Emerson Schmidt Posted August 29, 2019 Report Share Posted August 29, 2019 Hi Paul, Emerson (from Virtual Aviation) again! My LandGear is finalized. Everything's fine. Now I'm in another challenge. To export flaps offset 0BDC to a servo on arduino board. Could you help me out in this new challenge? Here's part of my code in C# (see red bold font) 1-Setting the offset: // ===================================== // DECLARE OFFSET // ===================================== private Offset<int> flaps = new Offset<int>(0x0BDC); 2-Loop timerMain : private void timerMain_Tick(object sender, EventArgs e) { // Call process() to read/write data to/from FSUIPC // We do this in a Try/Catch block incase something goes wrong try { FSUIPCConnection.Process(); // Update the information on the form // (See the Examples Application for more information on using Offsets). // exporting flaps data to a servo this.txtFlaps.Text = flaps.Value.ToString(); port.WriteLine(flaps.Value.ToString()); } } catch (Exception ex) { // An error occured. Tell the user. MessageBox.Show("Connection Failed\n\n" + ex.Message, "FSUIPC", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); } } configureForm(); } -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Here's the arduino firmware, very simple: #include<Servo.h> Servo base; void setup() { base.attach(8); Serial.begin(9600); } void loop() { int val=Serial.parseInt(); if(val!=0) { base.write(val); } } *************************************************************** What is working ? Paul, when FSUIPC connects and flaps are UP == 0 , at the time I change the flaps with 1 degree (first notch) flaps value == 2048 . Servo makes no movement. When I set flaps 2, flaps value == 4096 and servo moves 90 degrees approximately. Then I set flpas == 5 and and txt.flaps value == 4096 and servo keep steady (no changes). And nothing changes on servo as the values changes in txtFlaps on each new flap position is set but servo only changes from flap position 1 to 2 and 2 to 1. Flaps value from 2048 to 4096 and from 4096 to 2048. I think I have to creat a new firmware that according to each value arduino receives from C# (0 to 16383) , it set a servo position angle according to these values. Am I correct? Do you know another way to make the servo recognizes each flap notch and applying these values to the servo? I would be happy if you could help me out here. Thanks in advance.

Paul Henty Posted August 29, 2019 Report Share Posted August 29, 2019 Hi Emerson, The C# code looks fine and it sound like you are getting sensible values from FSUIPC. (I think you made a mistake here though (in red) as the the number should change from 2 to 5 degrees) >> When I set flaps 2, flaps value == 4096 and servo moves 90 degrees approximately.

Am I correct? Yes possibly. I don't know what values your servos need to make them move. At the moment you are just sending the raw flaps values. It would be a lucky coincidence if those were the same values the servo needs. It's likely that you will need to do some maths to translate the flaps value into the correct range for the servo. If you can explain to me what values are needed to make the servo move I can help with that. Paul Link to comment Share on other sites More sharing options...
