A project log for Mini rpi2 laptop

Small form factor laptop in the style of old HPC's like the Jornada.

I managed to get the teensy working. For some reason my windows laptop wouldn't see it anymore so i tried my main Ubuntu pc with arduino ide. At first it wouldn't work but then i tried starting the ide with sudo, then i managed to get blink working again.

So with that out of the way it was back to work. When it comes to programming I'm a noob, and by noob, i mean i don't know didly lol! So i managed to find a project from a couple years ago similar to mine in which someone named Karl Lunt put a raspberry pi inside an old trs-80 portable computer. He hooked up a teensy to the keyboard to get it working as a usb keyboard for the pi. Here is said project and he (Karl) was nice enough to share his files he made to program his teensy. Now i really mean it when i say i don't know how to program. I opened the hex file in gedit and took a look at the code. I think i can modify this to get my keyboard to work. I flashed his unmodified hex file to my teensy with teensy loader and would you believe, it shows signs of life! Now only 4 keys function, and they don't even type the correct characters, but i think I'm headed in the right direction. I know his matrix is different then mine and if i can figure out what to modify in his code i can get it to work.

I'm going to concentrate on the keyboard part first, and then I'll work on getting the joystick as a mouse part after. I wonder is there any way i can get his code to work in the arduino ide? Maybe it'll be easier for me. I thought it would be neat if i could program the teensy with the rpi2 itself. I installed the arduino software but i ran into trouble when i tried to run the teensyduino installer. The version i had wasnt designed to run on arm processors so i gave up.

Here is a short video i made of the keyboard buttons that work and also i modified the front hinges so now the keyboard flips all the way over so i can access the inside better.

I'm going to do a project log about how i modified the hinges just to have it on here.
