What
is new in version 1.2?
Version 1.2 greatly simplifies installation by removing any dependencies
on Microsoft .NET. It also fixes some minor issues (see release
notes).
Version 1.1
This version includes support for the new 8C27xxx family of microcontrollers.
A driver has been added to support the hardware based Inter-Intergrated Circuit
(I2C) controller contained in this family. The driver supports master, slave
and both modes simultaneously.
The SPI master and SPI slave drivers have been improved
to handle data overrun detection and recovery. Enhancements in the SPI slave
driver allow data transfers
to be terminated on the de-assertion of an external chip select signal
which allows for variable length messages (at run-time) from an external
SPI master. Back to top

What
is PSoC™?
PSoC devices consist of mixed signal arrays
with on-chip controllers. These
devices are designed to replace multiple traditional MCU-based system components
with one, low cost,
single-chip programmable component. PSoC devices include configurable blocks
of both analog and digital
logic components, as well as programmable interconnects. The architecture
allows the
user
to create customized
peripheral configurations that match the requirements of specific applications.
The family includes a fast
CPU, flash program memory, SRAM data memory, and configurable IO pins in
a variety of packages. Detailed information about the PSoC architecture and
development
kits are available on Cypress
MicroSystems' web site. Back to top.
Why should I use CodePalette?
The CodePalette tool can generate system software tailored
for extremely memory constrained microcontrollers. The system software
was designed with traditional features of embedded software along with
microcontroller specific optimizations and peripheral hardware device drivers.
This eliminates
much of the experimental work a developer would need in order to finely
tune
code and work out specific issues or nuisances of the microcontroller
design. Rather than re-invent some of the required "plumbing" of
an embedded system, the developer can concentrate on implementing the desired
functionality
using a higher level of abstraction. The developer can alter any aspect
of the system software to further optimize their application.
What does CodePalette for
PSoC do for me?
CodePalette for PSoC allows you to very quickly create all of the customized
support code necessary to control your specific configuration of PSoC. After
configuring the device to your application needs in the PSoC Designer (supplied
by Cypress), you run through the selection pages of the CodePalette Wizard.
You choose only the code and features that you require in your application.
You
pick the methods of scheduling tasks, the specific device driver support
needed, the power management approach, along with specific details of how
you want
each device to operate. The wizard generates high quality C code from a tested
base. You can then edit the specific tasks to perform the high level operations
that perform the functionality of your application. Using CodePalette gets
you high quality, maintainable code developed in the shortest time frame. Back

Where does CodePalette
fit into the development tool chain?

Task Scheduling
- Non-preemptive, Low-overhead
- Periodic Tasks, based on the Sleep timer, 8-bit hardware timer or 16-bit
hardware timer.
- Execute once per period. Periods based on any number
of system timer ticks.
- Continuous Tasks, run continuously in the background while the system
is powered up.
- Execute once per scheduling loop.
- Event-driven Tasks
- Execute based on an application or device event being set.
- RAM usage – 2-bytes per task Back to top.
What on-chip devices are supported?
- Serial Ports – supports two UARTs, transmit-only, receive only
or bi-directional, full duplex, buffered I/O.
- PWM – pulse width modulation drivers, 8 or 16-bit width.
- Analog to Digital Converter - 12-bit incrementing with built in variable
size FIFO.
- SPI Bus - SPI master support, SPI slave support, with variable length
message size. Back to top.
What power management options are available?
The PSoC system can operate in a number of power level states. These states
are controlled by software. CodePalette generates code that provides an
an optional power policy implementation. The code allows you to easily specify
when the processor will go into sleep mode and what devices will be also
put into sleep mode. This allows you to create optimum battery life conserving
code. There are four basic power levels created by the CodePalette. The meaning
and implementation
of
all
levels
are user
re-definable.
The default levels are:
What is the RAM and ROM footprint?
General system RAM/ROM sizes:
- 2-bytes RAM per task
- 1-bytes RAM per 8 Events
- Scheduler: ~272 bytes of ROM
- Event APIs: ~152 bytes of ROM
- Power manager: <600 bytes of ROM (configurable to be smaller)

How extensible is the generated
code?
CodePalette generates code based on a very extensible software architecture.
You can easily add additional tasks to system, modify any of the device drivers,
interrupt routines, power management approach or even the scheduler. CodePalette
does not ship with any object code libraries. The output of the Wizard contains
all of the source code necessary to build your application. Back

How can I try CodePalette for PSoC?
CodePalette
for PSoC is also available for purchase on a 30-day money back guarantee.
You
can
use the
product for
30-days
and return it for
a full refund if it
doesn't meet your needs. CodePalette comes with 60-days of e-mail technical
