Insufficient memory for signal/pin

You might have to edit this entry and recompile:

github.com/LinuxCNC/linuxcnc/blob/master.../hal/hal_priv.h#L331

Should I modify the HAL KEY or the HAL_SIZE? And which value should I put to modify one of this, especially if it is the HAL key which need to be modified.

It would be the size, you certainly don't want to be changing the key.

Is there any possibility of reducing the pin count by modifying the loadrt parameters of some components?

At the moment I am still in the development phase, so I am still creating lots of pins and would like to be able to extend the memory. Surely will do a bit of cleaning once I get a more finalized version of the hal configuration I will eventually used. But so far, all components are used and I can hardly reduce the amount of pins.

If you are using Mesa cards then you can turn off unused stepgens and encoders (for example).

But, other than that, no, if you load the components you get the pins.

However, I have never heard of anyone else runnoing out of HAL memory (recently) and so I wonder if there are things that could be done more efficiently, possibly with some simple custom components.

Hi,

thanks for your advice. I managed to achieve some additional function for my project, by removing some other hal components or their pins function that were not used. Nevertheless the project has become bigger and I am at the point where I have removed all non used component pins. So here we go, I need all the hal elements loaded on my project but if I add one additional pin to any component I got the Hal insufficient memory error message.

I guess I have now to increase the memory for the hal. Can you indicate me how to do that more precisely from the file you have indicated earlier, especially to be able to recompile only the required file related to hal without the compiling everything for linuxcnc.

Thank you,

Nicolas
