3.0.1 The Analog Multiplexer System

The Analog Mux Bus can connect to every GPI/O pin in ports 0-5.

Pins are connected to the bus individually or in any combination.

The bus also connects to the analog system for analysis with

comparators and analog-to-digital converters. It is split into two

sections for simultaneous dual-channel processing. An

additional 8:1 analog input multiplexer provides a second path to

bring Port 0 pins to the analog array.

Switch control logic enables selected pins to precharge continu-

ously under hardware control. This enables capacitive

measurement for applications such as touch sensing. Other

multiplexer applications include:

■ Track pad, finger sensing.

■ Chip-wide mux that allows analog input from up to 48 I/O pins.

■ Crosspoint connection between any I/O pin combinations.

When designing capacitive sensing applications, refer to the

Notes, which are found under http://www.cypress.com > Design

Resources > Application Notes. In general, and unless otherwise

noted in the relevant Application Notes, the minimum

signal-to-noise ratio (SNR) for CapSense applications is 5:1.

complete systems. Additional resources include a multiplier,

decimator, low voltage detection, and power on reset. Brief state-

ments describing the merits of each resource follow.

The quickest way to understand PSoC silicon is to read this data

sheet and then use the PSoC Designer Integrated Development

Environment (IDE). This data sheet is an overview of the PSoC

integrated circuit and presents specific pin, register, and

electrical specifications.

■ Full-Speed USB (12 Mbps) with 5 configurable endpoints and

256 bytes of RAM. No external components required except

two series resistors. Wider than commercial temperature USB

operation (-10°C to +85°C).

5.1.4 Code Generation Tools

5. Development Tools

PSoC Designer supports multiple third party C compilers and

assemblers. The code generation tools work seamlessly within

the PSoC Designer interface and have been tested with a full

range of debugging tools. The choice is yours.

PSoC Designer is a Microsoft^®Windows-based, integrated

development

environment

for

the

Programmable

System-on-Chip (PSoC) devices. The PSoC Designer IDE runs

on Windows XP or Windows Vista.

This system provides design database management by project,

an integrated debugger with In-Circuit Emulator, in-system

programming support, and built-in support for third-party

assemblers and C compilers.

Assemblers. The assemblers allow assembly code to merge

seamlessly with C code. Link libraries automatically use absolute

addressing or are compiled in relative mode, and linked with

other software modules to get absolute addressing.

PSoC Designer also supports C language compilers developed

specifically for the devices in the PSoC family.

C Language Compilers. C language compilers are available

that support the PSoC family of devices. The products allow you

to create complete C programs for the PSoC family devices.

5.1 PSoC Designer Software Subsystems

The optimizing C compilers provide all the features of C tailored

to the PSoC architecture. They come complete with embedded

libraries providing port and bus operations, standard keypad and

display support, and extended math functionality.

5.1.1 System-Level View

A drag-and-drop visual embedded system design environment

based on PSoC Express. In the system level view you create a

model of your system inputs, outputs, and communication inter-

faces. You define when and how an output device changes state

based upon any or all other system devices. Based upon the

design, PSoC Designer automatically selects one or more PSoC

Mixed-Signal Controllers that match your system requirements.

5.1.5 Debugger

The PSoC Designer Debugger subsystem provides hardware

in-circuit emulation, allowing you to test the program in a physical

system while providing an internal view of the PSoC device.

Debugger commands allow the designer to read and program

and read and write data memory, read and write I/O registers,

read and write CPU registers, set and clear breakpoints, and

provide program run, halt, and step control. The debugger also

allows the designer to create a trace buffer of registers and

memory locations of interest.

PSoC Designer generates all embedded code, then compiles

and links it into a programming file for a specific PSoC device.

5.1.2 Chip-Level View

The chip-level view is a more traditional integrated development

environment (IDE) based on PSoC Designer 4.4. Choose a base

device to work with and then select different onboard analog and

digital components called user modules that use the PSoC

blocks. Examples of user modules are ADCs, DACs, Amplifiers,

and Filters. Configure the user modules for your chosen

application and connect them to each other and to the proper

pins. Then generate your project. This prepopulates your project

with APIs and libraries that you can use to program your

application.

5.1.6 Online Help System

The online help system displays online, context-sensitive help

for the user. Designed for procedural and quick reference, each

functional subsystem has its own context-sensitive help. This

system also provides tutorials and links to FAQs and an Online

Support Forum to aid the designer in getting started.

5.2 In-Circuit Emulator

The device editor also supports easy development of multiple

configurations and dynamic reconfiguration. Dynamic

configuration allows for changing configurations at run time.

A low cost, high functionality ICE (In-Circuit Emulator) is

available for development support. This hardware has the

capability to program single devices.

5.1.3 Hybrid Designs

The emulator consists of a base unit that connects to the PC by

way of a USB port. The base unit is universal and operates with

all PSoC devices. Emulation pods for each device family are

available separately. The emulation pod takes the place of the

PSoC device in the target board and performs full speed (24

MHz) operation.

You can begin in the system-level view, allow it to choose and

configure your user modules, routing, and generate code, then

switch to the chip-level view to gain complete control over

on-chip resources. All views of the project share a common code

editor, builder, and common debug, emulation, and programming

tools.

6.3 Organize and Connect

6. Designing with PSoC Designer

You can build signal chains at the chip level by interconnecting

user modules to each other and the I/O pins, or connect system

level inputs, outputs, and communication interfaces to each

other with valuator functions.

The development process for the PSoC device differs from that

of a traditional fixed function microprocessor. The configurable

analog and digital hardware blocks give the PSoC architecture a

unique flexibility that pays dividends in managing specification

change during development and by lowering inventory costs.

These configurable resources, called PSoC Blocks, have the

ability to implement a wide variety of user-selectable functions.

In the system-level view, selecting a potentiometer driver to

control a variable speed fan driver and setting up the valuators

to control the fan speed based on input from the pot selects,

places, routes, and configures a programmable gain amplifier

(PGA) to buffer the input from the potentiometer, an analog to

digital converter (ADC) to convert the potentiometer’s output to

a digital signal, and a PWM to control the fan.

The PSoC development process can be summarized in the

following four steps:

1. Select components

2. Configure components

3. Organize and Connect

4. Generate, Verify, and Debug

In the chip-level view, perform the selection, configuration, and

routing so that you have complete control over the use of all

on-chip resources.

6.4 Generate, Verify, and Debug

6.1 Select Components

When you are ready to test the hardware configuration or move

on to developing code for the project, perform the “Generate

Application” step. This causes PSoC Designer to generate

source code that automatically configures the device to your

specification and provides the software for the system.

Both the system-level and chip-level views provide a library of

prebuilt, pretested hardware peripheral components. In the

system-level view, these components are called “drivers” and

correspond to inputs (a thermistor, for example), outputs (a

brushless DC fan, for example), communication interfaces

(I C-bus, for example), and the logic to control how they interact

with one another (called valuators).

Both system-level and chip-level designs generate software

based on your design. The chip-level design provides application

programming interfaces (APIs) with high level functions to

control and respond to hardware events at run-time and interrupt

service routines that you can adapt as needed. The system-level

design also generates a C main() program that completely

controls the chosen application and contains placeholders for

custom code at strategic positions allowing you to further refine

the software without disrupting the generated code.

In the chip-level view, the components are called “user modules”.

User modules make selecting and implementing peripheral

devices simple, and come in analog, digital, and mixed signal

varieties.

6.2 Configure Components

Each of the components you select establishes the basic register

settings that implement the selected function. They also provide

parameters and properties that allow you to tailor their precise

configuration to your particular application. For example, a Pulse

Width Modulator (PWM) User Module configures one or more

digital PSoC blocks, one for each 8 bits of resolution. The user

module parameters permit you to establish the pulse width and

duty cycle. Configure the parameters and properties to

correspond to your chosen application. Enter values directly or

by selecting values from drop-down menus.

A complete code development environment allows you to

develop and customize your applications in C, assembly

language, or both.

The last step in the development process takes place inside the

PSoC Designer’s Debugger subsystem. The Debugger

downloads the HEX image to the In-Circuit Emulator (ICE) where

it runs at full speed. Debugger capabilities rival those of systems

costing many times more. In addition to traditional single-step,

run-to-breakpoint and watch-variable features, the Debugger

provides a large trace buffer and allows you define complex

breakpoint events that include monitoring address and data bus

values, memory locations and external signals.

Both the system-level drivers and chip-level user modules are

documented in data sheets that are viewed directly in the PSoC

Designer. These data sheets explain the internal operation of the

component and provide performance specifications. Each data

sheet describes the use of each user module parameter or driver

property, and other information you may need to successfully

implement your design.
