TI-Nterface (my version of labpro)

nice it's good to see progress on this, it might be very useful when finished..

Yeah. I dunno if I'm gonna make it in time for our schools' deadline. I'm trying hard.

[Nick]

oh? when do you have to get it ready? that's a nice schoolproject.. what kind of studies are you doing?

Secondary school I hope to graduate this year.

Artwork on the front of my essay

[Nick]

wow, great, i love it did you manage to make it ? (maybe you already said it somewhere, but i must have missed that if you did)

Not yet. I got stuck. programming those microcontrollers is a little weird. I cant find working code examples for my compiler. I am still gonna build the thing. It is just gonna take some time

[DJ Omnimaga]

Nice, and when you did your presentation you should post a video of your device in action an d put it here

[Keoni29]

I just printed my essay. I woke up earlier to make a presentation for Life Science and Technology So much to do. Tomorrow a Dutch test and more tests next week. My presentation is February 20th. I really hope I have a working prototype by then.

[DJ Omnimaga]

Oh ok I was sure it was pretty soon, like tomorrow, and that you already finished the prototype.

[Keoni29]

I wish I had, but things went a little different.

[Keoni29]

I'm working on the device right now. I hope it's finished by Wednesday! (otherwise I am f*ckd)

I, and many others, including you Keoni, have been wanting to interface the calculators serial with an Arduino. I've coded only sparsely in my life, just enough to get by. I use lots of example code to write programs, they're my crutch. So basically what I have right now is a Arduino program that sends a byte repeatedly through the link port using Kerm Martian's whitepaper on the Calcnet protocol to fix my timings. But the calc still receives nothing. I am using two programs on the calc to receive a byte. The built in GET command and my Omnicalc linkreceive() command. Neither of these get anything from my program on the Arduino. Here is my code:

I borrowed a usb interface a while ago. I was able to recieve bytes with it from the TI-84+, so I'm trying to port the software to the arduino and hope it will work

Good luck Keoni29 on finishing this in time. X.x

Also welcome here adept. Nice to see another hardware guy around.
