Flash & Bitstream

I started off this week by troubleshooting and testing the flash functions. In harmony there are two non-volatile memory drivers, NVM and Flash. Usage of the flash driver is simpler compared to NVM. The functions allow you to write a word, quad word, or a defined row size. Though you must handle bit-shifting when writing large data. You’ll find how the functions work in this documentation. After I’ve verified its functionality I attempted to test it by writing a dummy key for the Read more

Debouncing

Bouncing is the likelihood of metals to come into contact with each other, when the contact is opened or closed, producing unwanted multiple signals. Debouncing is the method of making sure only one desired signal is produced based on a single opening or closing of a contact. I have proceeded with the next module, push button. Dr. Shawn said that it required a debouncer since the push button has the tendency to bounce. I find it interesting learning how debouncing Read more

The flow

This week was mainly spent finishing up the flow of the program. I first started with modifying the data file importer to accommodate the requested changes and continued with the addition of the CRUD functionalities of the admin page. I then started work on the MC page to handle the entire event. This mainly involved handling the logic on the flow of the program and how the various roles interact with each other. Then followed some automation of the process Read more

Second Week of Internship

For this week my progress is still slow. I continued my study about CakePHP and at the same time I  tried my best to understand the structure of the first project that Dr.Shawn gave me.  I also do some study about PHP just to recall back what I have learned in university. On the last day of the week, I met Dr.Shawn and he gave tasks to me which I need to fix two bugs in the website. He explained Read more

Code Translation and JointJS

I work on generating Verilog version of source code based on user input which is coded in C++ this week. I study Verilog-mode and the way of this tool functions to properly instantiate the signals’ name. I make sure the program labels each device respectively to user’s input while doing the translation from C++ to Verilog in order to organize the system and it also helps when I need to come out with a naming convention for the connection between Read more

PIC32 HMAC-MD5

I spent this week jumping between tasks as I tend to get bored working on the same thing for long. This week I worked on implementing HOTP, flash and troubleshooting the SSL server. HOTP works by computing an HMAC based on 1- A static secret key generated by the server and known by the client. 2- A changing factor which is a simple counter. The server remembers the last value of the counter for which a correct password was entered. If the user’s Read more

What Happiness Sounds Like…

My work on the passive buzzer had entered its 4th week. I did not like that 4 weeks means a month. When days become weeks, and weeks become a month, you know your work performance is not doing good and you need to do something about it. I wish I was able to do it on my own but at the end I still needed help from Dr. Shawn to finish. Dr. Shawn checked my codes and asked me to Read more

Sending & Writing The Bitstream

Eighth week. Slow. I did not manage to implement HOTP nor SSL. My cryptography knowledge is weak. I had a ton of studying to do and even more still. As for SSL, with some slight troubleshooting it should work soon, but its not a priority at the moment. Flash code is also not finished and for what I’ve written I haven’t confirmed the functionality. I found out I was not receiving and writing the bitstream properly over the network and onto the FPGA. I Read more

First Week in Aeste

On the first day, another intern and I met Dr. Shawn in the office. He directed us to setup some tools for the office usage and he also gave us a talk about the concept of gitflow. Just like every other intern, Dr. Shawn treated us a lunch at the mall nearby. We had a good talk during the lunch and he briefly told us about what we will be working on for the next few months separately. For the Read more

Backtracking

For the most part of the week everything was going according to plan. Setting priorities right, we decided to focus on the flow of the application which meant making sure that the application is ready to be used by the end-user with its core functionality done. So far, the Poco library for encrypting autologin links, score sorting features, redirection for login links and the some parts of the admin page were all done. I then met with Dr. Shawn during Read more
