Today I put in more chips in the Hardware simulator. I downloaded the hardware simulator the first week and it took me awhile to figure it out. I've put in the and, or and xor. I think that was all the ones covered in the first chaper. I'm going to start Chapter 2 on Boolean Arithmetic today. From looking through the chapter it goes over Half Adder, Full Adder and Adder.

Today I worked on the full adder and half adder chip in the hardware simulator. I did all of half adder and most of the full adder. I can't get the full adder .tst file to load so I'll never know if its right. I must have changed it sometime when I was messing around with the files. I just tried to load the .tst file and it worked that time. I don't know what happened the other few times I tried. I'm working on the inc16 chip now but so far I havent got it to work yet. Theres a comparison error somewhere on line 2.

So far I have done a few more chapters or pieces of chapters in the nand2tetris book. I've been doing the homework assignments for Joe so I think I'll probably focus more on that for now. I'll still do some of the chapters and stuff in the computer organization lab mostly just because if the cpu emulator doesn't work I still want a grade for something. So far I'm on chapter 3 in the book and trying to get stuff to work. I got the register.hdl to work and im trying to get the RAM8.hdl to work but the .cmp file wont load for some reason.

This week I have been trying to catch up on some of the stuff that I forgot to do or wasn't sure how to do so I got some help. So far I have all the logic functions like and, or, not, nand and xor done. I also have some of the latches done but I haven't tested them yet to see if they actually work. I have pretty much stopped doing the book mostly just because this is a lot more interesting and the book kind of sucks.

I have been working on the jk flip flop recently. I had to fix some errors on the multiplexor a few days ago but now I think it works how it is suppose to. The jk flip flop is really hard to get going for some reason. I dont think I understand it completely and the whole class thing is still kind of confusing in some ways. I do understand what the constructor does now and am a little more comfortable with objects of classes and how to use them and stuff like that.

I think I have the jk flip flop done but im not very sure. I have something but I havent really checked to see if it works or anything.

I've started working the two input demultiplexor and the four input demultiplexor. I pretty much just realized I forgot to do them so I guess I should probably do it. Hopefully thats about the only thing I forgot to do.

I've finished the one to two demultiplexer and the three to four demultiplexer yesterday. I realized earlier that I messed up something really simple and I have to fix that later, but besides that im done with them.

We have been following the lazy foo sdl tutorial for the last few weeks. So far I have done lesson 5 and will start lesson 6 later today. The tutorial goes over pretty much everything so its easy to follow along. I found the lazy foo tutorial on adding sdl to xcode so I'm going to try and add the sdl library in xcode later today. The first tutorial I tried on youtube sucked he did it completely different.

This week I am still working on the lazy foo tutorials. I just finished lesson 7. I might skip a few tutorials to get closer to lesson 18.

I am a little further than the last time I put an entry in and I didn't even skip any of them. I Just got done with lesson 12 which was on timers in the SDL library. Lesson 13 is on advanced timers so hopefully it will be about the same as regular timers from lesson 12.

Im just getting done with lesson 13 I still have some errors to fix. Hopefully I wont have as many errors or problem with the next one but I probably will since they seem to be getting longer and more complicated. Lesson 13 seemed to take forever.

I have still been working on the SDL tutorials on lazy foo. I finished lesson 17 the last class so now I'm on lesson 18 now and this is the last one before I try and make pong. I'm glad im about done with the tutorials and can start working on one of the projects. I finished lesson 18 before the end of class so now I guess its on to pong. Hopefully it wont be too confusing putting all the pieces from the tutorial together.

I have started pong but I havent got very far with it yet. I've just added the timer and ball class from the tutorial so far. I'm trying to decide what picture I want for the background and ball its a tough decision.

Started working on pong today in class. I didn't get very far I was mostly just seeing how close some of the tutorials would be to the actual pong game. I also took my time filling out teacher evaluations so the class went pretty quick.

I'm a little bit further on pong but not a whole lot. I haven't worked on it too much yet and hopefully it will be a lot like the tutorials.

Pong is kind of coming along but not very fast at all.
