Data Input Form

Continuing the Lab 4, we are going to develop the option 2, data input form. The goal is to prompt the user to enter its name, address, city, province and postal code. Also, letting the user use up, down, left, and right arrows to navigate throughout the fields. After finishing the data input, a summary is presented at the end.

Using the ROM routines, wasn’t too hard to allow users to type data into the character display. Then, I decided to make the filed names with the same width, 14 characters, limiting the input to 40 characters. So, the user is not allowed to type in the first 14 and after 54 characters. When the user presses enter at the last field, the summary is shown. I could display the fixed message, but I couldn’t copy the inserted data. I’m still working on that, and I’ll update this post as soon I figure it out.

It is frustrating for me to spend days in basic problems that could be solved quickly using other languages. Assembly is not captivating me at all. Perhaps, this is a lesson that would make me a better developer. I believe in the SPO course and hope to use upper-level languages soon.

Two-digit Numeric Display - Final

Photo by  Nick Hillier  on  Unsplash In this post, I’ll continue the two-digit numeric display. If you miss it, click here and check it out . To finish this project, we just need to show the numbers in the matrix-pixel (the black-box in the 6502 emulator ). To kickstart, our instructor gave us one example of how to display graphs, which was a lot helpful. The first thing that I’ve noticed was the bitmap table at the bottom. So, I mimic it and made ten tables like that to represent each number (zero to nine). So far, so good! Then I grabbed the logic to display one digit, and then my nightmares just started. How to place two graphs (one for each digit)? How to switch from one number to another? How to reuse code? Where is my coffee?! To emulate some if-elseif-else statements, I used jmp (jump). They are all over the place! However, the 6502 limits the jump range from -127 to 128. That means moving the code-blocks to satisfy all jumps limit. For e...

Project Stage 1

Photo by  SpaceX  on  Unsplash Hello! This is my SPO 600 blog, and this post will be long – sorry. The goal is to pick one project that is CPU intensive, written in C or C++, and experiment different compiler options and present the results. That’s why it will be long – lots of data to show. I choose the AWK project ( https://github.com/onetrueawk/awk ). It is a handy tool to process files. Parse, sort, and filter are some trivial operations that are CPU intensive. To make it harder, I created a huge XML file to parse it and count the tags. I've described the machines in my last post, if you miss it, here it is . I also created a script to run and collect the data. I planned to run each candidate 10 times, but a few attempts didn’t receive any data. So, I decided to nest the loop in a way that even if someone kills my process, the data could be used. Guess what? It happened! To produce the candidates, I just changed the CFLAGS inside the makefile and ran the...

Assembly?

Photo by  Jonas Svidras  on  Unsplash Last week on my SPO course, I had my first experience writing Assembly code. I won’t lie; it was struggling. For me, Assembly is like the Latin of the codding languages and “carpe diem” wasn’t my first lesson. Hexadecimal, binary and a list of instructions is a must know to guarantee survival. Our instructor introduced us to the 6502 processor: it is an old school chip that was used in many home solutions such as PCs and video games. Internally, it has three general-purpose registers, three special-purpose registers, memory and input and output ports. Fortunately, there are emulators on the internet that helps us to focus on the development, hiding the electronic part from us. http://6502.cdot.systems/ Using the emulator, our first task was to copy, paste and execute a piece of code to change the colour of every pixel in the display matrix. That was easy! The result was a yellow screen. Then we were asked t...
