Overview





Recap from last presentation
IDE Overview
Prebuilt Components
Bubble Level Project
Live Demo
From Last Time….



The PSoC processor integrates programmable
analog and digital with a traditional processing
core
The PSoC can be a one chip solution for many
robotics projects
Develop the hardware configuration first and
then develop the software, leaving time to
experiment with different configurations
PSoC Creator IDE

PSoC Creator – Full IDE



Pretty similar to Visual Studio or Eclipse
Hardware aspects programmed with a schematic capture style tool
Integrated programmer / debugger
Component Catalog


Contains a set of pre-built hardware and software
components
Each component has 4 aspects






Schematic symbol
Datasheet
Configuration dialog
‘C’ API
To use a component drag it onto your schematic design
Right click on the part to open the datasheet or
configuration dialog
Components Available

Yes there are LOTS of them, and you can make more yourself!!!
Delta Sigma ADC Component

Implements a variable width Delta Sigma
ADC using dedicated on chip resources
Delta Sigma ADC Datasheet




Similar
format to IC
datasheets
Quite
detailed
API section
in all
Sample code
available
Delta Sigma Configuration






Multiple
configurations
Selectable resolution
Differential or Single
Ended
Selectable input gain
Selectable reference
Symbol will change
based on some
settings
Delta Sigma API (Partial)






?_Init
?_Enable
?_Start
?_Stop
API for most
config options
API for utility
functions
Bubble Level Project



PSoC 5 First Touch kit includes a 3 axis
accelerometer (KXSC7-2050)
Will use the X-axis of this accelerometer
with the 8 LEDs on board to make a
simple bubble level
This example derived from the stock
Cypress example doing the same thing
Accelerometer Configuration

Normal Mode: Continuous output, self test
off, no motion interrupt
Bubble Level Project Steps








Create a new project
Choose and configure hardware components
Setup system configuration and pin assignments
Build
Write ‘C’ code
Build
Program target
Test
Live Demo
