Dip ftdi?

Are there any chips out there that are in a dip package that do the same as the FTDI FT232RQ?

Thanks.

    I don't think so. This was discussed in Cluso's n-blade threads, and the consensus was no. You'll have to go with SMD.

    Or find a suitable SMT to DIP adapter.
    I am desperately looking for one for TAOS TCS3414CS.
    So far no luck.

    Hmmm... I did look at that.... What are you referring to with the link to www.parallax.com/detail.asp?product_id=28030 ? It appears to be outdated...

    Thanks.

    and I was referring to the DIP 'FTDI eval' as with image attached .. Don't know where the link you mentioned came from .. The link I mentioned is clickable from my end ?

    I just managed to find it (image attached) - an eval unit for the FTDI 232 - called 'EVAL232R' - I seem to remember a similar DIP configuration eval board also but, as of yet, I have failed to lay my hands on it ..·this one has·a serial DB9 onboard and a USB type B socket ...

    and of course there is the parallax offering ....

    Ok - A link within the thread - I misunderstood you .. my fault..

    Have a look at this though - a breakout Board for the FT232R

    Unless you need full hardware handshaking, the simplest way to implement the FT232R is to buy a PropPlug. All the necessary parts are onboard. Just plug and go.

    Vaati, you can always get and SMD-to-DIP adapter board. I make alot of them for myself - mainly for prototyping. I think I've got a couple of the boards for the FTDI chip. If not, I'll make a few. Want one?

    This is just an RS232 to TTL converter. It has nothing to do with USB.

    So.... What does that mean? "RS232 to TTL converter" ? I'm not so good with chips... smile.gif

    I believe RS232 uses a +/-10V signal to transmit/recieve data. A TTL signal is something like 0V/5V. It basically takes the RS232 signal, which would normally fry any TTL device, and it converts it to a TTL signal that WON'T fry a TTL device. Or am I wrong?

    Phil,

    That is right. One side of the chip is communicating a RS232 signal which is a high voltage (I think it is actually +/- 12 v, but I could be wrong), the other side of the chip communicates at a low voltage signal. The chip itself is transparent to each side, so no protocols are needed for the communication. There are also RS485 chips, which do the same, but the voltage is higher (on the high side).

    Read the Wikipedia article on RS232. That'll explain the voltage levels used for standard RS232 signals. Most RS232 to TTL converters also provide the higher voltages needed for RS232 signalling and protect the logic circuitry from most static electricity and other illegal / abnormal voltages. They help filter out noise that may be on the RS232 lines.

    "I'm not so good with chips..." is a poor excuse for not doing any research in today's world of the internet and the vast resources available. There's plenty of basic explanations available for a quick and simple websearch. For most electronics questions, the Wikipedia is a good source.

    Well, what chip does the Propeller Professional Dev. Board use? Is it the FTDI chip?

    Thanks.

    The Propeller Pro Dev.Board uses a FTDI "FT232RQ"

    I could use a DIP version of this chip too.


    On a side note. I'm not one to grip but.

    Why is it that certain people on this forum feel that it should be Your last ditch effort, when all hope·is lost. And Theirs no other source of info. And its then and·only then, that it·is correct to post a Question in these forums???

    Had I ran into this Negative response when I first started using Parallax products, I wouldn't·be here posting this post reply.

    Wikipedia didn't get Me to buying stuff from Parallax, But the·Parallax forums did.!

    I think these forums should be the first place to look for info for use with the Parallax line up.

    Here, here! This is the first, and in fact the only, place I look for questions on any product or microcontroller from or relating to Parallax. So, does anyone have an idea of how to connect this dip package chip so it connects the prop to the computer?

    Thanks.

    The Propeller Tool has a pdf under Help that shows how the demo board is hooked up. I'm using this as my guide to set up one of these FT232RQ chips to work with the Propeller. There are only a few extra components involved(7 passives and 1 NPN BJT), so it doesn't look too hard. I THINK this is virtually the same layout of the PropPlug itself. I've been wanting to have an extra PropPlug out in the shop where I do most of my hardware, instead of just inside at the PC. It sure would be nice, but I can't justify spending another $25(?) on a new PropPlug.

    I just may make one of these myself. Vaati, I'm going to make a few of these boards today. If you want the PCB to populate, instead of just a breakout board, I can send one of them. I don't want to cut in on Parallax' business too much, since they are very kind and have always been great to me, SO this would be more of a one time thing.
