Training embedded apps to process speech may be as easy as finding the right 8-bit micro. Don t let what Rodger has to say about using an ADPCM algorithm and PWM Output to generate speech to go in one ear and out the other
OXCC is a multipass, interpreting C compiler with several language extensions. It generates an Architecture Neutral Format (ANF) Output and comes with a couple of example back ends. Programmers are expected to write additional back ends for their specific needs.
LVQ學(xué)習(xí)矢量化算法源程序
This directory contains code implementing the Learning vector quantization
network. Source code may be found in LVQ.CPP. Sample training data is found
in LVQ1.PAT. Sample test data is found in LVQTEST1.TST and LVQTEST2.TST. The
LVQ program accepts input consisting of vectors and calculates the LVQ
network weights. If a test set is specified, the winning neuron (class) for
each neuron is identified and the Euclidean distance between the pattern and
each neuron is reported. Output is directed to the screen.
This project is created using the Keil ARM CA Compiler.
The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM Output signal on PORT3.0 and PORT3.1
This ARM Example may be debugged using only the uVision Simulator and your PC--no additional hardware or evaluation boards are required. The Simulator provides cycle-accurate simulation of all on-chip peripherals of the ADuC7000 device series.
You may create various input signals like digital pulses, sine waves, sawtooth waves, and square waves using signal functions which you write in C. Signal functions run in the background in the simulator within timing constraints you configure. In this example, several signal functions are defined in the included Startup_SIM.INI file.
This example program shows how to configure and use the A/D Converter of the following microcontroller:
STMicroelectronics ST10F166
After configuring the A/D, the program reads the A/D result and Outputs the converted value using the serial port.
To run this program...
Build the project (Project Menu, Build Target)
Start the debugger (Debug Menu, Start/Stop Debug Session)
View the Serial Window (View Menu, Serial Window #1)
View the A/D converter peripheral (Peripheral Menu, A/D Converter)
Run the program (Debug Menu, Go)
A debug script (debug.ini) creates buttons that set different analog values in A/D channels. As the program runs, you will see the A/D input and Output change.
Other buttons create signals that generate sine wave or sawtooth patterns as analog inputs. µ Vision3 users may enable the built-in Logic Analyzer to view, measure and compare these input signals graphically.
This directory contains the memtest 8051 firmware
for the Anchor Chips EZ-USB chip.
The purpose of this software is to test the different
memory segments in the Ez-Usb chip.
This example will Output the string "good" on the 7 segment
LED if the mem test passes, or it will Output the first address
where the memtest fails.

The LT® 1529/LT1529-3.3/LT1529-5 are 3A low dropout
regulators with micropower quiescent current and shutdown.
The devices are capable of supplying 3A of Output
current with a dropout voltage of 0.6V. Designed for use
in battery-powered systems, the low quiescent current,
50mA operating and 16mA in shutdown, make them an
ideal choice. The quiescent current is well controlled it
does not rise in dropout as it does with many other low
dropout PNP regulators.
