Hi,
ich habe das Problem, dass ich ein 12x6 Sensor-Array habe und wenn ich mir im seriellen Monitor die Werte ausgeben lasse, dann ist das ganze verkehrt rum.
Also ich habe eine Matte mit 12x6 Sensoren gebaut. Belaste ich nun z.B. die unterste Reihe der Sensormatte (12 von 12) so zeigt mir der serielle Monitor die Belastung aber in der ersten Reihe des Arrays an (1 von 12).
Wo steckt der Fehler? :o
Hier der Code dazu:
//Mux control pins for analog signal (SIG_pin)
const byte s0 = 13;
const byte s1 = 12;
const byte s2 = 11;
const byte s3 = 10;
//Mux control pins for Output signal (OUT_pin)
const byte w0 = 9;
const byte w1 = 8;
const byte w2 = 7;
const byte w3 = 6;
//Mux in "SIG" pin
const byte SIG_pin = 0;
//Mux out "SIG" pin
const byte OUT_pin = 5;
//Row and Column pins
const byte STATUS_pin = 3;
const byte COL_pin = 2;
const boolean muxChannel[16][4]={
{0,0,0,0}, //channel 0
{1,0,0,0}, //channel 1
{0,1,0,0}, //channel 2
{1,1,0,0}, //channel 3
{0,0,1,0}, //channel 4
{1,0,1,0}, //channel 5
{0,1,1,0}, //channel 6
{1,1,1,0}, //channel 7
{0,0,0,1}, //channel 8
{1,0,0,1}, //channel 9
{0,1,0,1}, //channel 10
{1,1,0,1}, //channel 11
{0,0,1,1}, //channel 12
{1,0,1,1}, //channel 13
{0,1,1,1}, //channel 14
{1,1,1,1} //channel 15
};
//incoming serial byte
int inByte = 0;
int valor = 0; //variable for sending bytes to processing
int calibra[13][7]; //Array 72 sensors
int minsensor=254; //Variable for staring the min array
int multiplier = 254;
int pastmatrix[13][7];

}
}

int readMux(byte channel){
byte controlPin[] = {s0, s1, s2, s3};
//loop through the 4 sig
for(int i = 0; i < 4; i ++){
digitalWrite(controlPin[i], muxChannel[channel][i]);
}
//read the value at the SIG pin

return val;
}
void writeMux(byte channel){
byte controlPin[] = {w0, w1, w2, w3};
//loop through the 4 sig
for(byte i = 0; i < 4; i ++){

}
}
void establishContact() {
while (Serial.available() <= 0) {
Serial.print('A'); // send a capital A
delay(300);
}
}
und die Anschlüsse stimmen dann auch nicht, also muss der Fehler irgendwo im Arduino Code liegen.
