Creating my own TV Tuner IR remote with a PIC16F684

by Tahmid on 9th February 2016 at 02:43

While I was home this winter, I saw that the remote for our TV tuner was damaged physically, causing the buttons to not function responsively. Some of them just didn't work. I saw this as an opportunity for a fun couple days' project to build a new remote controller for the tuner.

The TV tuner was manufactured by a brand name RealView and, as expected, I couldn't find much detail

Using input devices on Embedded Linux: An example with USB mouse on the Intel Edison

by Tahmid on 28th December 2015 at 14:53

The Intel Edison test board, along with the USB mouse

I have recently been using the Intel Edison for the Cornell robotics project team (which co-hosts the Intel-Cornell Cup USA competition). Building on my previous knowledge of embedded systems, I started learning to use and program on Linux. The distro used is Yocto (all information is available on the Intel Edison website).

Stereo audio player using the PIC32, MCP4822, microSD card and the MDDFS library

by Tahmid on 10th January 2015 at 22:22
Using the PIC32MX250F128B, I decided to make a simple audio player. I wanted to play back good quality audio from a large memory space - a microSD card. So, I made this WAV player that can play back 16-bit 44.1kHz WAV files with 12-bit stereo audio output. Of course that's not all it can play back. It is programmed for automatic period configuration so that the period is set on the fly based on the song sample rate. It can play back both 8-bit and 16-bit mono and stereo audio files and I have tested

Modalities of Using the PIC (16F877A) CCP Module - Compare Section

by Tahmid on 7th December 2012 at 18:02
Here I will show you how to use the compare section of the CCP (Compare, Capture, Pulse Width Modulation) module of the PIC16F877A. You can use this concept for any PIC with a CCP/ECCP module.

There are 2 modules associated with the compare section – the CCP module which we’ll use for the compare function, and the Timer 1 module. The function of the compare module is to compare (obviously, as the name suggests) the value of the CCPR1 register against the Timer 1 value. The CCPR1

MAGIC of knowledge

by Tahmid on 22nd November 2012 at 20:47
I turned the switch on and BOOM! That noise, the tiny puff of smoke and the accompanying smell had become far too familiar.

I looked on in confusion at all the failed electronics components in front of me. I needed answers. Why did the H-bridge circuit not work as “claimed”? Books showed numerous such circuits. The Internet was not short of designs either. They were all similar though. I had done my research. I thought I understood the principles and modalities of operation. Then,
