New USB toy

jackinnj · 10th March 2007, 12:47 PM

A couple weeks back Maxim had an advertisment in EDN featuring one of their ADC's and the USBMicro interface -- I purchased a U421 online -- if you have even remotely adequate VB skills this device has all the HID stuff built in so you can just delight in the 16 I/O lines, and it would seem easier than using the FTDI chips.

Can you provide a part number and a few more details? I did a quick search and didn’t find anything similar. Is this A/D or DAQ stuff?

Thanks

www.usbmicro.com -- you will have to interface your own ADC or DAC -- which is just as well anyway. There are some routines on their website.

Jan Axelson provided some links in a recent Nuts N Volts article -- the folks at www.dlpdesign.com have some USB controllers with canned user-ID's which relieve you the necessity of writing HID code:

here's a controller interface using the SX chips from Parallax -- a blazing 50 MIPS:

the pix are a bit nasty-big to put up, follow the links.

Jan's website is www.Lvr.com -- she has written 5 or 6 books on communications and interface,
