Question relating FTDI-Breakout fits for Propeller

heapdump

Hi all,

at first I am new here and just wanted to say hello

I am pretty new to this stuff, so with my first Propeller (which I am going to solder by myself on some proto-board) I accidentally ordered this FTDI-Breakout here:

https://github.com/watterott/FTDI-Breakout

While unboxing the board I noticed that it hasn't a RST pin like the PropPlug, but I found some option in SimpleIDE which says I can use DTR as reset. So will it work when I use DTR variant?

Thank you in advance and have a nice day!

I'm pretty sure that will work fine. Be sure to set 3.3v.

AFAIK, the RST line is driven by DTR in the prop-plug and it is using an FTDI chip so you don't need to set anything in the software. However the prop-plug is using a transistor to drive the RST line low, you may need to add that in your circuit. I found this thread with the schematic and informations that may be useful to you http://forums.parallax.com/discussion/155048/prop-plug-npn-transistor-value

That is true macca. But SimpleIDE, or more like the loader it uses, can use either. In fact there are other options for driving reset as used on the Raspberry Pi.

Put it this way. If using DTR does not work it's a bug that we have to campaign to get fixed as soon as possible.

Thanks for the fast reply! It works perfect if I set SimpleIDE to DTR mode, I guess this is the non inverted version of the RST or so...
