hey guys I've been getting this error in my code for the wireless Arduino module is anything I'm doing wrong in my code or a way to fix it this is my first time using this module.
here's my code#include <Servo.h>#include <SPI.h>#include "RF24.h" Preformatted text
int positionA = 90;
boolean lastButton2 = LOW;
int joystick[6];
RF24 radio(7,8);

positionA++;
myServoA.write(positionA);

myServoA.write(positionA);

myServoB.write(positionB);

Hello,
Welcome to the Arduino Forum.
This guide explains how to get the best out of this forum. Please read and follow the instructions below.
Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is fru…
The code compiles for me
Please post the full error message copied from the IDE using the "Copy error message" button and use code tags when you post it
Which Arduino board are you using ?
heres the full errorPreformatted textPreformatted text
and this is the code line which i get the error done = radio.read(joystick, sizeof(joystick) );
Please do us all a favour and edit your posts and add code tags to your code and error message
done = radio.read(joystick, sizeof(joystick) );
The read() function does not return a value, hence the error message
void read(void* buf, uint8_t len);
The error message indicates that radio.read() does not return a value.
At least for the library used. Are these two libraries different?
does anyone have a fixed soltion for this line i feel like this one line is not allowing my 2 joysticks to controle my servos and i cant seem to fix this line of code
The fix is not to try and read a non existent return value from the read() function. If you want/need to ensure that the joystick value has been read then use read() in a while loop, test the value joystick within it and exit when a value has been received
