| Increase microcontroller code efficiency | | 2008-03-09 07:36:53 | | C compilers are getting more and more advanced, but there is always a trade off made between speed and code size. Compiled code can be faster or smaller but not both. So you have to choose which part is more important speed or code size.The Increase of microcontroller code efficiency can be done in many […] | | By: born4electronics1 | | |

| Minimizing microcontroller code size | | 2008-03-09 07:36:29 | | Reducing microcontroller code size isn’t ease task, but what if you want resulting code to fit your available memory…Minimizing microcontroller code size can be done in two ways:Firs is using compilers optimization feature by code size. This optimization is very dangerous. Your optimized code may not work as supposed to because compiler may eliminate some […] | | By: born4electronics1 | | |

| Microcontroller eats too much of RAM | | 2008-03-09 07:36:03 | | All you know that microcontrollers have limited amount RAM and EEPROM. For instance ATMega128 has 4-Kbytes of RAM, 4-Kbyte of EEPROM. This may seem quite enough for some applications, but more complicated routines require more of RAM. And there is no compiler that can do better optimization on usage of ram than programmer.The main aim […] | | By: born4electronics1 | | |

| PIC Microcontroller Spud Gun | | 2007-06-06 14:31:35 | |
This PIC Microcontroller Spud Gun looks to be well built and constructed. The PIC controller allows for lots of safety features such as only allowing a single charge of fuel and ensuring that there is a projectile in place before fuel can be introduced. Watch the video to the end to see a ball get fired.
“This project is definitely not small potatoes — three barrels loaded with spuds and charged with propane! Two PIC microcontrollers handle the User Interface, Azimuth and Elevation Aiming and Fire Control functions. Aiming is controlled with a joystick. The Fire Control subsystem verifies a projectile is loaded in the selected barrel before injecting the controlled charge of fuel and that the barrel is armed before firing.”

| Gesture Controlled Lamps using the Arduino Microcontroller | | 2007-06-05 13:04:37 | |
These Gesture Controlled Lamps use the Arduino Microcontroller to detect movement and adjust the lights accordingly. If you want to get your hands on a free Arduino microcontroller have a look at the latest uC Hobby giveaway.
“Gestures in front of any lamp affect all the lamps. The lamps all show the same display, but it depends on which lamp generated the triggering event.
For those of you new to the project: the concept is “action at a distance”, the lamps all react in unison regardless of distance (well, within a few hundred meters). Technically, quite complex: uses AD5206 digipots, Zigbee radios and Arduino minis, all held together with some elaborate software.”

| Autonomous Blimp - ECE 476 Microcontroller Design Project | | 2007-06-01 19:01:42 | |
Benjamin Tang and Rishi Ramchand are Cornell University students who made an Autonomous Blimp as their final project in the ECE 476 Microcontroller Design course. The project uses a GP2Y0D340 IR sensor to see if there is an obstacle in the way that needs to be maneuvered around. That IR sensor looks to be the type that is normally found in the automatic water taps that are found in most modern commercial bathrooms, with a 2 foot range I can think of lots of cool uses for the device…
“Our project controls a propeller-driven toy blimp; it keeps the blimp moving in a straight line if its path is clear, and otherwise navigates it around obstacles in its path. To accomplish the former task, our circuit uses a gyroscope to detect horizontal rotation and compensates for it by adjusting the propeller speed. Obstacle detection is performed using a digital infrared proximity sensor. The central challenge of our project was to build a circuit that was sufficiently light to be | | By: Hacked Gadgets | | |

| Automated Microcontroller Programmer | | 2007-05-27 13:15:35 | |
ASTLAB has built an machine that automates programming microcontrollers. This could be a useful machine if you needed to make hundreds of pre-programmed microcontrollers. There is a tube of blank microcontroller chips on the right, and the programmed ones on the left. A motorized arm moves over to this tube and grabs a blank chip using a suction tool and drops it into a ZIF socket, a servo then closes the ZIF socket allowing the chip to be programmed. The arm then picks up the programmed chip and drops it into the tube of programmed chips.
It looks like the project is well documented, unfortunately I don’t understand the language and my trusty Google translator doesn’t help either. If someone wants to summarize it in English I would be appreciative.

| Microcontroller Project Information | | 2007-05-24 20:39:58 | |
Ross Smith from the University of South Australia gave an interesting microcontroller design presentation that contains some useful information for anyone that is considering using one in their next project.
“This presentation looks at how to develop your own custom microcontroller hardware from scratch. Often laptops and general purpose computers are too powerful and too large to use for simple hardware projects. Often you can perform tasks like controlling DC motors, stepper motors, switches, LCDs, LEDs, buzzers/speakers etc. efficiently and effectively using inexpensive/free microcontrollers. Other benefits such as extremely small size and ultra low power consumption are also inherent benefits of most popular microcontrollers.”

| Microcontroller Simulators and emulators | | 2007-05-18 17:07:03 | | Sometimes you just haven’t ability to flash microcontroller in order to test program functionality in development phase. For this there may be many reasons like you don’t have a prototype ready or you need to test parts of code and so on. For this there are software simulators used which simulates microcontroller work without microcontroller itself. Simulators usually don’t have connection to real world all operations are simulated in software. Microcontroller simulator is a program model which imitates its work. Modern simulators now simulates not only arithmetic operations but also I/O operations and even peripherals like timers, ADC, USART, I2C and so on. In many cases there is possible to prepare whole project jus using simulator and then burn compiled code to real microcontroller.
Simulators usually allow:
debugging at source code level;
follow operation time in slow motion but with real world values;
connect stimulus signals like they are real world sign | | By: Scienceprog - Embedded Related Info | | |

| Microcontroller to SMS Interface | | 2007-05-07 16:39:19 | |
In the microcontroller world some things are a bit tricky to do without some help. This can be some code libraries that help us talk to an LCD display, or communicate via some of the new serial protocols such as one wire. Elektronika.ba has done some work to help everyone out who wants to interface a microcontroller to a GSM phone. Thanks for making the English version for us. Code and diagrams are available on his site.
“This device acts as interface between your microcontroller project and a GSM phone. It handles all modem data communication between the GSM phone and your micro-project. The best thing is that it decodes PDU into TEXT on the fly!
It’s based on PIC16F877A microcontroller running on 16MHz at 5V. It has an onboard level converter for serial communication with the gsm phone because PIC’s UART RX input pin has a Schmitt trigger triggering at 4,5 - 5V while the phone is sending only approx. 3V from it’s TX pin. It also has a zener diode at TX p | | By: Hacked Gadgets | | |
