Re: RepRap with XMOS

… Yes I will be tackling acceleration and even more ambitious things such as arcs, both of which should work with my drivers, the Xcore examples and even the Trinamic drivers. I am hoping this can be done at a high level but obviously each driver might exhibit somewhat different dynamic features un...

Re: RepRap with XMOS

Hi Dan, I have quickly checked the source code. I did find some stepper driver. But I did not find any kind of motion control (acceleration/decelration/ axis coordination). Is that correct or did I jus not look good enough? Since that will be one of the most important building blocks of an reprap. I...

Re: RepRap with XMOS

Hi Dan, thanks for the hint. Yes I was aware that the project exists. But I was not aware what is in this project. I want to use the Trinamic chips for several reason: Ease of use. I know how they work and their features. And I like them. So this should be easy to do. I really do not have the slight...

Re: RepRap with XMOS

No problem Folknology, I think we are working on the same problem, just starting at different ends ;) I still don't know if it will be XC-2 or XC-1 compatible. But most probably both. I think I will use the modular approach of the current projects on github. So that you got some serial communication...

Re: Using correct debug settings?

This is from the ap_led_tile on Mac OS X 10.7.2 wtih the 11.2 tools: https://github.com/xcore/sw_led_tile_controller https://github.com/xcore/sw_led_tile_controller You can check the source there on github. And yes, it is a multithreaded application. Perhaps I have not correctly switched to the thre...

Re: RepRap with XMOS

To hijack this thread again I want to point out what my intentions with the reprap are: I am a big fan of the Trinamic stepper drivers and reprap. As said befor the guys from Trinamic are friends of mine - so I am a bit biased, please excuse that. I am planning to use an XC-1 or XC-2 kit and add a c...

Re: Using correct debug settings?

Hmm,

as you can see above I use -O0 & -g for my debugging version. It is very strange since the variable show up in the 'variables' tab in XDE. But they do not work as wathc expressions nor can I get their value as tool tip. Something strange with my installation?

Thanks for your help.

Re: Strange Problem with sc_ethernet two port

Ok,

mystery of inuchar is solved - it reads from the channel, I found this post explaining it.
So obviously the channel is not there/not ready, will investigate it further.

Re: New Simple Robotics/Motor control dev board

Sure I think this kind of separation is possible but there are also complications. … But the dynamics of steppers and DC motors are rather different and that will effect planning and acceleration for example, so it may not be completely transparent as an abstraction. regards Al Yes, there will be m...
