Re: CANopen

Hi, I was able to port the CANopen source code from the servo amp manufacturer Copley Controls. The source code is available to users of their products. I would imagine if you purchase a servo amp to test the code you would be able to get access. I don't doubt my company would allow access to my cod...

Re: kermit

Hi SeeCWriter,
I have a project to implement OpenBMIP version 9.4 on the Netburner. It looks like the requirement for kermit is still around. Did you ever find and implementation that you were able to port? Is there any way we could work out a license for your code?

Thanks,

Carlos

Re: Fast sin/cos/tan math lib approximation recommendation

Hi Paul, Thanks for your response. I primarily need sin() & cos(), although I also have a few instances of the atan2() function. I need a precision to 0.001 deg. I can use symmetry in the solution to reduce the lookup table size by a factor of 4. I should only need a table for [0 - pi/2], with t...

Fast sin/cos/tan math lib approximation recommendation

Hello, I have an application on the MOD5441X that is using quite a bit of cpu time calling the math library functions sin(), cos() & tan(). I would like to find out if anyone has found a faster math library. I am willing to accept a drop in precision for an increase in speed. I need better than ...

Problem enabling UCOS_TIME lib in predef.h NNDK 2.7.0

Hello,

I would like to add the task utilization library functions available when the predef.h definition 'UCOS_TIME' is enabled. However rebuilding the NNDK 2.7.0 system files is unsuccessful and returns the very cryptic error:

make: *** [ucosmcfc.o] Error 1

Thanks,

Carlos

PWM input capture to measure fan/pump speed

Hi, I would like to use the MOD545515 PWM input capture capability. I'm looking for an application note that or other reference that may already have software for this feature. The idea is to use the PWM I/O pins to measure the period and pulse of a set of input signals. The input signals are from a...

Re: MOD54415 External IRQ example

The include file and associated library functions are specific to the MOD5282 module. I have the following: c:\nburn\MOD5282\include\pin_irq.h c:\nburn\MOD5282\system\pin_irq.cpp It looks like a new set of library functions for the MOD5441X is required to implement the examples. I have both modules,...

Re: GPIB interface solution

Chris, Tod & rhopf1, Thanks for your replies. At this point I think the best solution I've found is using an Ethernet to GPIB adapter. The project has some tight volume constraints in that I have to reuse the same control box. However it looks like the Ethernet to GPIB adapter from Prologix (htt...
