 |
|
| So, after seeing Sami's project that looked relatively simple to make, and it features removeable storage, and it is already compatible with the TI-OS with no program, I started looking around, and what do you know, my dad has a p16pro40 programmer and a pic16f84-04/p chip! So now, I might try to build one. Also, seeing as you can read/write a psx card with a computer interface...this is an interesting idea. If I made a working adapter and bought a memory card, would anyone be interesting in the hex coding for the pic part? |

I have to admit, that didn't cross my mind, but...here are a few advantages:
-No drivers for different branded cards
-No program to send/recieve files other than the built in one on the ti-os
-Works for almost all TI graphing calculators, not just the 84+
I thought about selling them, but, although I would like to think I am pretty good at soldering, It is annoying to me to solder for long periods of time and I tend to get destructive with it after I do it for so long, but we will see.
I dropped a bid for $5 shipped on a PSX memory card with 4MB and an LCD screen, I might win, (I hope so), If I do, the project will go on. If I don't I guess I'll have to wait and bid on a 3 pack of 1MB cards or something. |

His PixPander doesn't work; ever wondered why it's been at 0.1 Beta? I've built it before, and so have several others (although there was one guy who got it to work, but he completely redesigned it; he didn't say how he did it though; I'm thinking that the PIC code is good, but I've noticed tht his schematics and placement/values of his components is preety shoddy (especially since he was going for his PhD at the time)).

| Interesting. Do you know who this is or how I can get in touch with him? If I could just get it to work, it would help me alot since I test alot of different things on my calculators at home and in spare time at school since I am back, and it does me no good to have a blank calculator in 1st period. |

Well, maybe a fake ram clear prog would be a better solution for you...

I'm pretty sure that Sami's not really a member of the community anymore, sadly.

Well, seeing as I'm the only one with experience in this field (this deals a lot with console modding/microcontrollers  ), looks like you and I are going to be working on this (Kerm *might* help us, but he's a little busy with all of his other projects...)
Also, I suggest that we move from PIC to SX procs...because I no longer use PICs  (although I'm preety sure the PIC routines are fine, but as I stated above, the other electrical components and the TI software need to be messed with)

Just to get some bearings straight; about how good are you with ASM (for TI calcs)?

What is ASM? No, seriously, I do know, but I have no clue as to how to program for it, which is why I picked up this project, it can be used in BASIC, which I would like to think I am very good at. I already have the chip, programmer, and everything(almost) I need, so I don't really want to tinker with the design. |

So then how would you have helped before you got banned?

But the problem is with the design because it doesn't work; we would have to re-design (and by the looks of it, I really don't think you're up to the challenge just yet; but if you really want to make a serious go at it, check out my TUTORIALS topic and take a crash course in electronics and embedded design  )

| That's the thing...others have gotten it to work. I think if you added a few caps to smooth out the transfer it would probably help the chance of transfer failure to go down. |

See? We do have to change the design; the component placement is mega-screwed; and it needs to be fixed...hell, we might get away with not having to mess with any code
