good board to get feet wet with USB HID
« on: February 14, 2020, 03:30:31 pm »
Which board would you recommend for getting "my feet wet" so to speak with USB HID ?

I purchased a Teensy LC ( www.pjrc.com) and have uploaded their USB Raw HID to it using the Arduino IDE.
It works although the device shows up twice in Windows 10 Device Manager.   ???


My goal is not a keyboard or a mouse, but for the board to send packets of information every 100 ms or so.

I would suggest any board with good support from the vendor and/or the community and an architecture and programming language you're familiar with.

Microchip is one of a number of vendors.

Microchip's website is bit disorganized for my taste.
Is there a low-priced evaluation kit you can recommend from them?

I am doing this as a learning exercise, so I don't want to spend much money.

Thanks.

Do you need to buy an eval board? The hardware is dead simple, why not just use plugin breadboard. A 18F25K50 doesn't even need a crystal!

So, you don't believe that it is unnecessary to buy their PICDEM FA USB Demo Board : https://www.microchip.com/DevelopmentTools/ProductDetails/PartNO/DM163025-1 ?
It is a bit pricey for me.

If I just buy the 18F25K50, don't I need to buy a USB breakout board so I can connect up to my PC ?

I was hoping for a $20 kit.

I purchased the Teensy LC and have it in my possession.
I will work with it some more.

Thanks.

Right, you said that! I think it's a good choice. Good luck with it.
