Sunday, May 18, 2008, 01:02 PMI received the Silabs programming kit with a lot delay, but hey, there it is...
So today I created a schematic to discuss with the original developer, Miguel Angel Rodríguez Jódar, and couldn't resist to also create an example PCB.
Watch and dribble (or maybe not...):
Sunday, May 4, 2008, 07:04 PMWell, it's not really an update on progress, but only to inform the impatient I'm still waiting for some main components for the prototype ;)
I was hoping I would have received them already, but it was hard to find out what programming kit I needed to order; I hope I'm waiting for the right one to arrive now... This kit includes the latest USB programmer from Silabs, and should also include the IDE wìth assembler.
I have absolutely no idea why the online free IDE from Silabs does not include the assembler...
Here's a teaser of the soldered Silabs microcontroller on a prototype PCB ;) :
Friday, April 18, 2008, 01:45 PMWell, the Silabs microcontroller for the prototype has arrived (lovely service of Mouser.com, shipping only 3 different chips without complaining about the order quantity).
I also ordered an adapter board to solder the microcontroller onto, so I can use the chip on an experiment board.
Yesterday I got my hands on an eBay auction for a Silabs development kit for a nice price, so I'm almost ready to build the prototype.
To awnser some questions to the replies on my earlier posts: this project is based on an entirely different microcontroller than the one used on the Kempston Mouse Turbo.
That means it's a real lot work to combine the two interfaces in one microcontroller.
But it should be possible to integrate both onto one final interface. But if anyone is interested in such I doubt; all of you who are interested in this project will probably already have a Kempston Mouse Turbo interface.
I'm thinking of developing the final PC keyboard interface on a very small PCB, that is flat on your desk (not upstraight), so another interface can be connected to it directly, something like this:
That way costs will stay very low, and assembling will not take too much time.
Saturday, April 12, 2008, 07:47 AMThe first auction was a succes, so here's a new one:
Enter this number on your local eBay site.
This auction does not include the free optical scroll mouse, because I don't have any more!
Friday, April 11, 2008, 12:58 PMI updated the Quick Reference Manual for the Kempston Mouse Turbo with information of how to use the Extra Mode.
Here's the link of the PDF.
