Hi, Im helping to build an ROV for a local competition but have ran into some difficulty. My role is to provide code to help the motors operate. The motors will run off of 3, 2 input H-bridges with mosfets…
How many pwm pins should the rov need per motor? Ive been told from some people that each motor should require 2 pwm pins (Forward & Back), although ive heard from another source that each motor should have 4 pins.
FYI the ROV is to be controlled by 2 Joysticks, the left joystick will control the forwards and backwards motion of the rov when pressed up&down, and will control the vertical motion of the rov when pushed left/right. The right joystick will turn the rov.
// Joystick Settings
static const int JS_CENTER_0 = 511; // Analog reading at center, 0-1023
static const int JS_CENTER_1 = 511;
static const int JS_CENTER_2 = 511;
static const int JS_RANGE_0 = 128; // Analog range, 0-1023
static const int JS_RANGE_1 = 128; //
static const int JS_RANGE_2 = 128;
static const int JS_DIR_0 = 1; // +1 or -1
static const int JS_DIR_1 = 1;
static const int JS_DIR_2 = 1;
// Arduino Pins
static const byte JS_ADC_0 = A0;
static const byte JS_ADC_1 = A1;
static const byte JS_ADC_2 = A2;
static const byte THRUSTER_LEFT_FWD = 9;
static const byte THRUSTER_LEFT_REV = 5;
static const byte THRUSTER_RIGHT_FWD = 3;
static const byte THRUSTER_RIGHT_REV = 10;
static const byte THRUSTER_VERTICAL_UP = 11;
static const byte THRUSTER_VERTICAL_DOWN = 12;
That’s the code I have so far, If anyone has any tips on where to go now then that would be really helpful.
