USB Resource

USB Resource

2005-07-23 by majid_mokhtari

Hi everybody ,

I have just started using USB instead of RS485 in an especial medical
instrument . I am surfing on the web  to find a good and practical
resource  for introducing USB Protocol . It's planned to use  LPC2138
, although I am also searching for USB controllers .

Any advice is welcomed ,

Majid

Why use the LPC2138? It does not have onboard USB and needs an extra chip via 
serial. THis limits what you can do with it.

How about trying the ATMEL SAM7S64?

As for resources, the most helpful thing I have found with USB is using libusb 
(ask uncle Google). This cuts through all the bull of writing drivers etc and 
gets you going a lot faster, as well as being OS independent.

I find your logic to switch from RS485 to USB curious. They perform very 
different roles. USB is good for communications between a device and a PC. 
Between devices, CAN is a very good idea. CAN provides a similar function in 
many ways to RS485 in that it is peer-to-peer and multi-drop.

Re: USB Resource, use LPC2148

Hi Majid,

the LPC2148 (or for smaller programs the LPC2142) are almost the same
devices as the LPC2148, just 2 analog inputs turned into D+ and D-
A board from Keil seems to be available www.keil.com/mcb2140

Cheers, Bob

Hello,

you should also take a look at the TUSB3410 from TI.
