eog mouse

I am a beginner at working with microcontrollers. I am working in a group on a design project which uses electrodes to track eye movement. The voltages from the electrodes will be filtered and then input into an A/D converter on a microcontroller. The micro will be connected to a PC via USB and will act as a USB mouse, moving according to the different voltages. I was advised to use the PIC18F4550. Is this a good suggestion? Is there anything in particular I may have overlooked or should consider? Are there any places (besides of course the manual) I should look for help?
Thanks!
 

eog mouse

I chose to use the PIC18F4550 for the mouse simulation. It will take in voltages using A/D and depending on the voltage, move the mouse the appropriate direction.

I do not know much about the USB mouse interface, though, using a PIC18F4550 even though many sites mention USB mouse as an application of this micro. Are there any references on this? I've been looking but it doens't seem like a popular project idea.
 

eog using microcontroller

Hi

Use the STM32 arm cortex it is much faster micro ,who is capable of doing more task (like digital filtering) insted of just moving data to PC for analyze


all the best

eog，mouse

the microchip USB framework comes with a HID mouse example for the pic18f4550, maybe it could be a starting point....
 

Thank you for the replies!

I did end up finding that mouse example last night. It seems a bit over my head but I think I can figure it out.
