Using PSoC Creator July 16, 2011 Lloyd Moore, President/Owner 

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
