C™ DEMO
The F1 Evaluation Platform demos are located at www.microchip.com/F1Eval. The
following demos are available:
1. I
2. LCD Demo
3. BLDC Demo
4. Combined Demo
This chapter provides an overview to the functions provided by these demos.
The I
temperature sensor. The I
converted to a PWM duty cycles and used to control the brightness of the LED D4. LED
D1 toggles at approximately 10 ms.
The LCD demo adds button, potentiometer, Real-Time Clock (RTC) and LCD support
to the I
and to drive the LCD peripheral. An input driver is supplied to manage the button and
potentiometer. A state machine now controls the major features of the demo so that the
time, temperature and potentiometer value can be displayed on the LCD.
The BLDC demo controls a sensorless, brushless DC motor connected to the PIC16F1
BLDC Expansion board (DM164130-2). Other motors can also be driven by making
appropriate modifications to the motor control parameters in the source code.
The combined demo combines all the software from all the previous demos to show the
power of the PIC16LF1937. In this demo, the BLDC motor is seamlessly controlled
while displaying the time, temperature, potentiometer position or motor RPM/10. All
drivers are reused from the previous demos. The RTCC is driven from the LCD
peripheral.
The combined demo is preprogrammed in the F1 Evaluation Platform.
