new update

io spero un ATC come quello di BMS, o almeno che si avvicini

ti ho mandato pm

ciao, vendi anche separatamente?

ciao a tutti, io ho un x56 e vorrei prendere lo stick winwing. com'è? con il mio faccio una fatica bestiale a fare aar. vorrei sapere se ha laschi nei micro movimenti o se è preciso. grazie

ok, thanks a lot, always a lot of help. I'll try and see if there are no problems. again thank you very much

is it possible to make a single sketch for the commands of both 18 and 16?

this is what i use with arduino leonardo #include <Joystick.h> void setup() { // Initialize Button Pins pinMode(0, INPUT_PULLUP); pinMode(1, INPUT_PULLUP); pinMode(2, INPUT_PULLUP); pinMode(3, INPUT_PULLUP); pinMode(4, INPUT_PULLUP); pinMode(5, INPUT_PULLUP); pinMode(6, INPUT_PULLUP); pinMode(7, INPUT_PULLUP); pinMode(8, INPUT_PULLUP); pinMode(9, INPUT_PULLUP); pinMode(10, INPUT_PULLUP); // Initialize Joystick Library Joystick.begin(); } // Costante che mappa il pin fisico sul pulsante del joystick. const int pinToButtonMap = 0; // Ultimo stato del pulsante int lastButtonState[10] = {0,0,0,0}; void loop() { // Read pin values for (int index = 0; index < 6; index++) { int currentButtonState = !digitalRead(index + pinToButtonMap); if (currentButtonState != lastButtonState[index]) { Joystick.setButton(index, currentButtonState); lastButtonState[index] = currentButtonState; } } delay(50); }

hello, I use this to export the ifei via lua file. IFEI_init.lua

Can anyone help me fix the sketch?

it should be one of these or all three, I attach the image. I think it's the former but I'm not sure /*------------------------------------ Visualizzazione del numero dello scratchpad --------- ------------------------------------*/ void onUfcScratchpadNumberDisplayChange(char* newValue) { /* il tuo codice qui */ ScPad[2] = newValue; // Copia i numeri nell'array dello scratchpad nella terza posizione dell'array DisplayScrn(); // Chiama la funzione Display Screen } DcsBios::StringBuffer<8> ufcScratchpadNumberDisplayBuffer(0x7446, onUfcScratchpadNumberDisplayChange); /*----------------------------------- scratchpad visualizzazione della prima stringa --------- ---------------------------------*/ void onUfcScratchpadString1DisplayChange(char* newValue) { /* qui il tuo codice */ ScPad[0] = newValue; // Copia 1st chr nell'array dello scratchpad alla 1a posizione nell'array DisplayScrn(); // Chiama la funzione Display Screen } DcsBios::StringBuffer<2> ufcScratchpadString1DisplayBuffer(0x744e, onUfcScratchpadString1DisplayChange); /*----------------------------------- scratchpad visualizzazione seconda stringa --------- ---------------------------------*/ void onUfcScratchpadString2DisplayChange(char* newValue) { /* qui il tuo codice */ ScPad[1] = newValue; // Copia il secondo chr nell'array dello scratchpad alla seconda posizione nell'array DisplayScrn(); // Chiama la funzione Display Screen } DcsBios::StringBuffer<2> ufcScratchpadString2DisplayBuffer(0x7450, onUfcScratchpadString2DisplayChange);

as you can see all but one work. Can anyone help me fix the arduino sketch?

hello everyone, after a month of testing I managed to fix the UFC screens, but the only one I can't get to work is the screen where the radio frequency is indicated (central top) I am attaching the sketch to understand what is wrong #include <Adafruit_SSD1306.h> #include <splash.h> #define MUX_Address 0x70 // TCA9548A Encoders address #define DCSBIOS_IRQ_SERIAL #include "Wire.h" #include <U8glib.h> #include "DcsBios.h" Adafruit_SSD1306 oled(6); char* OpQue[5]; // Create Option Quing Global Array char* Dval[5]; // Create Option Display Global Array char* ScPad[3]; // Create Scratchpad Display Global Array char tmp_string[8]; // Temp string to convert numeric values to string before print to OLED display U8GLIB_SSD1306_128X32 u8g(U8G_I2C_OPT_FAST); // Fast I2C / TWI // Initialize I2C buses using TCA9548A I2C Multiplexer void tcaselect(uint8_t i2c_bus) { if (i2c_bus > return; Wire.beginTransmission(MUX_Address); Wire.write(1 << i2c_bus); Wire.endTransmission(); } /* paste code snippets from the reference documentation here */ /*------------------------------------ scratchpad number display --------------------------------------------*/ void onUfcScratchpadNumberDisplayChange(char* newValue) { /* your code here */ ScPad[2] = newValue; // Copy numbers into the scratchpad array at 3rd position in array DisplayScrn(); // Call the Display Screen function } DcsBios::StringBuffer<8> ufcScratchpadNumberDisplayBuffer(0x7446, onUfcScratchpadNumberDisplayChange); /*----------------------------------- scratchpad 1st string display -----------------------------------------*/ void onUfcScratchpadString1DisplayChange(char* newValue) { /* your code here */ ScPad[0] = newValue; // Copy 1st chr into the scratchpad array at 1st position in array DisplayScrn(); // Call the Display Screen function } DcsBios::StringBuffer<2> ufcScratchpadString1DisplayBuffer(0x744e, onUfcScratchpadString1DisplayChange); /*----------------------------------- scratchpad 2nd string display -----------------------------------------*/ void onUfcScratchpadString2DisplayChange(char* newValue) { /* your code here */ ScPad[1] = newValue; // Copy 2nd chr into scratchpad array at 2nd position in array DisplayScrn(); // Call the Display Screen function } DcsBios::StringBuffer<2> ufcScratchpadString2DisplayBuffer(0x7450, onUfcScratchpadString2DisplayChange); /*---------------------------- Option Screen Displays ------------------------------*/ void onUfcOptionDisplay1Change(char* newValue) { /* your code here */ Dval[0] = newValue; // Copy the option screen 1 data into screen array DisplayScrn(); // Call the Display Screen function.

ok, I'm almost there, I just have to figure out how to insert the central display of the comms.

I've been trying to get the ufc displays for the hornet to work for a month, but I can't, as soon as I enter the code for DCS Bios it gives me an error. how should i setup the sketch?

hello all, i have a problem with the sketch for ufc f 18. i can't get 0.91 inch screens to work. I use the TCA9548A multiplexer. I've searched the internet but the ones I've found always give me errors. Could any of you help me? thank you and wish you a happy new year

ufc finished at 90%, now I'm trying to insert 0.91 inch screens. on the left side I have the master arm with the AA and AG modes, while on the right side I have the HOOK and HMD.

ciao f1pier, stavo proprio per installare i display, hai un codice per arduino mega 2560? devo usare un multiplex per collegare i 6 quadranti alla mega vero? grazie mille per l'aiuto

Hi, I can't get the 0.91 inch screen to work for the F18 ufc. this is the sketch : #define DCSBIOS_DEFAULT_SERIAL #include <DcsBios.h> #include <SPI.h> #include <Wire.h> #include <Adafruit_GFX.h> #include <Adafruit_SSD1306.h> #define SCREEN_WIDTH 128 // OLED display ancho en pixels #define SCREEN_HEIGHT 32 // OLED display altura en pixels #define OLED_RESET -1 // Reset pin # (or -1 if sharing Arduino reset pin) Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET); int count; ///////////////////////// SETUP ////////////////////////////////////////////////////////////// void setup() { count = 0; display.begin(SSD1306_SWITCHCAPVCC, 0x3C); display.clearDisplay(); display.setTextSize(1,2); display.setTextColor(WHITE); display.setCursor(0,0); display.cp437(true); display.print("N-A-12"); display.display(); display.setTextSize(1,2); DcsBios::setup(); } /////////////////////////// LOOP //////////////////////////////////////////////////////// void loop() { DcsBios::loop(); } ////////////////////////////Config Display /////////////////////////////////////////////////////// String comDisplay[2]; void updateComDisplay(int changed,char* newValue) { comDisplay[changed] = cleanUpCom(newValue); display.clearDisplay(); display.setCursor(0,0); display.print(comDisplay[0]); display.setCursor(35,0); display.print(comDisplay[1]); display.display(); } char* cleanUpCom(char* newValue) { switch (newValue[0]) { case '`': newValue[0]='1'; break; case '~': newValue[0]='2'; break; } return newValue; } //////////////////////////////////// DISPLAY UFC F18 ///////////////////////////////////////////////////// void onUfcOptionDisplay1Change(char* newValue) { updateComDisplay(0, newValue); } DcsBios::StringBuffer<4> ufcOptionDisplay1Buffer(0x7432, onUfcOptionDisplay1Change); I put the SDA and SCK contacts on the arduino mega 2560 in A5 and A4 there is something I can't understand, it doesn't give me any kind of error

the measurements you said are more or less exact, as soon as I find where I put the usb key with the plans of 16 I put them here

as Mapi rightly said you have to add a string of code at the end to the IFEI_init.lua file. Like this: IFEI_init.lua find it here: C:\Eagle Dynamics\DCS World\Mods\aircraft\FA-18C\Cockpit\Scripts\IFEI\indicator you have to overwrite it at each update otherwise it will return as before for the other instruments I don't know where to find them, I asked the same question too but no one answered me

anyone who can explain to me how to export digital tools in monitor.lua file?

how can i insert in the lua file of the monitor also the digital instruments under the right DDI?
