Unsolved change color with a gesture 1D
-
Hi all,
i have this situation:void Luce::gesture(int result) { int valore[1000]= {0}; for (int i = 0;i< 1001;i++) { valore[i] = result; } int primo = valore[0]; int ultimo = valore[999]; qDebug()<< primo << ultimo << endl; if (primo != ultimo) { on_pushButton_released(); } else { return; } }
I create this program that receives data (result) from a serial port.
i want to create this gesture:
if result is a decreasing data (so 'primo', the first value, is higher than 'ultimo', the last data of my array) my led has to change color. It should appears like a hand that get close and closer to the range sensor.
I wrote this and compiled, but the program close forcefully and crashed.
Any idea of why and how can i resolve it?
Thanks to everybody. -
i worked on it and i change the code:
int valore[100]= {0}; int prev = 0 ; int next= 0 ; for (int i = 0;i< 100;i++) { if(i == 0) { next= prev; valore[i] = 0; //qDebug()<< "this is if"<<endl; } else { valore[i] = result; prev = valore[i-1]; next = valore[i]; // qDebug()<< " this is else"<<endl; if( prev > next) { qDebug()<<"this is my if 2"<<endl; on_pushButton_released(); } } }
