I'm pleased to announce the next release of the emc 2.2 series, emc
2.2.7. This version contains many bugfixes, including many enhancements
and bugfixes for the new "hostmot2" (hm2) family of drivers for the Mesa
PCI and parport cards such as 5i20 and 7i33.
For users of the hostmot2 family of drivers, some configuration changes
have been unavoidable:
* the hm2_5i20 driver has been renamed to hm2_pci to reflect the
support for additional cards including 5i22 and 5i23.
* stepgen timing parameters are "u32 ns" instead of "float seconds"
* stepgens now have a ".enable" pin which must be connected to
axis.#.amp-enable-out or other enabling signal
The new packages are now available in the package repositories. If you
have already installed an earlier 2.2.x version, this is available as an
update in the Ubuntu update manager. If you are still using 2.1.7 but
want to upgrade, instructions are here:

For information on how to upgrade from 2.2.x to 2.2.7 without using the
package manager, see

CVS users can get this release by checking out the RELEASE_2_2_7 tag.
Source tarballs are available from the package repository:

Many thanks to Seb Kuzminsky for his work on hostmot2 and particularly
for meeting a deadline I set at the last minute. Thanks also to Alex
Joni for building the hardy/i386 packages on short notice.
Changes in this release:
* pop up a message when the right kernel isn't running
* halcmd will now show an error message instead of segfaulting when
inadequate locked memory is available
* allow emc2-sim to be built on 8.04
* stepconf: fix "negative SCALE" problem reported by Christopher Purcell
* comp: fix bad C code generated from variable array declarations such as
'variable double output[8];'
* documentation improvments
* axis: "touch off" of rotary axis on metric machine
* hostmot2: Support all the PCI, PC/104-Plus, and EPP "Anything I/O"
boards: 5i20, 5i22, 5i23, 4i65, 4i68, and 7i43. PCI users should
switch from hm2_5i20 to hm2_pci driver.
* hostmot2 changes: Config changes required! pwmgen.scale now works as
advertised; stepgen timing params are "u32 ns" instead of "float
seconds"; and stepgens now have a .enable pin which needs setting.
* hostmot2 feature additions: Added PDM mode for pwmgen; PWM and PDM
frequency are now settable by the user; implemented stepgen maxaccel
and maxvel; support open-drain GPIOs; all GPIOs now have some
representation in HAL (though the ones used by module instances are
restricted); encoder improvements.
* Lots of hostmot2 bug fixes, mostly with pwmgen and stepgen. Thanks to
all the brave testers!
