This is my eleventh week in AESTE. This week my task is to download a file from the network. There are a lot of protocols can be used to download the file via network. At the end we choose TFTP(Trivial File Transfer Protocol) due to TFTP will transfer maximum 512 bytes data. It will be easier for us to store the data to flash memory (flash memory write by WORD,QWORD, ROW and PAGE). After I had studied the concept of Read more
Here we go again. In the previous chapters, I have mostly done the management of multiple cloud storage services in the application. For this chapter, I worked on setting up the layout and the displaying of projects on the dashboard interface. You have already seen a small portion of it in the last chapter, where there is a large view showing the snapshot of a project that the user would open for viewing, and the meta data related to the Read more
The following is the simplified design flow for digital circuits. Design Entry Behavioral Simulation Synthesis Functional Simulation Place and Route Timing Simulation Implementation Synthesis is the process of turning the HDL code into circuitry. A software analogy for this is the compilation process that turns software code into machine binary. It is one part of the overall hardware design flow. Behavioral simulation is mostly concerned with how the hardware is supposed to work. At this stage, there isn’t any circuit Read more
The purpose of a checksum is to determine whether a message was transmitted error free. There are many ways to determine a checksum and one of the ways to do this is to use a cryptographic hash. A cryptographic hash function has several useful properties to do this: A single bit change in the input produces a radical change in the output hash value. This means that even a small error in the input will result in a completely different Read more
I’m struggling to finish up the head judge screen this week and I’m facing few problems as well. I managed to assemble necessary information such as absolute score, comparative score and each judge’s scores for the screen At first, I’m having a problem to display scores on the screen because I wanted the scores to be displayed in progress circular with color according to gsb function and having tooltip function as well showing scores if the performance is multi-piece performance.

This is my tenth week work in AESTE. This week I had successfully to test the Bootloader Live Update work. Although it is update by USB device (my actual project use Ethernet). But that is a good starting point, at least I know how to use the live update demo from Harmony. Next step I have to do are: Upload a file to localhost by TFTP. PIC32MZ get the file from localhost by Ethernet. Using PIC32MZ check the file is Read more
Hello again. Welcome to the second chapter of my series of developing the frontend of my current project using Vue.js and Vuetify mainly. This week, I continued working on the storage aspect of the dashboard application. I had already made an interface for storage configuration, now I would just need to display the list of configured storage to the user and also enable them to add and configure more storage services on demand. Apart from that, I also set up Read more
Submit Score I had difficulty when I tried to add submit score functionality on the judging screen. I kept getting an error when I tried to submit the score for each performance. The parameters that need to be sent are performance Id, judging Id, absolute, scores and comparative. At first, the system gave me an error because I didn’t put the scores as a parameter. Secondly, I didn’t put the comparative as the parameter since I’m not doing the comparative part Read more
This is my ninth week in AESTE. I spent almost my whole week to study the theory of bootlaoder and how the dual memory work for PIC32MZ. Only the PIC32MZ has dual memory bank, other PIC32 only has one. Bootloader is used to upgrade the firmware of microcontroller without using any external programmer or debugger such as PICkit 3. Harmony provides two ways to implement this, one is basic method (all PIC32 can use this) and another is live update Read more
From here on, I would be writing a series of blogs conveying my trials and experiences developing for the frontend of my current project using Vue.js. The title of my blog posts after this one would follow a similar pattern to the one above, partly because I’m running out of blog posts titles ideas as well. Let’s get started then. Last week, I talked about making some changes to the backend of the application, given our new way of dealing Read more
