This week was an intense week. The week started with me demonstrating the modem to Dr. Shawn and with a short check of the modem’s code by him. He noticed that there was no obvious state machine in the code which prompted a rewrite of the code to include one. From that, I spent a day or two rewriting the code to incorporate the state machine and also the buffered commands that was required for a typical modem. Dr. Shawn Read more
This week I only worked for two days as I took leave for three days so I do not have much progress with my project. I met Dr Shawn on the last day of the week and I showed him all the works that I have done so far. When Dr Shawn saw it, he realized that there are a lot problems that need to be fix on front end. He explained to me things that I have to do Read more
This week, I finished a working version of the modem which now supports sending data and properly detecting when there is a disconnect to allow reconnecting properly. There are however, a few limitations as of now. One of them is that for some reason on the current firmware, I am unable to use more than 3 concurrent sockets. And to make matters worse, the TCPIP_TCP_ServerOpen function that was included in the TCP-IP Library in Harmony v1.11 crashes the firmware when Read more
This week we tried our best to finish and build all the features that are needed in project manager front end because the intern that work on the back end finished his internship this week. So we work together to build the download button, Edit and Create features in the project manager. These features were quite hard to do because we have to do customization and to make our work become easier we tried to do and understand one of Read more
Surprisingly, I was extremely efficient in my last week in AESTE. I have almost finished up every basic functionality of the project that I was supposed to do: Caching, Interfacing with the editor, REST Web API, Cloud Storage, User Interface and many others. Firstly, I’m very glad that I have gained a lot of useful technical skills through my entire internship, and clearly this is one of the best choice I have ever made to join AESTE as an intern.

This week, I wrapped up work on separating the USB features of the firmware which consists of the HID Keyboard and CDC Debugging Console into 2 seperate files together with 1 USB base file where functionalities are shared. These were written to resemble a library which helps to simplify usage of the USB functionalities when other features are built on top of them. After wrapping up work on the USB features, I then started to work on the modem features Read more
I began breaking down the entire project with many mini tasks and went on finishing up sorting the JSON objects for LISTING. Though having done this, there are still many other tiny tasks that need to be finished such as grabbing the image from the editor and hosting it as a URI, interfacing with the editor, integrating javascript Dropbox SDK into the front-end to get the dropbox token and bitstream URI. After finishing up the sorting without testing it, I Read more
This week, I was able to pinpoint the reason behind the erratic behaviour of the board. Upon rereading the documentation for the Harmony USB Libraries, I found out that in particular for the PIC32MZ family of microcontrollers which includes the board that we were working on, the buffers that are sent to most library functions are required to be placed in coherent memory and aligned at a 16 byte boundary. This was not needed in the Ethernet Starter Kit as Read more
This week I started working on front end for Dashboard. Dr Shawn has told me all the functionalities and all the things that are needed for the Dashboard so I need to find ways how to make all the things work. Actually it is quite hard for me to do the front end as most of the things that need to be included are customized so I spend a lot of time studying and trying to understand about admin on Read more
This week, I explained to Dr. Shawn about the fact that the USB code managed to work on the PIC32MX but not the real boards in which he suggested to reduce the clock speed of the real boards to match the ones on the PIC32MX as it could be some form of rate-limiting for keyboards since the clock speed on the real boards were higher. Tried it but unfortunately it did not work. However, the rate-limiting idea gave a bit Read more
