I have tried a few different methods (bounce update, and boolean) to digitalwrite to a specific pin on the 4051, and then read the in/out pin to see when the button has been pressed. but it has not worked... I found this helpful tutorial - http://www.gammon.com.au/forum/?id=11976 but I cannot...

Hey PAul, thanks for the reply. I was aware of the limitations regarding the 4051 driving outputs, and so perhaps I wasn't clear in the first post. I won't have any leds on the 4051 pins, but rather the switches solely, driving the leds on teensy pins. It's a tight fit but I think i will be...

I have researched widely on the 4051 multiplex chip on the internet, and found some useful info. But I have not been able to deduce a code that fit's my needs. I am trying to use the 4051 to read eight buttons (momentary switches), and then write to led's depending on the buttons latest...

int bank = PIN_B2; int button3 = PIN_B3; int ledPin4 = PIN_B4; int ledPin5 = PIN_B5; int ledPin6 = PIN_B6; int mode = 0; boolean reading2 = false; boolean reading3 = false; boolean reading3b = false; void setup() { pinMode(PIN_B2, INPUT_PULLUP); pinMode(PIN_B3, INPUT_PULLUP)...

Well, I feel like I have tried this in numerous ways, and Paul's thought to use the 'mode' variable scope tack seems to be the best route, but I am still not getting the results I seek. I have tried adapting the 'working' code from the top here to use along with the mode variable. But the...

or couldn't I just use the state of 'bank' to act like the mode - if (state2 == HIGH) { //do whatever button3 does in normal mode } else { //do whatever button3 does in altered mode } ?

hmm, well this seems to work up until I try to get the leds to join in... I got the one switch to act as a bank just as you offered, (changing button 3's actions) and the corresponding 'bank' led lights up and turns off as expected, but the button3's corresponding leds won't act appropriately...

Hello teensy gang! I have a keyboard foot controller project that I have been working on, but I hit a problem... I want to have 12 buttons and two leds for each button, and then one other button (with one, or two, leds). The last button I want to act as a 'bank switch', so that it changes the...
