[Paparazzi-devel] IR_RollOfIrs and IR_PitchOfIrs

Dear All,

Sorry if this is a silly question,

I'm looking at the following code at the infrared.c

void ir_update(void) {
#ifndef SIMUL
  int16_t x1_mean = buf_ir1.sum/buf_ir1.av_nb_sample;
  int16_t x2_mean = buf_ir2.sum/buf_ir2.av_nb_sample;
  ir_roll = IR_RollOfIrs(x1_mean, x2_mean) -
  ir_pitch = IR_PitchOfIrs(x1_mean, x2_mean) -
  extern volatile int16_t simul_ir_roll,
  ir_roll = simul_ir_roll - IR_ADC_ROLL_NEUTRAL; 
  ir_pitch = simul_ir_pitch - IR_ADC_PITCH_NEUTRAL;  

My problem is : where is the implementation of
IR_RollOfIrs and IR_PitchOfIrs ?

Thank You
