Take a look at this

https://www.pjrc.com/teensy/

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

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.

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.

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.

USB / good board to get feet wet with USB HID
« Last post by ieee488 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.

F72FE0D4-CBCB-407d-8814-9ED673D0DD6B   it looks like a interface GUID, what difference between 1st and 3rd ?

yes to the others

Hi Jan,
  Thank you again. I will study your suggestion. May I learn another question?
There are 3 GUIDs , I  google them from web and try to identify them,
1st: 4d1e55b2-f16f-11cf-88cb-001111000030   for USB HID interface, correct?
2nd: 745A17A0-74D3-11D0-B6FE-00A0C90F57DA  for USB HID Device, correct?
3rd: F72FE0D4-CBCB-407d-8814-9ED673D0DD6B   it looks like a interface GUID, what difference between 1st and 3rd ?

Note: I use your winusb_cs application tool to find my device, the ClassGUID of device information shows  745A17A0-74D3-11D0-B6FE-00A0C90F57DA , so  my device is HID device , correct?

Note2: I think the winusb_cs uses the VID and PID to find the device, the setting of GUID interface won't effect the searching, correct?


thank you in advance,
Eddie
