From: RobertoB on 17 Oct 2007 10:53 Hello I need to buy integrated circuit to bridge USB on serial port (232, TTL or I2C) but, the question is: I need one with device driver for Windows Mobile 5.0 to use on PDA with host USB port. Someone could list me which device are ready to use with PDA? Or where to find some information? Thanks RobertoB
From: " ctacke/>" on 17 Oct 2007 11:53 FTDI has a CE driver for their chip. Good luck finding something that will do TTL. 232 and I2C are vastly different, so good luck finding something that will do both. If I needed this I'd probably do it with a separate microcontroller and USB to serial converter in a external box that in turn has inputs for 232, TTL and I2C (so you'll need a PIC, some other silicon and some solder). -- Chris Tacke, eMVP Join the Embedded Developer Community http://community.opennetcf.com "RobertoB" <RobertoB(a)discussions.microsoft.com> wrote in message news:C93E6576-7AA2-4B34-ABA9-E70F589D1F1E(a)microsoft.com... > Hello > > I need to buy integrated circuit to bridge USB on serial port (232, TTL or > I2C) but, the question is: I need one with device driver for Windows > Mobile > 5.0 to use on PDA with host USB port. > > Someone could list me which device are ready to use with PDA? > > Or where to find some information? > > Thanks > RobertoB
From: RobertoB on 18 Oct 2007 06:11 It's right! FTDI has FT232R with driver for Windows Mobile 5 and WinCE 5.0. This chip could be one candidate. (I don't need 232 + TTL + I2C but only one of these) My first idea was to use Microchip PIC18F which integrate an USB port. I would like to follow this solution but the question is the Microchip driver seems works only on desktop OS. I cannot find one for Windows MObile 5.0 Two questions: 1. Any USB WinCE 5.0 drivers works well on Windows Mobile 5 ? 2. Is there a generic USB to Virtual Com port driver usable with PIC18F microprocessors family ?

Is there a generic USB to Virtual Com port driver usable with PIC18F > microprocessors family ? Again, not that I'm aware of, but I was thinking in a different order, so you wouldn't need it. I was thinking something like this: PPC<-->FTDI<-->PIC Then use serial to pass commands and data between the PPC and the PIC. However if you only need 232, then you can just get an off-the-shelf USB to serial converter with an FTDI chip in it and use that as is. -- Chris Tacke, eMVP Join the Embedded Developer Community http://community.opennetcf.com |
