Data transfer LinuxCNC to / from custom board - Solved

Category: Advanced Configuration

You seem to have a lot going on there.
First thing I would suggest is to simplify things by choosing which jog method you actually want to use and then test this method in the 'Halshow' tool without all the connections in your hal.
For example this situation should jog the x-axis:

 

Alternatively this should also jog your x axis:
 


Also, posting your hal and ini files might give us a better idea of what you have going on.

Hi Becksvill,

Thank you !

I made a short video how it runs on the boomerang gcode file, i enabled using the scurve velocity ends in the kernel code :


I think it run's quite good for a first test.

I removed the boomerang preview (released opencascade memory), to get the gui more responsive. I made a button for this.
During screen recording, the gui even becomes slower.

Removing the boomerang preview works great, however i am thinking when running huge files, to show only a certain portion of the
gcode file.
Like 100 lines before and 100 lines after the current executed gcode line.

Furthermore i can optimize the opencascade memory, to show a memory efficient shape, like a memory efficient linestrip over the path,
this then for huge files like >10000 lines.

I was just throwing it out there.
In all honesty it really doesn't go with the ethos of your project. From the beginning you wanted to stay away from softcores.
Just while I have it on my mind;

i have no problem with discarding initial concepts if it brings an advantage, unfortunately i still see disadvantages in softcore.

reg [5:0] initialization_progress = 6'b000000;

More code......

[code]end else if (state == STATE_INITIALIZING) begin
spi_clk <= 1'b0;
state <= STATE_SENDING_COMMAND;
initialization_progress <= initialization_progress + 6'b000001;
spi_chip_select_n <= 1'b0;
spi_clock_count <= 10'd0;
is_busy <= 1'b1;

case (initialization_progress)
// TODO: Perhaps add software reset here?

0: current_instruction <= SET_PHY_MODE;

// Set our MAC address
1: current_instruction <= {SET_MAC_ADDRESS_BYTE_0, MAC_ADDR[47:40]};
2: current_instruction <= {SET_MAC_ADDRESS_BYTE_1, MAC_ADDR[39:32]};
3: current_instruction <= {SET_MAC_ADDRESS_BYTE_2, MAC_ADDR[31:24]};
4: current_instruction <= {SET_MAC_ADDRESS_BYTE_3, MAC_ADDR[23:16]};
5: current_instruction <= {SET_MAC_ADDRESS_BYTE_4, MAC_ADDR[15:8]};
6: current_instruction <= {SET_MAC_ADDRESS_BYTE_5, MAC_ADDR[7:0]};

Am I right in thinking that SET_PHY_MODE is never acted on as initialization_progress is incremented before the case stanza ?
[/code]


you must not look at it as a programmer :)

this is verilog logic, not serial programming.
Everything runs in parallel

that:
initialization_progress <= initialization_progress + 6'b000001;
and this:
case (initialization_progress)
is executed at the same time and therefore the value in the 'case' is still 0 and only in the next 'always
@(posedge clk) begin' is it 1

verilog can be a real brainfuck :)

Thanks Scottlaird,
Please receive xml file exported from lcec_configgen command.
I do not think I can use content from this file :)
 

File Attachment:

File Name: tsino-lcec...ggen.xml
File Size:17 KB

I have idea to use modules in one CiA402 as this file
I am not sure it is the best optimization, please advise.

In other hand, can you share your xml of 2 and 6 axis device ?.
Thank you.

Can you get me started on using LinuxCNC on a non-traditional kinematic mechanis

Category: General LinuxCNC Questions

Custom kinematics written in C can be found in 'src/emc/kinematics'
github.com/LinuxCNC/linuxcnc/tree/master/src/emc/kinematics

Generally I would suggest to write custom kinematics as a component (.comp). Unless of course you have a compelling reason to use C (and know it well enough). See examples like github.com/LinuxCNC/linuxcnc/blob/master...onents/millturn.comp
or the more complex
github.com/LinuxCNC/linuxcnc/blob/master.../xyzab_tdr_kins.comp

For the latter there is a paper with documentation:
forum.linuxcnc.org/10-advanced-configura...mill?start=80#263694

[edit]
to compile and install a custom kinematic file:
halcompile --install <path/your_component.comp>

(prepend 'sudo' if you are on a package install):
