Demosaic Core on Zedboard

Finally, after weeks of working on the demosaic core on software simulation, the real hardware implementation starts! The week went with the couple of frustrations on debugging the Xilinx PlanAhead tool, and the excitement on implementation of demosaic core on FPGA. 😆 😆 😆 Using Zedboard to Test the Core This is the first time I use an FPGA, and it came across to be the powerful Zedboard. Although I had some hard time learning to use it at first, but later I found Read more…

Shooting Troubles #3

Continue from the previous blogs, this blog focus on debugging the upcoming errors that may be faced on while using the Zedboard. These errors are the bugs from the Xilinx PlanAhead 14.4, 2012 late version, working on Ubuntu 14.4 operating system. XPSGuiSessionLock Error Initially, I was following the Zedboard CTT ISE 14.4 tutorial from the official Zedboard website, and I found that the tutorial is not working fine for me. The annoying error of XPS about the XPSGuiSessionLock, actually put a hold Read more…

PIC32MZ PPS feature

This is my thirteen week in AESTE. Getting closer and closer to the end of my internship~  This week I continue with drawing Schematic. 😴 💤 💩 😈 👿 👹 👺 💀 👻 👽 🙌 👏 👋 👍 👊 ✊ ✌️ 👌 ✋ 💪 🙏 ☝️ 👆 👇 👈 👉 Nothing much to share about because its just drawing PCB based on past interns’ work and this link. Drawing schematic is really easy and straight forward. I am using KiCAD for Read more…

Combination Demosaic Algorithms

Finally, this week I finished on the schematic of the whole demosaic core, described it in Verilog, and simulated it using the Icarus Verilog simulator. In the path of implementation, many problems occurs and it was really interesting to tackle them. The Edge of Bilinear Interpolation Bilinear interpolation is a simple and easy method to interpolate the Bayer pixel, which uses side (neighbor) pixels to perform the interpolation. Initially, I was planning to build it with a switching in interpolation algorithm Read more…

Wt: A Project Manager

For the whole week, I’ve been continuing work on my task, which is to build some sort of project manager interface. Last week, I built a simple interface without much functions. So, what I did is mostly creating functions and improving the graphical interface. Requests, requests and more requests As I am working with Google Drive to handle project files (store/delete/upload/download/modify), I need to constantly send requests. In default use, my app is given only project folder access, which means Read more…

Wt: Response Header from Server

This is my twelve week in AESTE. Continue fixing some minor bugs for my JQuery with Wt and many studying and planning for my PCB design. Getting Started with having SERVER sending request to CLIENT First I change my ‘CUSTOM’ request into ‘HEAD’ request, and have my SERVER (PIC32 in this case) able to send a header to my CLIENT (Wt in this case). The concept is really simple and the method to achieve it is also very easy, however Read more…

JQuery with Wt

This is my eleventh in AESTE. Trying to use Witty (Wt) as a CLIENT to send request to my PIC32 wolfSSL server. My time limit is 3days to get this done.      ̿̿ ̿̿ ̿̿ ̿̿ ̿’̿’\̵͇̿̿\з=( ͡° ͜ʖ ͡°)=ε/̵͇̿̿/’̿’̿ ̿ ̿̿ ̿̿ ̿̿                                                                             Read more…

Boundary Bilinear Interpolation

This week, things are getting clearer, and the work are getting better. I began to realize my previous mistake, that the image processing pipeline core might be driven in different clock speed, compared to the CCD clock speed. The core should be able to drive as close as the CCD clock speed, as this will produce a low power design. The Boundary Bilinear Interpolation As I finished the circuitry of the High-Quality Linear Interpolation, and tested it with Icarus simulator, Read more…

User Authentication with Wt

This week, Dr. Shawn gave me a briefing on my new project. It seems quite a hefty task for me, but I hope I can finish it in time. FYI, I am working on a some sort of online project manager with user identification. The first thing I started working on is using the built-in GoogleService and FacebookService under Wt/Auth Class. Trying out the OAuth Example in Wt In short, the authentication services did not work. After pressing the logo Read more…

And Over the Finish Line

My 12 weeks of internship has finally come to an end. This journey has been bitter sweet with lots of lost hopes and high expectation, with tears and joy and cries of frustration. But beyond all that, I have created something significant. Maybe in comparison it might not be a lot but from where I received my project and the minimum knowledge I had initially, I managed to authenticate Dropbox’s user accounts, upload, download and delete files, store user info Read more…
