Error compiling for board Adafruit MacroPad RP2040

[jwhaddad]

Any chance this can be made to compile for board Adafruit MacroPad RP2040?
i get this error "Error compiling for board Adafruit MacroPad RP2040"

[ProRedCat]

It's possible this can be made to compile for the Adafruit MacroPad RP2040, is there more information from the compilation log so I can figure out what is causing the compile error?

Thank you for your reply. I'm slightly new to Arduino, have done many projects with raspberry pi. Your help is greatly appreciated.below is the complete log i get:
my arduino program:
#include <Wire.h>
#include <PCF8574_Stepper.h>
#include <PCF8574.h>

PCF8574 stepperExpander(0x20); //Create the PCF8574 object at the hex address the PCF8574 chip is at

StepperMotor mainStepper(stepperExpander, 200, 0, 1, 2, 3); //When making the new object you can either use P0, P1, P2, ect.. or use numbers
//StepperMotor mainStepper(stepperExpander, 200, 0, 1); //Config for two wire contol

void setup() {
mainStepper.setSpeed(100); //Set speed to 100RPM (This is a softcap, library has limited to 100RPM to not cause problems with missing steps, change the library if you need to)
stepperExpander.begin(); //Remember to .begin() the PCF8574 chip or else it will not output
}

void loop() {
mainStepper.step(100); //Step 100 forwards
mainStepper.step(-100); //Step 100 backwards
}

[ProRedCat]

This is an issue where Arduino supports NULL values but Adafruit does not.

You could change the code so that pin3 and pin4 are set to -1 in two-wire control mode and change the if statements to reflect this.

Below are some examples on parts of the code that should be changed

class StepperMotor {
private:
    PCF8574& stepperExpander;
    int stepsPerRev;
    int pin1, pin2, pin3, pin4;
    bool twoWire;
    int currentStep;

public:
    StepperMotor(PCF8574& stepperExpander, int stepsPerRev, int pin1, int pin2, int pin3 = -1, int pin4 = -1); CHANGE HERE
    void step(int steps);
    void setSpeed(long whatSpeed);
};

and

this->twoWire = (pin3 == -1 || pin4 == -1);
