Hello, I bought this module from RobotDyn: http://robotdyn.com/catalog/capacitive/16_keys_capacitive_touch_ttp229_i2c_module/
I'm trying to use the code made from them, but it shows nothing on serial monitor...
The connections are:
VCC -- 5V
GND -- GND
SCL -- D1
SDA -- D0
The code is:
#include <Wire.h>
#define ttp229 (0xAF>>1)
uint16_t data_out=0;
uint16_t data1,data2;
int count=0;
boolean count2=false;
int button[16];
int oldata[16];
void setup(){
Serial.begin(9600);
Wire.begin();
}
void loop(){
Wire.requestFrom(ttp229,2,true);
delay(1);
while(Wire.available()){
data1=Wire.read();
data2=Wire.read();
data_out=(data1<<8)|data2;
for(int i=1;i<17;i++){
uint16_t contrast=0x8000;
if(data_out & contrast){
//Serial.println(i);
button[count]=i;
count++;
delay(1);
}
data_out<<=1;
}
if(count2){
switch(count){
case 1:
if(oldata[0]==button[0]){
Serial.println(button[0]);
delay(20);
}
break;
case 2:
if(oldata[0]==button[0]&&oldata[1]==button[1]){
for(int i=0;i<2;i++){
Serial.print(button[i]);
Serial.print(" ");
delay(10);
}
}
break;
}
}
delay(50);
for(int i=0;i<16;i++){
oldata[i]=button[i];
}
count=0;
count2=!count2;
}
}
Can anyone help me? Thanks
