Rickey's World of MicroControllers


Hello everyone,
Welcome to Rickey's world of Microcontrollers and Microprocessors. Here you will find everything related to microcontrollers, you can download codes, libraries, examples, discuss about your projects and ask doubts in the forum.

I put my all effort in providing all students and embedded developers to find what they are looking for. I am constantly updating this website so that all most commonly used microcontrollers (i.e. 8051, PIC, AVR, ARM etc..) resources can be made available on this website.

In the download section you can find Microcontroller projects on 8051, PIC and AVR. if you want to contribute this please mail me anytime at contact[at]rickeyworld[dot]info, send me the details and files of the project you made. I will post that project in my website.

8051 Microcontroller News PIC Basic Project: Graphic Thermometer Recorder
By Ajay - Monday 30 June 2008 - 07:26:07 in Rickey's World News

PIC Basic Project: Graphical temperature recorder (16F628 + LCD Nokia 3310 + DS18B20)

Gioppy wrote ...
Here a nice graphic temperature recorder.

Features
It shows 60 samples. (new values scrolls left the plot)
Temperature is sampled every 15 Sec. and averaged.

The following parameters are configurable.
Sampling rate 15 Sec. to 3.825 Sec.(255*15)
Initial scale -30°C to 90°C
Scale resolution 1°C to 20°C division
Display contrast level

Configuration parameters are stored in eeprom.
To change parameter only the eeprom must be reprogrammed (NOT the code)
Refer to source code to know where they are stored.
N.B. Negative temperature for the initial scale value must be stored in 2 compliment form.

Source code attached.
(sorry for the Italian comment in the code, i have not time to translate)
Regards
Gianni

8051 Microcontroller News New AVR Project
By Ajay - Thursday 12 June 2008 - 00:03:49 in Rickey's World News

DDS Audio Function Generator - Bascom AVR Project

Gioppy from Italy mailed me this new Bascom AVR project. Its an Audio function generator with lots of features like:

  • DC/AC Output selection
  • Type of Output signal selection
  • Wide range of frequency selection

This is what he mailed me about this project
Gioppy wrote ...
Bascom-Avr Compiler

ATMEGA48 DDS Audio Function Generator


Features
Frequency range : 1Hz - 20KHz useful to 100KHz
Resolution : 1Hz
Waveform : Sine, Square, Triangle, Sawtooth
Output level : Adjustable 0 - 5V.p.p.
Square wave open drain output (TTL compatible)
Battery powered

I don\'t recommend this project for anyone who is NEW to electronics.

--------------------------------
ATMEGA48 Fuses configuration:
Spien ON ,Rstdisab OFF, Esave OFF, Ckout OFF, Wdton OFF, Ckdiv OFF,
SelfprgEn OFF, DwEn OFF, Bodlevel = 111 , Cksel = 0111 , Sut = 11
--------------------------------
