Hans Kreuk / DRV2605_KickStartMyHeart

Modified the original DRV2605 library written by Bryce Williams. Team specific uint8_t kick_start_my_heart(int intensity, int duration) function is added to the library, otherwise unchanged. FLY ARMY!!!

Fork of DRV2605 by Bryce Williams

  1. include "mbed.h"
  2. include "DRV2605.h" DRV2605 haptics(p9, p10); *NEEDE FOR KCIKSTART*

PwmOut base(p26); *NEEDED FOR BOOSTER CIRCUIT, if required*

int main() { base.period(.000001);1MHz base=.5;50% duty cycle

*FOLLOWING NEEDED FOR KICKSTART*

haptics.init(3.3); Motor initialization will cause a 1 second vibration

wait(2);

uint8_t stats=haptics.kick_start_my_heart(10, 1); Intensity range 1-10, duratio range 1-8

printf("dig %X/n",haptics.init(3.3)); }
