What would be the coding for that? I found some Librarys for the Multiplexer but with no information how to conenct them together. Joystick.h documetation hints at being able to handle multiplexers or shift registers, but I cannot find that.I want to connect some multiplexer to my Arduino.įirst question is can i connect all S0-S3 together and control them only with the SIG pins? If you add a few more pushbuttons, put them on some random C# pins and use those numbers in the call to myDigitalRead() for testing. alternate to the if/else bit setting linesĭigitalWrite(S0, (inputCH & 0x1) ? HIGH : LOW) Īt least you can play with this toy program and see how myDigitalRead() sets the address, then reads the actual pin, then returns with that value which is 1 or 0 depends on switch open or closed. Return (!digitalRead (dig_in)) // for pulled up input - presst = LOW If (inputCH & 0x8) digitalWrite(S3, HIGH) else digitalWrite(S3, LOW)

If (inputCH & 0x4) digitalWrite(S2, HIGH) else digitalWrite(S2, LOW) If (inputCH & 0x2) digitalWrite(S1, HIGH) else digitalWrite(S1, LOW) If (inputCH & 0x1) digitalWrite(S0, HIGH) else digitalWrite(S0, LOW) Unsigned char myDigitalRead(unsigned char inputCH, unsigned char dig_in)

Serial.println(myDigitalRead(0, digital)) ĭelay(500) // just to cut down on spamming to the serial monitor PinMode(digital, INPUT_PULLUP) // or use an external pullup resistor 10K # define digital 9 // mux signal input pin Note that I invert the actual digitalRead with the '!' operator, logical negation (up is down, down is up) to compensate for using normally pulled up input.Īlso in a comment a different way to do the address pin manipuklation for your consideration. Here (compiles, untested, based on your code) is a complete sketch for just the multiplexer. It is necessary to provide for when the button is open, that is the roll of a pull up resistor.ġ0K will be fine to steer the logic HIGH when the switch is not closed. It is preferred to have each push button wired between its respective input pin C# on the mux to GND rather than 5 volts. If(inputCH & 0x8) digitalWrite(S3, HIGH) else digitalWrite(S3, LOW) If(inputCH & 0x4) digitalWrite(S2, HIGH) else digitalWrite(S2, LOW) If(inputCH & 0x2) digitalWrite(S1, HIGH) else digitalWrite(S1, LOW) If(inputCH & 0x1) digitalWrite(S0, HIGH) else digitalWrite(S0, LOW) Unsigned myDigitalRead(short inputCH, short dig_in) Serial.println(myDigitalRead(0,digital)) I tried this code, but nothings happens // USB Joystick with hall effect sensors The truth is not if I am correctly connected the arduino to the mux Value = map(analogRead(T_PIN) + T_TRIM, T_MIN, T_MAX, -512, 512) * T_INVERT Value = map(analogRead(R_PIN) + R_TRIM, R_MIN, R_MAX, -512, 512) * R_INVERT Value = map(analogRead(Y_PIN) + Y_TRIM, Y_MIN, Y_MAX, -512, 512) *Y_INVERT Int value = map(analogRead(X_PIN) + X_TRIM, X_MIN, X_MAX, -512, 512) * X_INVERT tButton(0, !digitalRead(3)) //pin 2 LOW means button 0 PRESSED Change pins and button numbers here, if you want to have different number connected to different pin We will sendState() at the end of the loop Joystick.begin(false) //false = dont send automatically. True, true, false, // X and Y, but no Z Axisįalse, false, false) // No accelerator, brake, or steering Joystick_ Joystick(0x04,JOYSTICK_TYPE_JOYSTICK, Calibrating your joystick in Windows achieves the same thing change these to change trim and limits. to change button connections, scroll down to loop()

change these to define which pins your hall effect sensors or potentiometers are connected. NOTE: This sketch file is for use with Arduino Leonardo and

The code without including anything from the MUX is this: // USB Joystick with hall effect sensors

I am using Arduino Pro Micro + Mux cd74hc4067 I have tried to modify it learning from other codes but really everything works wrong. The issue is that I don't know how to include it in the code I used without MUX. I am making a hotas controller for flight video games (personal use), and I need to separate more inputs through a MUX. I would like to request your help, I am somewhat new to this Arduino, and there are things I can't understand.
