electromotivated 0:4f0a06335fbe 4
electromotivated 0:4f0a06335fbe 5 Basic Demo of the TI DRV2605L Haptics Driver Breakout.
electromotivated 0:4f0a06335fbe 6 This code uses the MPR121 Library and modified version
electromotivated 0:4f0a06335fbe 7 of Dr. Jim Hamblen's Hello World Example for the MPR121
electromotivated 0:4f0a06335fbe 8 for Capacitive Touch Keypad for user input.
electromotivated 0:4f0a06335fbe 9
electromotivated 0:4f0a06335fbe 10 The user and touch keys 3,7,11,2,6,10, 1,5,9,and 0.
electromotivated 0:4f0a06335fbe 11 Each Key will toggle through about 10 effects each,
electromotivated 0:4f0a06335fbe 12 (key 11 toggles between 12 or 13 of the effects).
electromotivated 0:4f0a06335fbe 13 Effects are the ROM Library Haptics effects internal to
electromotivated 0:4f0a06335fbe 14 the DRV2605L Haptics Driver.
