• Type in the name GettingStarted
• Set destination directory Desktop/default or
  select one

50
Lets Create Our Project

• Select the Base Part
• View the drop-down menu and the catalog
• Well use CY8C26443-24PI (28 PDIP, same as the
  pod)

51
Lets Create Our Project

• Select Projects Language
• Assembly and C languages available, (C, only if
  enabled)
• Well choose assembly

52
Select User Modules

• Explore the Select Mode of Device Editor
• User Module Catalog ( tabs on left side of
  screen)
• Resource Manager (right side of screen)
• User Module Data Sheet Viewer (bottom middle of
  screen)
• Adding, Deleting, User Module Instances
• Select User Modules for this Project
• Go to the indicated tab section and double-click

• Repeat the selection and Select a second PWM16

53
Place User Modules

• Explore the Place Mode of Device Editor
• Next Position icon
• Selecting the Active UM block
• Place Here icon
• Unplace icon
• Place User Modules for this Project
• STOP!
• How do I know where to place the User Modules?
• How does PSoC Designer help me?

54
How to Place User Modules

• Try-out the modules individually first
• See how restrictive they are, then return to
  place
• PSoC Designer will only allow the modules to be
  placed where the chip can support them
• PSoC Designer will not prevent a placement that
  may create a conflict for resources
• Example If you have an ADC and temperature
  sensor, they both use the comparator bus. There
  is only one comparator bus per column, therefore
  these two UMs must reside in separate columns in
  order to be used simultaneously.
• Read the UM Data Sheets for details
• Use the Cypress MicroSystems Online Resources
• www.cypressmicro.com/support

55
Place User Modules

• Place the two selected UMs in the default
  positions.
• PWM16_1 Digital Blocks DBA00/DBA01
• PWM16_2 Digital Blocks DBA02/DBA03
• Recommend to put the PWMs in the Basic Digital
  Blocks to Save the Digital Com Blocks

56
Configure Global Resources

• CPU_Clock Set to 12MHz
• 32K_Select Set to Internal
• Not using an external crystal
• PLL_MODE Set to Disable
• PLL can only be enabled when 32K_Select is
  External (crystal)
• Sleep_Timer Set to the default value of 512_Hz.
• 24V1 24MHz/ N Set to 16
• This divides 24MHz by 16 1.5MHz
• 24V224V1/N Set to 16
• This divides the 24V1 by 16 (1.5MHz/1694kHz)
• Analog Power Set to SC On/Ref Low
• This is required to power up any of the analog
  blocks, depending on the number of analog
  functions. A Ref Med or Ref High may be required
  (and will increase power consumption)

57
Configure Global Resources

• Ref Mux Set to (Vcc/2) Bandgap (the default)
• Op-Amp Bias Set to Low (the default)
• This is not recommended as anything but low
• A_Buff_Power Set to Low (default)
• This selects the power level of the analog output
  buffer
• There is a tradeoff between drive output
• power and power consumption.
• Low is adequate for most projects
• SwitchModePump Set to Off
• VoltMonRange Set to 5.0V
• VoltMonThreshold Set to 80

58
Configure User Modules

• PWM_1 We want to generate a 1/5 duty cycle
• User module parameters can be configured in two
  ways through the GUI or through the User Module
  Parameters window. In this class we will use the
  User Module Parameters window in the left bottom
  corner.
• Set Clock to 24V2 (94kHz)
• Set Enable High to keep the PWM always running
• Set Period to 65535 (1.4Hz)
• Set PulseWidth to 13107
• Compare Type Less Then Or Equal
• Interrupt Type Terminal Count
• Set Output to Global_OUT_2

59
Configure User Modules

• PWM_1 We want to generate a 1/5 duty cycle

60
Configure User Modules

• PWM_2 We want to generate a 2/5 duty cycle
• Set Clock to 24V2 (94kHz)
• Set Enable High to keep the PWM always running
• Set Period to 65535 (1.4Hz)
• Set PulseWidth to 26214
• Compare Type Less Then Or Equal
• Interrupt Type Terminal Count
• Set Output to Global_OUT_3

61
Interconnect Blocks to Resources

• What interconnection possibilities are there?
• Device Inputs
• Device Outputs
• Clocks
• Block-to-block
• When you specify a PSoC block connection to a
  pin you are making a physical connection to the
  hardware of the PSoC device.

62
Define the Pin-out

• What pins need to be defined?
• UM Inputs
• UM Outputs
• General Purpose IO
• Block-to-block
• What pin-out options are there?
• Permanent vs. test/debug
• What happens as pins are defined?
• Pin-out our project
• LEDs
• SignalOut

63
Interconnect Blocks to Resources

• Connect PWM_1 output to the pins
• We have already enabled the output from block
  Global_Out_2
• Go to Pin 21 (Port_2 Bit 2) Enable the Port 2_2
  (top choice) pin and then Chose Global_OUT_2
  (strong)
• This will result in turning the pin dark red for
  Global Out
• Port 2 is connected to the LEDs on the Pup board.

64
Interconnect Blocks to Resources

• Connect PWM_2 output to the pins
• We have already enabled the output from block
  Global_Out_3
• Go to Pin 7 (Port_2 Bit 3) Enable the Port 2_3
  pin and then select Global_OUT_3 (strong)
• This will result in turning the pin dark red for
  Global Out
• Port 2 is connected to the LEDs on the Pup board.

65

  are made to the configuration

Now switch to the Application Editor view
66
Time to Create Application Code

  user based on the inputs from the Device Editor
  configurations.
• View the files on the left side of the
• application window. All interrupt routines,
• header files, include files, configuration

PSoC ApplicationMotor Control

• PSoC

95
PSoC user modules

• PWM_8
• Drives motor
• UART
• Used to upload speed value to PC and download
  mode to the PSoC
• Baud rate clock
• 57.6 kb/s
• Communication interval timer
• 2 Hz interrupt. Loads speed value into UART,
  updates PWM.
• PGA
• Connects thermistor network to ADC.
• Delta-Sigma ADC
• Converts thermistor input.

96
PSoC firmware

• LUT A
• Contains gain so that small temperature change
  results in large change in fan speed.
• LUT B
• Manual mode, increase in PWM duty cycle
  proportional to movement of slide control in Lab
  View.
• UART Interrupt Service Routine (ISR)
• Eliminates polling that may waste throughput.
• Communication timer ISR
• 2 Hz, updates PWM compare register, sends PWM
  duty cycle to Lab View.
• Main
• Initialize user modules, handles commands from
  Lab View
• Design will run without PC communication link

Customers cost are also reduced by fewer
components, ease of manufacturing, shorter
development time, and leverage with the reuse of
PSoC!
