![]() ![]() 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.

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 pulled down the signal pin with a 10k resistor.I would like to request your help, I am somewhat new to this Arduino, and there are things I can't understand. I would like to mention that there was a cabling issue as well. Here is the working set of code: // interfacing mux with tp223 I had failed to initialize the A0 pin as input: Since there was an elementary failure in the code as well I would like to post the solution in here: Is there a need for a pullup or pulldown resistors in this setup? Should I connect a resistor to each S0-S3 with ground? Why is this not working? Īnd I get no HIGH on channel 12 as I should. On my first run after boot: press any key to continue. With ttp123 touched, I would expect to get a high on SIG when I write Just for simplicity, I have connected only one ttp123 on the system, ttp123 signal to channel12 on 74HC4067. ") Ī= Serial.readString() // read the incoming data as stringĭigitalWrite(controlPin, muxChannel) Serial.println(" press any key to continue. Serial.println("keypad interfacing_CD74HC4067 starting.") Here is my code: //Using CD74HC4067 16-Channel Analog Multiplexer I expect when a ttp123 is pressed to trigger a HIGH and this event to be passed to SIG pin. I power the setup with a separate 5v and the arduino is connected on a pc usb port. The S0-S3 pins are connected to digital Pins 7-4 on a pro mini. ![]() Each ttp123 signal is connected to one of the 0-15 pins of the CD74HC4067. More specifically i am trying to build a keypad with multiple ttp123 break-boards. ![]() I am working on a project that needs multiple digital signals and I am considering the CD74HC4067 (on a break-board) to work as a multiplexer. ![]()
