Wow, that seems really - really annoying!

Can I tempt you into using basic and a pic microcontroller The code is much nicer to play with and you don't have all these annoying things that arduino seems to have.

[Saimaster13]

Not for this project, not after I made all this code. For the next project, you might be able to tempt me though. So all you have to do is define it as const?

[Saimaster13]

I got it! Thank you, Arduino forums.

It is a whole lot easier in only one dimension, so I just did that and made a little code to switch between the maps.

Anyway, to store a variable in flash, first you have to declare it:

Code: Select all

const prog_uint32_t MAPGreen3[97] PROGMEM = { 0, 1, whatever numbers you want};

The const is not actually needed but doesn't hurt (or do anything.)
prog_unint32_t is PROGMEM's unsigned long variable declaration, be sure to use the PROGMEM version if there is one (check the Arduino PROGMEM website for more special variables)
MAPGreen3 is my sting name, and it has 97 different numbers
PROGMEM can either come before or after everything to work. (I did after, there is no difference though)


The variable is now declared, but you will probably want to use or retrieve it in your code:

Code: Select all

pgm_read_dword(&MAPGreen2[x])

Writing that would be the same as writing "MAPGreen2[x]" if the variable was stored in RAM.
pgm_read_variableType(&variable) is the format
The "dword" variable type is 4 bytes, there is also 2 bytes "word" and 1byte "byte" (there might also be char, I'm not sure)
Remember the &
Write the string or variable you want to call.
The x is what string value you want.


Good luck guys

Got another update video.



I got a second controller working since the video and tested the game with some friends. Surprisingly, its pretty fun just pushing people around with the shield.


Controller:


There are some bugs though:
If you move into a person's shield with your sword out, you will hurt that person (should be easy to fix by loading the shield data before the sword data)
There is a glitch where you can go through walls when another person is pushing you though with a shield (should be able to be fixed with another loading order change)

I am thoroughly impressed!

Love the new video as well. I can't get over how much you are just like me! going through your code there are so many similarities as to how I would go about making a game like this. Just let me know how you would like the level converter for the game to operate and it will be simple to get it going for you. I.E. if you want it to be able to output 32 bit words etc... Just send me the details in a PM and i'll work on it over the next few days when I get some time.

I was especially impressed with how you can go into a house and it then changes to show you in the house. It really goes to show that you don't need great graphics to have great gameplay - you just need to have some little pixels and a good story line

How much does it compile to now? do you think you might need external memory - maybe a serial eeprom?

[Saimaster13]

How much does it compile to now? do you think you might need external memory - maybe a serial eeprom?

It now compiles down to 14kb with 4 maps. I did some math, and believe that the maximum amount of 64x48 pixel maps that can be programmed is 25, then the Arduino's data will be full. I definitively don't need serial eeprom right now, but I might later if I make the game really big.

What I do need is faster refresh rates for the matrices I plan on upgrading to. I believe that with how big I want to go, the Arduino's fps (I have an in code function that calculates it) will be too low, so, the only thing I can think of is getting more Arduinos into the picture. What I have no idea about is whether I should send data from the main Arduino to matrix driver Arduinos, or add a data manager Arduino between them. (If there was only the main Arduino and the display Arduinos, then the main Arduino would send the cathode data to the appropriate display Arduinos which would then scan the rows and display that data. If a data manager was present, the main Arduino would send the player's positions and whether the player's swords or shields were out or not. The data manager would then calculate the cathode data and send it to the display drivers. The problem with this approach though is the eventual expansion of npcs and enemies: it would be hard to fit them in.) Another problem of mine is that I have no idea how to send data between Arduinos at an efficient rate (my first idea was to use shift registers connected to 8-3 decoders connected to the display Arduinos to tell them what to display. Is this an efficient way, is there a better way?)

So, simple answers:
I do not currently need more memory
How should I communicate to other Arduinos efficiently? I am looking for the fastest way with the fewest delay()s. Also it should be noted that I only have ~3-4 pins available on the main Arduino (but 20 on the others.)

I'm glad you like the game by the way!

I just realized: I do not know how to adequately power LED matrices.

What I need for right now is to know how to power two or four 2x2 matrix of 8x8 matrices.
Where each x is a 8x8 matrix, what I am making will look sort of like this:

xx xx xx xx
xx xx xx xx

Either all of them will be driven together, or the first two 2x2 matrix of matrices will be driven together, and the other matrices will be driven separately.

So it is effectively going to be either a 2 row and 4 column matrix of matrices, or a 2 row 8 column matrix of matrices, totaling to either a 16x32 or 16x64 pixel matrix.


My hardware:
Arduino
74HC595 shift registers
eight 8x8 matrices (I will eventually get 8 more to double the matrix count.I have yet to decide whether they will be powered by the same Arduino or not.)

Also, it should be noted that I have 74HC373 and '374s, but do not know how to use either. Should I use one of these instead of the '595s?


What I have on hand for current (sinking or sourcing, I'm not sure which.):
resistors
10x ULN2803APG transistor arrays
2n2222a Transistors




I am willing to get whatever I need to properly power the matrices. However, I would prefer, if it would work just as well, to use the transistor arrays I already have to power the matrices.

I just typed up the intro. It now compiles down to 20kb. So what was that about extra memory and serial eeprom?

[Saimaster13]

Another video showing what scripts I put in so far. Since the video I put in a start menu and introduction text explaining why you are there and guiding you to what happens next (not that there is currently something that happens next.)

Another controller is under construction and when I know how to properly sink and source power to a matrix I'll make two bigger displays, followed by a third and fourth eventually.

First of all - the video update is so cool! The LCD screen letting you know what is what really adds depth to the game - I guess it's sort of like reading a book. There are no pictures in a novel but you draw the pictures up in your head. This is shaping up to be an extremely fun game to play. Actually, I look forward to playing it once complete!

Now let me do a write up of your other questions...

[brad]

I just typed up the intro. It now compiles down to 20kb. So what was that about extra memory and serial eeprom?

I would use a serial eeprom (or perhaps SPI memory) to hold onto all of your constants data (like game screens and LCD text etc...)

That way all of your program memory will basically be used for just the game code. The code will then call data from the external memory when it needs to (just as it it was calling it straight from program memory.)

Have a read through this for more info:

The main problem here is the amount of rows being activated at once is not enough. Let's just say that you are sending out 1 bit every 1uS. If you have a bi-color 8x8 matrix then it will take 8*8*2 = 128uS to send out your red and green colors to the display. You then need to allow a delay of perhaps 1mS for each time you activate a row of LED's - so you have and extra 8mS delay for an 8 column display. If you then go worst case scenario and have a 64x16 pixel (bi-color) display then you are looking at needing 16 of these 8x8 matrix displays. so:

128uS to send data out per display + 8mS to actually be able to show the image multiplied by 16 displays = approx 130mS all up. That's just to scan through once. But you need to be updating these displays at a rate of around 24 times a second (to prevent flicker)

But if we run the math 1/0.13 = 7.69. That means that you will only be able to show 7.69 frames per second which means a whole lot of flicker!

So what if you where to use 74373's? Well, this would help, but only slightly - the only difference here is that you are sending a whole byte out to the matrix per clock pulse instead of only sending a single bit per clock pulse. this means that you will wipe out 7uS per row per display So:

7uS * 8 columns * two colors * 16 displays = 1.79mS this means you will have drawn one image 1.79mS quicker than if you sent the data out serially. It did take 130mS previously so now it will take 130mS - 1.79mS = 128.21mS which is still not quick enough!

Notice how we don't really have a problem with how fast we can send out the data? the main problem is with holding the data on those LED's for long enough for us to see them properly. What you need to do is send multiple rows of data out at a time, then turn on multiple rows of LED's at a time, before sending out the new data.

hopefully this picture should help!

I don't understand how I would split an 8x8 matrix into 4 rows. Wouldn't the cathode data be doubled on a single matrix if two rows were active at the same time? Also, to provide the extra mA needed to power larger matrices, won't I need to add some transistors to source and sink power?

Also, you plan on building this project once completed?
