hi,
I'm writing some code to run on a attiny44 I'm using the "high low tech" cores on arduino ide 1.0.4. the problem i'am having is the tone function is not working. does the "high low tech" cores support tone()? I've seen other's use tone() on the attiny85. Am i doing something wrong in the code or does the core not support it?
code is to be run on a attiny44 and will check the
voltage of each individual cell of a lipo/lion/life battery
and alert when a cell reaches the cuttoff voltage via a buzzer
******************************************************************/
#define low_voltage 3.3 //defines the voltage at which the alarm will sound
#define Cell_Count 3 //defines how many cells are in the battery (1-4)
#define Buzzer_Pin 5 //defines the pin connected to the buzzer
int Cell_Voltage[Cell_Count] = {0}; //array to store the cell voltages
int cell = 0;
long mark = 0;
void setup(){
pinMode(1,INPUT); //cell 1
pinMode(2,INPUT); //cell 2
pinMode(3,INPUT); //cell 3
pinMode(4,INPUT); //cell 5
pinMode(Buzzer_Pin,OUTPUT); // buzzer pin
//play ready tones
//myTone(Buzzer_Pin,2000,150);
//myTone(Buzzer_Pin,3600,200);
// myTone(Buzzer_Pin,4000,250);
// myTone(Buzzer_Pin,4700,350);
}
void loop(){
for(;cell < Cell_Count; cell++){
Cell_Voltage[cell] = analogRead(cell+1); //read the voltage of each cell one at a time and store it in the cell_voltage array
}
cell = 0; //reset cell counter
for(;cell < Cell_Count; cell++){ //compare each cells voltage to the low voltage threshold
if(Cell_Voltage[cell] <= ((low_voltage/0.0048828125)+1)){ //sound the buzzer if the voltage
digitalWrite(9,HIGH); //set pin 8 high for aux output
//play alarm tones
//myTone(Buzzer_Pin,4000,200);
//myTone(Buzzer_Pin,3500,400);
tone(Buzzer_Pin,4000,1000);
}
}
digitalWrite(9,LOW);
cell = 0; //clear cell count
}
