PIC Microcontroller

These are Tiny Chips that integrate the Microprocessor and Peripheral chips in a compact size with low power consumption. PIC Microcontrollers from Microchip are the evolved computing digital devices that go into many gadgets and intelligent equipment. These ar easy to program and reprogram and even protect your code or IP.

The PIC has the math power. The memory, the I/O ports are integrated in the chip like 8051. Some may remember that Microprocessors like 8085 and Z80 had all these functions in chips outside and used to consume more power. Then came CMOS and better IC technology. The 8051(now avr, atmega)and PIC Micro are entire boards in one chip.

PICkit 1 Flash Starter Kit of Microchip

The PICkit 1 FLASH Starter Kit is a low-cost development kit with an easy to use interface for programming Microchip's 8/14-pin FLASH family of microcontrollers. This starter kit is designed to help the user get up to speed quickly using PIC microcontrollers.

USB Serial Interface

There are many Serial Data Devices that means those that use the RS232 (old mouse port). USB is now the standard interface in most computers and embedded devices. Many mini embedded sensors and devices come with High Speed Serial Interfaces.

This page lists solutions and methods to get These Devices talking with your computer. The focus will be HandHeld Computers made of the Android OS. This way you can get your hand on the Real World thru USB and Serial. USB to parallel also helps when you want to control a Relay or Solenoid Array. Wireless Interfaces also are a good Solution with Networking.

USB TTL Serial Cables

The USB TTL Serial cables are a range of USB to serial converter cables which provide connectivity between USB and serial UART interfaces. A range of cables are available offering connectivity at 5V, 3.3V or user specified signal levels with various connector interfaces.

Embedded Systems Design

An Embedded Microcontroller or DSP system is made of Chips, Circuits and Firmware. The digital voltage levels, speed, bus width, fan out, power consumption are some factors that a designer has to keep in mind. As portable and wireless gadgets are becoming more popular, RF, Ethernet and Energy Efficient Design aspects should be studied. Power electronics and Analog Circuits knowledge is used around the system, all this is integrated to make an instrument, equipment or gadget.

Accelerometers and Gyroscopes

The ADXL345 from Analog Devices is a small, thin, low power, 3-axis accelerometer with high resolution 13-bit measurement at up to ±16 g.

Ben's HobbyCorner - Software - Bascom-examples On the right the ADXL345, connected to the I2c-bus, and when connected well, you will find it in the I2c-scanner. This is the Bascom-AVR code for the I2c-scanner. When the ADXL345 and the HMC5843 are fixed on the board you should see this in Hyperterminal.

Power Quality and Clean Energy

"Earth leakage currents arise mainly from the EMC filters built into electronic equipment with switched mode power supplies. Standards limit the leakage current from non-fixed equipment (i.e. equipment that plugs into a standard socket outlet) to less than 3.5 mA. When a lot of electronic equipment is in use, the total leakage current in the protective conductor can become significant."

SoC the System on Chip and IP

When a product has to be made small, the board real estate is limited or it has to be manufactured in large numbers.... SoC is the Answer. A Microprocessor evolved into a Microcontroller by packing many external chips into one chip. Now uC Card along with the other blocks like A-D, Port Drivers, Networking elements, Display Driver and other peripherals can be packed into one chip.

Some Power Supply and RF blocks cannot be easily added inside as they have a silicon processing more specific to their applications. Laser trimmed Instrumentation Op-Amps, high accuracy resistor arrays, high value capacitors, magnetics and supporting chips are placed outside on the PCB.

The SOC can pack Digital Chips, Memory, A/D, D/A converters, uC, RAM and Custom programmable areas. For more specialized communications, analog and power requirements; Special SoC types can tackle RF and Power management within a chip because of proprietary silicon processing expertise.

Serial Port and Terminal Emulation

When you wish to Interface an Embedded System to your computer, you will need a Terminal Emulation Software to communicate with the device over the serial port. Now USB is the default port in most computers. Hence we have USB to serial Interfaces. Over this Interface Data and Firmware can be Transferred up and down. 

Termite is an easy to use and easy to configure RS232 terminal. It uses an interface similar to that of "messenger" or "chat" programs, with a large window that contains all received data and an edit line for typing in strings to transmit.

Termite Terminal - RS232 Interfacing - CompuPhase

Plug-in interface for pre-processing or alternative views of the data, logging received data to a file, adding a toolbar to Termite, and other functionality that you may think of.
