Flexibility in Naming

This week, I made a documentation about naming convention. I learned the importance of documentation and communication because it ensures a smooth workflow of project and it helps someone in the future to understand the concept quickly and continue working on it. Other than that, I study wishbone and learn about the signal between Master and Slave. I find out that signals named ‘stb’, and ‘cyc’ control the timing to latch data. I can manipulate these signals to activate different Read more

Half Done

At the beginning of this week, I realized I had only another month of internship to go which made me feel bad over the fact that I was not done with at least half of the sensors. I was determined to be as fast as I can in finishing them. I referred to Dr. Shawn regarding the widths of the debouncer design and showed how I had to change few lines of codes that is dependent on the widths of Read more

Working on the Query Builder

After doing some reading I managed to find the right SQL. I tested it on PostgreSQL first because that’s how Dr Shawn taught me. He told me before I start working on something I need to know what I want then it will be easy for me to follow the right path. Otherwise all the things that I do will be useless. Next, I have to work with Query Builder in CakePHP. I have to find the right query and Read more

Relief

This week did not start off well. Despite spending the weekend trying to get the application to work on the Pi, it still kept on crashing in most parts of the application. This was getting frustrating as it was working on both my computer and the work computers but failed at the actual deployment environment in which we were going to run the application on. When I showed the application to Dr. Shawn on Monday, he noticed that it was Read more

PIC32 TCP Performance & The End

I spent this week measuring the TCP performance of the CORS program. We wanted to know how fast can the board actually perform from a network perspective. I collected data on multiple parameters that I’ve determined to have a considerable impact on speed. I was appalled to find out that the PIC32 was reading data from the network at around 560 Kbit/sec, and after testing, I managed to improve it to 30 Mbit/sec. For my trials I used iperf and Read more

First week in Aeste

On my first day of internship, Dr Shawn talked me through a git branching model and I proceed to study more on Git for the rest of the day. Then, I spent the following two days studying witty and web application. On the fourth day, Dr Shawn came to the office. After reading through the codes written by the previous interns, Dr Shawn explained the simulator project to me in detail. On the fifth day, I studied about web application Read more

Input Characteristics Determine Debounce Time

After much reading and some calculations, I learnt that theoretically the ideal bits of the LFSR counter in my design should result in the range of 300 µs to 5 ms debounce time. The width had to be quite large since the FPGA board clock speed was 100 MHz. For validation of the specific time to be put in the design, I tested the push button with a range of LFSR widths. I started with low widths that gives about Read more

The Bug Hunt

With the deadline approaching, I spent the last week making sure that the application is accessible and user-friendly enough for the end user. This was mainly accomplished with the use of CSS. With that done, I continued with deploying the program on the tablets. However, there was an issue with the browser rendering the overflowed portion of a page black when accessed in full screen mode. There was also what initially thought to be a problem with logging in into Read more

Enlightenment

This makes my 11th week with Aeste. I started off by implementing the generation of the RNG key which is to be read from the flash and performing even more trials to make sure it works exactly the way I believed it did, which Dr. Shawn stressed. Because most interns including myself half-ass everything 90% of the time, and the code is just yolo. I believe my half-assed implementation worked, but the Flash and FPGA libraries were still full of flaws, and Dr. Shawn notified me Read more

PostgreSQL

I start this week by working with PostgreSQL which is a new thing for me. I have to learn how to use it first before I start.  So basically this week I try to familiarize myself with PostgreSQL and doing some SQL commands to solve fix the bug. But in the end of this week I just realized that I have misunderstood Dr Shawn’s instructions and the way I use PostgreSQL was wrong because I was not using the development Read more
