My progress is very slow as I merely managed to complete one module, which is the sensor module. The sensor finally worked on the simulator. Whenever the touch pad is clicked, the sensor will detect and return HIGH. The user can then perform any actions based on the output from the sensor. The next module I am working with is SPI (Serial Peripheral Interface). SPI is basically used for communicating with one or more peripheral devices quickly over short distances. Read more
On Monday, my boss stated how important it is for an application to be easily set up, without the need for user to define ports, address and configuration files. Confusion and havoc will ensue when we leave things to the hands of the users. Therefore, an auto-configuration logic would need to be embedded inside the app startup itself. So, i re-read the WServer API and found out about setServerConfiguration, which is executed in main() body. It accepts the arguments passed Read more
This week, new task had been given, which is to design a testing circuitry for the new board that arrived! Wiki Documentation Most of the time I spent is to write the wiki of the project that I had been working for months. Surprisingly I found that some of the wiki that had been done previously was incomplete, and I have to edit them. Then the task continue to write the wiki using markdown language which is pretty straightforward. Code Read more
This week I test the board that I design. The details of the board are explained in previous post, my first objective would be to be able to program the PIC32, confirm the osciallator is working, able to communicate with a LAN8720 to have internet connection. Programming PIC32 To program the PIC32 of the board is fairly simple, with just a PICKIT3 (since I;m programming the board through ICSP). The hardware connection can be refer to Microchip: Programming & Diagnostic. Using Read more
After two weeks of work absence, I am finally back. This week, I worked together with my colleague Peter to debug the product and also improve on its functions. A weird thing happened although we were using the same codes, which is:- Wt.emit in browser unload event Peter seemed to be able to emit a signal to the WApplication during the browser unload event which was 100% unsuccessful for me. The only thing working for me was an ajax request. Read more
This week I was suppose to work with MSPI (Master Serial Pheriperal Interface), however I didn’t manage to complete the sensor module. So I had to continue with it this week. The digital touch sensor I created was incomplete as it is unable to be used like the sensors in real world. So this week I have to complete it’s function. For digital sensor, my idea was creating another rectangle to represent the touch pad, so that whenever a user Read more
Last week I have understand the whole project system, so starting from this week I will begin to start my task — Implementing IO modules into the simulator. Dr Shawn advised me to start with the easiest modules, which is the sensor modules. Sensor modules are easier comparing to other modules as their functions are just detecting events or changes in real world, then provide a corresponding output to the device. I started my task with Digital Touch Sensor TTP 223. Read more
This week has been spent mainly on documentation of the previous work that had been done. Simplify Code Documenting the code is reminding myself on why do I write it in the way at the first place. Some of the code often comes with unused variable and function where they could be deleted. Thus, I try to clean up most of the code and simplify some code if possible. Also, I helped on documenting those code that has not been Read more
This week I was assigned for a few tasks. First, I need to study the codebase of the project system to understand how they are related and how they work, especially the simulator part. Honestly, I was having hard time when reading and analyze the codes written by other interns. However, with the help from JeunHo and Khai Yong (seriously thanks a lot!), I was able to understand the system deeper in overall. The next task is, I need to Read more
This week, I continued with my previous week task, to find the way on how SPI C code actually work with the Verilog module. I stared on the same circuit for hours, but then I still could not find the way to integrate them together. And finally I decide to search in the Internet, finding as many clue as I can. However, then I realized that the SPI module that the previous intern written has only two address that control the data Read more
