User Manual

This example is similar to the 1 drive example, but instead of using just 1 PWM driver, we'll make an array called drives

that contains the pin numbers of 4 PWM drivers. Then we can assign them using crickit.analogWrite(drives[0],

CRICKIT_DUTY_CYCLE_MAX); or iterate through them as we do in the loop. You don't

have

to do it this way, but its very

compact and doesn't take a lot of code lines to create all 4 drivers at once!

#include "Adafruit_Crickit.h"

Adafruit_Crickit crickit;

#define NUM_DRIVES 4

int drives[] = {CRICKIT_DRIVE1, CRICKIT_DRIVE2, CRICKIT_DRIVE3, CRICKIT_DRIVE4};

void setup() {

Serial.begin(115200);

Serial.println("4 Drive demo!");

if(!crickit.begin()){

Serial.println("ERROR!");

while(1);

}

else Serial.println("Crickit started");

//our default frequency is 1khz

for(int i=0; i<NUM_DRIVES; i++)

crickit.setPWMFreq(drives[i], 1000);

}

void loop() {

for(int i=0; i<NUM_DRIVES; i++){

//turn all the way on

crickit.analogWrite(drives[i], CRICKIT_DUTY_CYCLE_OFF);

delay(100);

//turn all the way off

crickit.analogWrite(drives[i], CRICKIT_DUTY_CYCLE_MAX);

delay(100);

}
