Hi Tom

I tried the CCW / CW option but no response.  Not sure if I set it correctly.  I added 48 to the output channel number.  For instance channel0 I set output to 48.

Using a led on the output I'm not seeing anything happen. 

With std step/dir and quad I can see the step test led dim when pulses are outputting, and the direction led turn on and off with direction changes.  In this case there is nothing.

Thanks Gerald

Oops.. Ok now it works.  Had to add 56 (8 + 48) because my board only works in LVTTL mode.  G

PS  re- "Update FTDI USB Drivers to Version 2.12.0.0"

What does this mean in practice?  Any advantage in changing driver, given the old one still seems to work?

I also noticed the install routine seems bit more involved - ie. having to check "load VCP" which I've never done before.  Is this a new requirement and can you outline what it means?

Thanks Gerald

Hi Gerald,

I'm not sure exactly.  The newer FTDI drivers have a couple years of fixes.  I thought the older drivers sometimes had issues after Windows sleeping or hibernation on some systems.  But nothing repeatable enough that I could test.  I was hoping that the newer drivers might fix those issues. I'm not able to measure any throughput difference.

The drivers have always had an option for VCP (Virtual COM Port Driver) that we don't use and doesn't need to be loaded and shouldn't be needed.  Not sure where you are seeing that.

Regards
TK

Re VCP.  HI Tom in your latest driver install instructions, you describe checking the VCP box.  I've never done this and not sure what it does - maybe it allows changing the COM port number?

If a PC goes to sleep while connected it usually means restarting, so I set the computer to never sleep...

Hi Gerald,

We have a pdf file in our on-line help on how to load the FTDI Virtual Com Port Driver if you need it for some reason.  Most Users would not.  Our Apps or Libraries use a DLL that communicates with the USB driver to send data directly to KFLOP.  In this case a COM port is not involved at all.  Certain users are running or writing applications that are not able (or have difficulty) using our DLL Libraries.  Some Visual Basic Users fall into that category.  They don't know how to interface to an external DLL.  But they do know how to send text out a COM Port.  The Virtual Com Port appears to the Windows Application as if it was a Serial Com Port.  It is simple to just open a COM port, set the (phoney) baud rate, and send/receive character streams.  None of our KMotion Libraries with the GCode Interpreter, Trajectory Planner, and so forth will be available when doing this.  But it is possible to send Low Level Console Script Commands to KFLOP.  The VCP doesn't usually have the same throughput as the direct DLL interface.

The new drivers may allow coming back awake from a sleep more gracefully.

HTH

Hi thanks Tom. 

I assume when you refer to the dll you mean the .net interface?  I am still using KM_viaVB.dll which works well enough.  I have added all the motor output options now.  So individual axes can be assigned stp/dir, ccw/cw or quad.  They can also be repatched to swap axis outputs and also run as slave axes.  It all works nicely.  :)
