Project: IntensityLED
Project Description
This example code uses a pulse-width modulator (PWM) to illuminate an LED. When the pulse width
of the PWM varies, the LED brightness changes. By continuously varying the pulse width of the
PWM, the example code makes an LED go from low brightness to a high brightness and back.
Hardware Connections
No hardware connections are required for this project, because all the connections are hard-wired to
specific pins on the board.
Verify Output
When the example code is built and programmed into the device, reset the device by pressing the
Reset button or power cycling the board.
The project output is LED3 glowing with a brightness control that changes with time (see
Figure 5-6. Verify Output - Code Example
Project: LowPowerDemo
Project Description
This example project demonstrates the low power functionality of PSoC 5. The project implements
an RTC based code, which goes to sleep and wakes up on the basis of switch inputs.
The RTC uses an accurate 32-kHz clock generated using the external crystal provided on the board.
When there is a key press, the device is put to sleep while the RTC is kept active.
Hardware Connections
The project requires a 3.3 V LCD to view the time display. No extra connections are required for
project functionality. To make low power measurements using this project, refer and implement the
changes proposed in
