Notes
External PWM - Apply an
external PWM source to
the PWM testpoint, use
MSP430 for hardware
configuration. Remove
jumper JP1.
External PWM / External
Enable - Apply an external
PWM source and enable
signal. Enable pin on
MSP430 is Hi-Z. Remove
jumper JP1.
Life Test (2 seconds on, 1
second off) - life test
repeats infinite times and
board must be powered
down to stop. Increment /
Decrement amplitude using
B3 and B4. Test new
amplitude using B2.
Life Test (Infinite Buzz) -
board must be powered
down to stop buzz.
Increment / Decrement
amplitude using B3 and B4.
Test new amplitude using
B2 before beginning life
test.
Vary the auto-resonance off
output frequency and see
the change in vibration
force over frequency.
Compare B2 (auto-
resonance off) with B1
(auto-resonance on).
Life Test (Infinite Buzz) -
board must be powered
down to stop buzz.
Increment / Decrement
amplitude using B3 and B4.
Test new amplitude using
B2 before beginning life
test.
