Re: Slicekit Hardware Manual

Folknology, Thanks for the tips. We have actually moved the card to another slot, and everything is working. We have tested the Triangle port on two cards (rev 1V2) with the same results. Every non-muxed pin that I have tried works properly. I am doing my testing with an oscilloscope, and nothing pl...

Re: Slicekit Hardware Manual

Correction: the 74CBTLV3257 is an analog multiplexer, so it should be possible to use X0D0_EXT and X0D11_EXT bidirectionally.

Re: Slicekit Hardware Manual

Folknology, thanks for the link, but the advisory was not for this particular issue. I looked at the schematics, and it seems that U6 has OE_N hardwired low. This means that X0D0_EXT and X0D11_EXT can be used as outputs if pin 1 of U6 (S) is held low. I do not see how either of these pins can be use...

Re: Slicekit Hardware Manual

Oops. That was a silly error. I have changed the Makefile and recompiled the project, but the A and D ports are still being held down by the MUX chip. I get the same result when using SLICEKIT-L2 as the target. The Makefile is now: TARGET = SLICEKIT-L2 APP_NAME = app_Brian_Gordon USED_MODULES = modu...

Re: Slicekit Hardware Manual

TSC, I have followed your advice, but the A and D ports are still being held down by the outputs of the MUX chip. This is the active content of my Makefile: TARGET = XK-SK-L2 USED_MODULES = module_slicekit_support XCC_FLAGS_Debug = -g -O0 -Wcodes -Xmapper -Wcodes XCC_FLAGS_Release = -g -O3 -Wcodes -...

Re: Slicekit Hardware Manual

Thanks for the correct and informative reply. This is what happens when I do not read every page carefully. I still think it would be nice to flag the afflicted pins in the tables with a note to read the XS1-L16 boot section. It looks like you have given me a simple solution to my colleague's problem.

Slicekit Hardware Manual

A colleague of mine just built a custom board to plug into the TRIANGLE slot of a Slicekit. The one bit ports he selected (P1A0 and P1D0) did not function as expected, and the schematic shows that these ports are connected to the output of a multiplexer (U6). It looks like the STAR slot has a simila...

Are there any plans for an XC-2 replacement?

<t>Are there any plans for an XC-2 'replacement'?  Something with a newer processor and more I/O would be very useful.  The current offerings which support Ethernet are not very compact, and not well suited to embedding in instrumentation.  It would be really great if there was a way of programming ...

Re: New Combinable and Distributable task features

This may sound like a silly question, but where can I find documentation on the XC2 compiler? Also, when I just tried to download the command line tools for linux, I could not find them. Do I have to download xTIMEcomposer studio and find where the command line tools are hidden in the download?
