Multiple button matrix and common GND

[kevinyao975]

Hello! Is freejoy support multiple button matrix on the same board? The reason why I need that is because I have a 4 way switch, and I don't want put it with the 55 button matrix. But after I connected and set(Button_Vcc4 & Button GND1) freejoy to read 4 way switch input, it can only show as a physical button no matter which direction I toggle. I have also wire 3 more GND from the original com, and set freejoy to Button_Vcc4 & Button GND4, the answer is still one button being recognized. Please help me with this 4 way switch work, my project is so close to the end. Now the only solution I can come out is marge 4 way switch to 55 button matrix, but I really don't wanna put it in this way. Thank for freejoy team!

I have merged everything to a single matrix, so the problem is now solved. But still looking forward to have a common GND solution.
