Custom Movement Panel Mobile App Issue

I have been working on implementing a custom movement panel in Interface Builder and trying to use it via the mobile app, but I'm encountering issues. It doesn't seem to work. Can you let me know if movement panels are supposed to function in the mobile app? I am currently using an L298N motor controller. When I attempt to use the joystick or...

Assistance With C++ Map Function

Hi @Athena, I am experiencing some difficulty with the implementation of the map function in C++. Could you help me review the following code snippet to determine if it is correct? The code is designed to adjust the speed of two stepper motors based on a variable, psudoDesCrsDiffSum, which can take values from -500 to 500. cpp // leftSpeed = speed...

Triggering UART At Travel Milestones

Hello @Athena, I'm working on a project using an Arduino Mega 2560 to control stepper motors and need help with setting up recurring events that trigger at specific points during the movement. Specifically, I want to send a signal when the motors have traveled 33% and 66% of the total path endpoint distance. Here's a code snippet representing the...

Could you please provide the command for the Ultrasonic Distance Sensor within the EZ-B protocol that is not yet included in the current protocol documentation?

Switching Voltage For Sharp Sensor

Hi @Athena, I have a question about powering the Sharp IR Distance Measuring Sensor #GP2Y0A02YK0F, which I am using in my rover project. I've been experimenting with this sensor, and it has worked very well for object detection when powered with 5V DC. During my tests, I found that for specific tasks, the sensor needs to detect a reflector instead...
