DIY USB Oscilloscope using a dsPIC

Intro The main purpose of this article is to create a crude, PC-based oscilloscope. A dsPIC33 is used to take ADC samples of an external signal. The data is sent to a PC via a serial-to-usb converter. The PC runs a custom C# program that displays the waveform. The slope and trigger can be adjusted through the PC app. The PIC microcontroller's ADC....... Read More

PIC microcontroller bluetooth example with an Android phone

This tutorial will cover setting up the HC-06 bluetooth device with a PIC microcontroller for Bi-directional data between the PIC and an Android phone. I will be using a PIC16F1829 in a PDIP package, which comes with the PICkit 3 Low Pin Count Demo Board or the PICkit 3 Starter Kit. You don't necessarily have to use this exact microcontroller. The....... Read More

HD44780 LCD Driver for a PIC

The post will utilize the popular Hitachi HD44780 16x2 Character LCD (sometimes mispelled HD47780) to print simple messages from an 8-bit PIC. I will be using the PIC16F1829 to write to the LCD in 4-bit mode (only 4 pins). The PIC16F1829 comes with the PICkit 3 Low Pin Count Demo Board or the PICkit 3 Starter Kit. Microchip's starter kit hardware....... Read More

If you don't know how to use Proteus and MikroC , don't worry - I'm going to show you everything step by step. First you need to download two essential softwa....... Read More

Getting Started Arduino

Introduction The Arduino is a single board microcontroller that can be programmed to process inputs and outputs from different components externally connected to its GPIO's (general purpose input output).In laymen's term Arduino is a small computer that can be used to calculate and process data from different sensors connected to its inputs and th.......

MSP4340 LaunchPad - Simple UART Config and Echo

The Universal asynchronous Receive/Transmit (UART) is a vital communication protocol that is relatively easy to setup and use. It can be coded strictly in software using general purpose I/O pins, commonly referred to as bit-banged, or it can be implemented in hardware. The advantage of using the all hardware approach is that is frees the CPU to ex....... Read More

MSP430 Launchpad - Blinking your First LED

This post covers how to quickly get started using the MSP430 Launchpad. There are several variations of the Launchpad now circulating ever since its launch in 2010. I will be using the popular MSP430G2552, which is usually categorized under the MSP430G2XX series. You can easily start playing with one of these at a nearby hackerspace or on digikey.......
