Exclamation USB and Mac Support for IFI FRC Controllers???

I heard a rumor this past season that Innovation First, Inc. was going to convert FRC Controllers to USB data transfer. In doing this, it would enable the Mac to be able to hook up to the Robot Controller and download software. Anyone else hear this, because it would be awwweeessoommee!

EDIT: Innovation First, Inc. has denied my request for confirmation on this issue.

Not just that but imagine the new joystick options.....
No i haven't heard that but i know allot of people want to see the IFI controllers USB enabled.

I'm not sure if the joysticks are going USB, because then we would be able to have unlimited awesomeness, but I was just talking about the Program port.

That's quite another topic. To use a USB connection to the computer for programming, the RC would need to be a USB slave. That's pretty easy, and relatively cheap. To use USB joysticks would require 1) being a USB master, which is a bit more expensive in both parts and firmware, and 2) USB drivers for any joysticks to be connected.

A USB-to-serial converter can already let a Macintosh connect to a RC's program port, by the way. Making use of that connection is only a matter of software...

Re: USB and Mac Support for IFI FRC Controllers???

USB would be awsome as less and less laptops are supporting the parallel ports, and it even opens the possibility of having those sub-compact notebooks to program on (and yes, Macs!)

I wouldn't be surprised if IFI is working on a new product using USB, but I have no insider information.

Re: USB and Mac Support for IFI FRC Controllers???

I will bet actual money this doesn't happen. Serial port based PIC programming has been around as long as PICs have, and to my knowledge no microcontroller out there doesn't use some form of it. None, to my knowledge, use USB. Why bother? It would be much easier to include a serial->usb converter in next year's kit.

And what about the Mac part of the rumor?

Re: USB and Mac Support for IFI FRC Controllers???

I would imagine, if the RC were to have a usb port right on it, it would have a USB to serial chip right on the board. By providing their own converter either on the board or in the kit, they can control the parts that are used, only have to worry about 1 driver, and ensure that speed is acceptable. We have noticed problems using usb to serial converters and that some take significantly longer to program the RC than a real hardware serial port.

Also, there are several PIC's that have USB capabilities, although I am unsure if they allow in-circuit programming over USB.

OK, this is going to seem a little dumb, but define 'PIC'.

Re: USB and Mac Support for IFI FRC Controllers???

huh, guess I don't know, if it is an acronym. Its the main (only?) series of microchip microcontrollers though, two of which happen to be onboard our controller.

And by the way, this has been mentioned before, but with a little work and a usb stick that uses 100k pots, you can quite easily convert a usb joystick to serial. With a certain limit on buttons/axis's obviously though that usb doesn't have. but who needs 10 buttons and a pov on 1 joystick for driving a robot?

PIC stands for Peripheral Interface Controller. We have two PIC18F8520 chips in the RC controller from IFI. One is user programmable and is what we are changing when we download HEX file programs on our robots.

Mike

Good to know it's on the list of things to do, although not surprising it won't happen next year.

BTW, is your car still in Dayton?

So, does the "this" refer to USB support, Mac support or both?

I'm guessing USB - and thinking maybe IFI has better things to do than try to support development environments for Windows and Mac OS? Don't take me wrong - I think Macs are great (as he posts from his trusty Tibook) - I just think software to support new and wonderful sensors and higher control system reliability might benefit more people.

So sad But glad to know it is comming. Eventually.

And on USB to serial converters- Most are designed to work for PDA's and will work fine with PDA's and some other devices, but will be drastically lengthen the transfer time. We had a 400MHz school computer as our programming computer. It would transfer the file in, oh, I would say 15-25 seconds. But would be forever compiling. We tried a USB to serial converter with a newer laptop (1.7Ghz ish). Compile in 1/4 the time, but took about 15 minutes to transfer the file. But this wasn't durring the competition, so it didn't hurt us and we knew not to use it when time counted. And the converter we used does work on my dad's old Palm Pilot with much better transfer rates. So it wasn't that the converter was faulty.
