[LinuxCNC/linuxcnc PR#630] Adds PORT pin type to hal. About GRBL HAL

Issue #630 | 状态: 已关闭 | 作者: curtdutt | 创建时间: 2019-08-08

A HAL port pin is a hal pin that acts as a real time one way byte oriented data stream An output port on any component may be connected to an input port on any other component via a signal. Data written on the output pin becomes accessible to the input pin. A HAL port signal may link only a single writer and a single reader. A port buffers data with a user definable buffer size.

Includes:
Documentation on how to use a port object.
a ctypes wrapper for the hal api (pyhal.py)
a test to exersice hal port code along with pyhal.py
changes to allow halcmd to understand and manipulate ports.

OK, let’s see how this goes.
It seems like a nice for the Mesa “stream” data type and the 7i73 LCD amongst other things.

Great thank you Andy,

and thanks to everyone else for their support and help over the last year.

I’ll get the laser code pull request set up next.

Looking at the buildbot waterfall plot: http://buildbot.linuxcnc.org/buildbot/waterfall it looks like only the RTAI builds failed. It is possible (likely, even) that the Travis builds don’t run on an RTAI kernel.

#7 – andypugh 于 2020-04-23

Minor thing, but builds are showing a warning:
http://buildbot.linuxcnc.org/buildbot/builders/1402.rip-wheezy-rtpreempt-i386/builds/4368/steps/compile/logs/warnings%20%285%29

(And they are not wrong)

#8 – andypugh 于 2021-03-10

Literally seconds of looking have not turnedup the sample code pull request. Did you create it?

#9 – curtdutt 于 2021-03-13

I will do my best to get the pull request together ASAP. Stay tuned.
