Category: HAL
Thanks for your discussion. A few minutes ago I got my simple concept breadboard running with adaptive feed so that I can throw a physical switch that is attached to a GPIO pin on the Rpi5 and the trajectory backs up. As is typical, once I got some of the basic ideas of the HAL programming (thanks A METRIC TON to swolebro and his excellent tutorials!), I has able to hack a HAL file together. I now need to think more about the system architecture which relates to your discussion. Am I missing something or does the linuxCNC documentation lack one key element that is critical for the newbie: there are precious few if any examples of HAL command syntax in the documentation...not the case for most languages. I think including a few examples per command would greatly lower the learning curve.
