The Analog Multiplexer System

The Analog System

The Analog Mux Bus can connect to every GPIO pin. Pins may

be 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. An additional 8:1

analog input multiplexer provides a second path to bring Port 0

pins to the analog array.

The Analog System consists of 4 configurable blocks that allow

the creation of complex analog signal flows. Analog peripherals

are very flexible and may be customized to support specific

application requirements. Some of the common PSoC analog

functions for this device (most available as user modules) are:

■ Analog-to-digital converters (single or dual, with 8-bit or 10-bit

resolution)

Switch control logic enables selected pins to precharge

continuously under hardware control. This enables capacitive

measurement for applications such as touch sensing. Other

multiplexer applications include:

■ Pin-to-pin comparator

■ Single-ended comparators (up to 2) with absolute (1.3V)

reference or 8-bit DAC reference

■ Track pad, finger sensing.

■ 1.3V reference (as a System Resource)

■ Chip-wide mux that allows analog input from any IO pin.

■ Crosspoint connection between any IO pin combinations.

In most PSoC devices, analog blocks are provided in columns of

three, which includes one CT (Continuous Time) and two SC

(Switched Capacitor) blocks. The CY8C21x34 devices provide

limited functionality Type “E” analog blocks. Each column

contains one CT Type E block and one SC Type E block. Refer

to the PSoC Programmable System-on-Chip™ Technical

Reference Manual for detailed information on the CY8C21x34’s

Type E analog blocks.

When designing capacitive sensing applications, refer to the

signal-to-noise system level requirement found in Application

Code Generation Tools

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.

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.

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.

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 IO 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.

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.

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.

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 In-Circuit Emulator (ICE) is

available for development support. This hardware has the

capability to program single devices.

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.

property, and other information you may need to successfully

implement your design.

Designing with PSoC Designer

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.

Organize and Connect

You can build signal chains at the chip level by interconnecting

user modules to each other and the IO pins, or connect system

level inputs, outputs, and communication interfaces to each

other with valuator 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.

Select Components

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).

Generate, Verify, and Debug

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.

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.

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.

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 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
