Difference (from prior major revision) (no other diffs)

Changed: 3c3
HostMot2 is an FPGA configuration developed by [Mesa Electronics] for their line of "Anything I/O" motion control cards. The firmware is open source, portable and flexible. It can be configured (at compile-time) with zero or more instances of each of several Modules: encoders (quadrature counters), PWM generators, and step/dir generators. The firmware can be configured (at run-time) to connect each of these instances to pins on the boards' I/O headers. I/O pins not driven by a Module instance revert to general-purpose bi-directional digital I/O.

Several pre-compiled HostMot2 firmware binaries are available for the different Anything I/O boards. (This list may be incomplete, check the EMC distribution and Mesa's web site for more up-to-date firmware lists.)

Using HostMot2 with EMC



Using HostMot2 with LinuxCNC




Changed: 26c26
The EMC support for the HostMot2 firmware is split into a generic driver called "hostmot2" and two low-level I/O drivers for the Anything I/O boards. The low-level I/O drivers are "hm2_7i43" and "hm2_pci" (for all the PCI- and PC-104/Plus?-based AnyIO? boards). The hostmot2 driver must be loaded first, using a HAL command like this:

The hostmot2 driver by itself does nothing, it needs access to actual boards running the HostMot2 firmware. The low-level I/O drivers provide this access. The low-level I/O drivers are loaded with commands like this:
