Hi, I’ve had this project in my mind for a while and I’ve been looking for things to help me get started for weeks but have had no luck. I would like to create a custom USB HID device, probably a joystick of some kind as a custom flight simulator controller. I know I could use an Arduino Leonardo or other microcontroller with USB built in, but I would like to take this opportunity to use a chip such as the MAX3420E (which seems incredibly complicated from the code samples supplied) or some chip from FTDI. I was looking at FTDI’s website at different chips (specifically the FT201X because it has an I2C interface) and I read on their FAQs that you can’t change the device class of their chips because they use a custom one, so you can’t use them to make a HID but then I came across the FT120 which has some weird multiplexing interface and they have sample code for it on how to make it a HID!? :~
Alright that’s enough waffle :P. What I would like a bit of help with is if anyone has had any kind of experience with using a dedicated USB to other interface chip, which one(s) or specifications I should be looking out for or whether I can use a chip like a FT201X to make a HID because on their corporate brochure I found http://www.ftdichip.com/Corporate/FTDI%20Brochure%20Nov12.pdf ← there on the 4th page it says
FTDI offers a comprehensive range of ICs for USB peripherals, including bridge chips and devices targeted at standard class driver support.
and second on the list is that FT201X. I am thoroughly confused and would be extremely grateful if someone could shed some light on this.
