercial pilot career in Josh’s future! Great job Josh, you are so fortunate to have a father like yours. It’s important to get good grades in school and plan for a four year degree. Thanks again Karl!
Great close up at the end of this video that shows you how to troubleshoot a faulty display by isolating the suspect. Programing displays also well explained and easy to follow. Thumbs up...
@@helimech8152 yes already started with your tutorials. Building a Pmdg 737 Ngx Mcp and landing gear lever maybe flaps arm later. But a question, sometimes a push button not work it works second time I press. On mobiflight website, there are some topics about this issue, it's a well known bug i think. Do you have any experience with your buttons/switches? Any idea about how to solve this issue? Thanks by the way. :) See u.
@@egecarsi yes, this problem used to drive me mad! I have actually mentioned this in my new upcoming video. You need to update to version 7.5.2 which should fix this bug! If you have an older version of mobiflight, you must enable debug mode in the settings under logging. It wont miss a switch then!
@@helimech8152 thanks a lot. You're right because I already tried that "debug mode" technique and it never missed. However my encoders started to slow down this time :) I`ll try to update my software. Thanks again :)
Haha, if you have mobi 7.5.2 then that is the downside at the moment. Switch off debug is this mode as the switch bug has been fixed. Leaving it in debug mode creates a really bad lag when operating normally now
First thing first, great job. I don't have prosim, is it possible to program the sim with only Mobiflight and FSUIPC? if yes, can you do small tutorial please?
Great video, I work with A320 but your video explained a lot of things to me. I would like to ask you: how many 8-digit LEDs modules can the current of Arduino Mega power supply before having to insert an auxiliary power supply. Thank you so much. Marco
Hello, That depends on how many are illuminated at the same time. I dont like to power more than 3 from the Arduino. I also have stopped daisy-chaining them to increase reliability. Kind Regards Karl
@@helimech8152 Thank you very much for your answer, in the FCU of the A320 all 4 lcdx 8 digits can also light up (they are not all number 8 of course). If a led absorbs about 20mA, multiplied by an average of 5 led x digit, 5led * 8 digit * 4lcd * 20mA = 3.200mA = 3.2A it seems a lot to me :((
Hi, best source of information from your youtube guide. I have a question on the green board 7 segment display. I know that there are 7 segment digits which are 0.28 mm and beyond. Are the green boards specific to certain sizes only? I intend to get hold of a 7 segment green board and 0.28 digits. Will they just fit or do i need to look out for something else? Cheers from Singapore
Hello Sim pilot, The 7 segments on the MAX7219 boards are 0.36". You might be able to bend the legs to fit into the sockets of the 0.36 with a 0.28" display. I have not tried, otherwise you will have to join them with wires and solder. Kind Regards Karl
Wow! You're amazing, thank you for sharing. I'm just going to start mine as soon as I get the parts. Do you have any idea if is that easy to program it on Xplane?
Wow, a lot of explaining. I hope I could follow most of it. You now need three pins to control the displays. But you will need a pin for every button and witch you have in there. Is thsi correct or is there also a daysi chain possibility in mobiflight?
Hi Mickey, The ground to every switch, LED can be daisy chained, but a dedicated line will be required to the Ardunio for each component. This is why the cable looms become very big, very quickly. i have not worked it out properly yet, but you need the full 52 lines on one Ardunio, and between 6-10 on an another Ardunio mega. Last time i used the second Ardunio for the EFIS panels, but hard wired them. This means i can longer remove the MCP with removing EFIS. Rubbish! I will need to correct that by fitting removable connectors for ease.
@@helimech8152 OK, that's why I'm planning to use the MCP23017 port expander with the arduino. It would be really great if they would implement this in mobiflight.
Hello Heli! You've inspired me to start back building a full simulator! I have a question for you. What is your main sim being used? and also what program and aircraft add-on are you using to program all components? Is ProSim its own aircraft add-on like the PMDG? Or do you use PMDG alongside with Prosim737? looking forward to your response.
Hello AviationTalk, I currently using P3D and Prosim's 737 flight model. This provides the correct flight dynamics, the visual is just the forward view without any instruments or windows. Perfect for sim building. I am also using MSFS2020, but strange things are currently happening when I try to run my sim through it. But as you know, the graphics are awesome. I also believe PMDG 737 and Prosim can run together as they interfere. PMDG was what I used to start with, then progressed onto Prosim when I knew I wanted to go full hog! Of course, MobiFlight is the middle man proving all the interface programming. Hope that helps, great to hear from you. Kind Regards & Good Luck Karl
@@helimech8152 Thanks for the response! Im going to be using your entire plans from your website, you are unbelievably talented. I have one question for you, are your plans 1:1 scale of the real 737?
Do I need prosim to use the mcp? My understanding is that prosim is awesome but out of my price range. I will try and connect through fsuipc7 and mobiflight.
These 7219 boards that you say you prefer. Do you have a link to those by any chance? Those ones appear to be a lot nicer than the ones that are pre-assembled
Hi. Just want to ask as i did the same connection and the digits are reading from right to left. I.e. sim says 125 display says 521. Any suggestion?thanks in advance.
Hello again, in honest truth when I started, It was all guess work! I started off with the smallest byte, then kept increasing until it worked. Now the correct answer is all to with the actual number size you end up with. Numbers uptown 255 for one byte, 36464 Something for two bytes, and you have to increase a byte if its a bigger number than that. I will explain better on the website later. It also depends if it is a minus number too.
@@helimech8152 Thanks. I have one more question regarding displays. Can I make a daisy chain on all 4 digits 7 segment displays, which are available on the market? Or I need to use these MAX7219 dedicated for Arduino? I want to have a different color (white or orange) however I’ve noticed that in my country MAX7219 is available with the red color only and soldered to the PCB… What should be the vertical height of the display to fit correctly in the front panel displays cutouts?
Mobiflight can work by itself, but will have limited functionality. However, paired with PMDG or prosim,you can make every aspect of the sim come to life. For all links, downloads and files visit www.737diysim.com
Hello Karl i really like your videos and since i started to build my own cockpit i watch your videos. So my question is do i have to pay for the prosim ? And can you help me for more details abour the wiring so sorry i m stoke. Best regards
Hello Venel, Prosim is expensive but if your building a full cockpit then yes you are eventually going to have to bite the bullet and purchase it. Until then you can use it for free in 30 minutes blocks before it resets. But it does keep all your data. There are other options available such as PMDG and XPLANE both offering much cheaper options, but lack in functionality and simplicity of PROSIM. Kind Regards Karl
Hi Kenji, I Believe Prosim and PMDG use similar lines of codes and are not compatible when installed into PMDG. However, you can trial Prosim free, but you will need to reset the server every 30 minutes.
Hello Dolf, I think the standard is 0.36". But i recommend getting the ones with the max7219 boards attached. There's much more info on the website under the getting started menu. Kind Regards Karl
Hi AlphaBravo1, It really depends on your software. If its PMDG then they are fixed. If you are using prosim, I would try the FSUIPC recommended offsets in the documentation, but then use mine if that doesn't work. You will probably already notice that i have two different offsets for the DIY MCP and my MCP. This is because the DIY MCP was just a test piece, but i used my own offsets in the full build. I started out at 5300 and used them sequentially as i needed. For me, as long as mobiflight and prosim have the same unused/unassigned offset, they work fine.
Hello!! how are you? I have a question, do you know if more than one Arduino board can be connected and programmed in Mobi Flight? I can connect two Arduino boards? Greetings from Argentina!
Hello Again, The ender 3 pro will produce 80% of the parts i have designed, but you will need a larger printer for others, such as the new throttle quadrant.
Hello, sorry for the delay. Yes any number can display the decimal point by selecting it in the output config page of the desired output line in mobiflight.
Hi Micheal, There are two ways really. The proper way is to download the FSUIPC documentation and there is a huge list of predetermined offsets to use. Find the item you require in the list and read across to find its offset and word length. There are free offsets to use that you can assgn to anything from 66C0 to 66FF. Once i complete the fwd overhead rewire, i will publish all my sim offsets to the website: www.737DIYSIM.com
@@helimech8152 Karl, in your MCP switches PDF, as an example you used an Offset=5300, but I can't find that Offset listed any where in the FSUIPC list. Where does one find these codes, are their other FSUIPC list available elsewhere? Is it from an Prosim SDK? I have no knowledge of programming so excuse me for asking what may be basic.
Hi Micheal, you wont find the offset 5300 because I have basically cheated and used a reserved offset for future applications. The actual list can be found by typing version 4 fsuipc offsets into google or looking in the documentation folder where you installed fsuipc into the sim.
