assigning different PWM Ranges on RP2040_ISR_Servo, Khoih-prog

[TimRosener]

Is it possible to assign different PWM ranges for each servo setup using this library? In the examples, there appears to be a global setup for the PWM ranges; I did not see an option to setup the individual servos with specific ranges for that servo. In my case I am using a Rpi Pico W, Arduino 2.0 IDE and the non-Mbed platform.

Thanks.

HI @TimRosener

Those examples are just basic to demo how to use the features.

You can change the PWM range (min/max pulse-width) to any pulse-width range you'd like

The function to use is

RP2040_ISR_Servo/src/RP2040_ISR_Servo.hpp

Lines 160 to 161 in 281c145

	// Bind servo to the timer and pin, return servoIndex
	int8_t setupServo(const uint8_t& pin, const uint16_t& minPulseUs = MIN_PULSE_WIDTH, const uint16_t& maxPulseUs = MAX_PULSE_WIDTH, uint16_t value = 0);

In the examples, for simplification, fix values are used

RP2040_ISR_Servo/examples/RP2040_MultipleServos/RP2040_MultipleServos.ino

Lines 67 to 69 in 281c145

	// Published values for SG90 servos; adjust if needed
	#define MIN_MICROS 800
	#define MAX_MICROS 2450

such as

RP2040_ISR_Servo/examples/RP2040_MultipleServos/RP2040_MultipleServos.ino

Line 116 in 281c145

ISR_servo[index].servoIndex = RP2040_ISR_Servos.setupServo(ISR_servo[index].servoPin, MIN_MICROS, MAX_MICROS);

You can change those values, such as

ISR_servo[index].servoIndex = RP2040_ISR_Servos.setupServo(ISR_servo[index].servoPin, MIN_MICROS[index], MAX_MICROS[index]);

Perfect, thanks for the quick response!

Quick Question does your library take advantage of the 8 state machines available in the RP2040?

[khoih-prog]

No. You have to adapt yourself.

Thanks for the advice on the state machines, I found a library that was super useful in getting the state machines running for 12 servo outputs. Super Fast!
