I am using following code to attach 4 servos. I want to get back the channel number used by the attach command, but this is always 1. Why can't I get the channel number after the call to attach?
define PIN_TURNOUT_0 16 // PWM Turnout 0
define PIN_TURNOUT_1 17 // PWM Turnout 1
define PIN_TURNOUT_2 18 // PWM Turnout 2
define PIN_TURNOUT_3 19 // PWM Turnout 3
sg90_0.setPeriodHertz(50); // PWM frequency for SG90 #0
sg90_1.setPeriodHertz(50); // PWM frequency for SG90 #1
sg90_2.setPeriodHertz(50); // PWM frequency for SG90 #0
sg90_3.setPeriodHertz(50); // PWM frequency for SG90 #1
int SG0 = sg90_0.attach(PIN_TURNOUT_0, 500, 2400); // Minimum and maximum pulse width (in µs) to go from 0° to 180
Serial.printf("Channel for Servo %d \n", SG0);
int SG1 = sg90_1.attach(PIN_TURNOUT_1, 500, 2400); // Minimum and maximum pulse width (in µs) to go from 0° to 180
Serial.printf("Channel for Servo %d \n", SG1);
int SG2 = sg90_2.attach(PIN_TURNOUT_2, 500, 2400); // Minimum and maximum pulse width (in µs) to go from 0° to 180
Serial.printf("Channel for Servo %d \n", SG2);
int SG3 = sg90_3.attach(PIN_TURNOUT_3, 500, 2400); // Minimum and maximum pulse width (in µs) to go from 0° to 180
Serial.printf("Channel for Servo %d \n", SG3);
Output :
Channel for Servo 1
Channel for Servo 1
Channel for Servo 1
Channel for Servo 1
