Get started with Microcontroller | Atmega328p


For those who are new to microcontroller, microcontroller is nothing but a mini computer within a chip. It has ram, a processing unit and all those needed for a computer to work. But in a mini scale. You can program your chip with a burner circuit.
You need a software like avr studio to compile the program. Then you need a software like SinaProg to put this compiled HEX program to your chip. I use a USBasp ISP as the burner. You can buy that from www.electroncomponents.com. For the rest of the post I use Atmega328p microcontroller. Have been playing with atmega328p avr microcontroller for sometime. It’s a High Performance, Low Power AVR® 8-Bit Microcontroller with 20Mhz speed. There won’t be much difference with other avr series microcontrollers except the no. of I/O ports, ADC, speed etc..
I would recommend avr studio 6 for compiling your program. First of all it’s free. It’s based on Microsoft visual basic platform. If you are a beginner it will be very helpful as it has code prediction. You can use any flashing software. I am using SinaProg.

(NB:If you plan to buy it, you need to manually change the order of connecting the wire. The RES, MISO and MOSI pin are aligned miss correctly. Just crack the female berg connecter and put it correctly. Otherwise you can’t program the IC. USB A to B cable is included. You can also burn 8051 family microcontroller using this programmer.)

Plymouth theme for Ubuntu

Bored of having the same boot animation screen again and again? There are plenty of Plymouth themes available out there. This is a theme I created by slicing some cool gif files I found online. You can download the theme and find the installation steps on my github account. ( https://github.com/krishnan793/PlymouthTheme-Cat )  The theme is created for Ubuntu 16.04. But this can be installed on previous versions with slight modification. If you have a slow computer then you can watch the whole animation loops. (The VM I used to record the screen was fast though. :))

Getting started with GPIO (Testing GPIO with a multimeter)

There are 65 possible GPIO pins that you can control. Some of the GPIO pins are normally configured to different functions. Let's play with one of them. Go to the beaglebone website and figure out the header pin corresponding to gpio23. The gpio23 is mapped to the 13th header pin. In this tutorial we are testing the gpio23 output using a multimeter (Do not connect an LED directly to BBB IO pin). First go to following directory cd /sys/class/gpio / Then make gpio23 available echo 23 > export A new directory will be created. Open gpio directory. cd gpio23 The direction of IO will be normally set as in (input).  To make it as output, echo out > direction Then set the pin to high using echo 1 > value Measure the voltage at pin 13 of P8 header. If its 3.3 V then you are on the right track. Pin 1 and 2 will be ground. You can connect the negative terminal of multimeter to pin 1 or 2. To set output as zero, echo 0 > value After finished wit...

Remote access your BeagleBone Black using vnc

Before going into how to share desktop with your BBB I assume you have a proper ssh access to your BBB. (through USB) (if not read this ) Also this tutorial is for BBB with Debian installed (type cat /etc/*-release to know which distro you are currently using. Or refer here ) First install the vnc server in BBB.(After logging into BBB) ssh root@192.168.7.2 apt-get install x11vnc Then go to your local computer and open a terminal window. Install a vnc viewer like vinagre. sudo apt-get install vinagre Now its time to start vnc server in BBB. x11vnc -auth /var/run/lightdm/root/:0 -forever This will start a vnc server at port 5900. Note this server setup is temporary. If you want to remotely connect to your BBB after a reboot type the above command again. Go to your local computer and type  vinagre 192.168.7.2::5900 A remote desktop will be shown if all goes well. Try exploring other options in x11vnc using (in BBB) man x11vnc Th...
