hi About 7I43, i am interesting in how many I/O chanlels with 8 AC servo motors?
thanks aram > I'm pleased to announce version 0.1 of m7i43_hm2, a HAL driver for the > new Mesa Electronics 7i43 board with the HostMot2 firmware (short for > Host Motion Control 2). Information about the 7i43 is available at > <http://mesanet.com/>, click on "MOTION CONTROL" on the left and scroll > down to the 7i43 section. > > The 7i43 plugs in to a PC's parallel port. It has an FPGA with 200K or > 400K gates and 48 I/O pins (in addition to the parallel port). It is > powered by 5V from a USB port or from an external power supply (the USB > port is used for power only, all communication is over the parallel > port, in EPP mode). > > The HostMot2 firmware is highly flexible, and can include quadrature > decoders, PWM generators, and step/dir generators, in addition to > gpios. Full VHDL source code for the firmware is included. Also > included are several precompiled firmware binaries supporting 4 servos > and 4 steppers, or 8 servos, on a single 7i43 board. > > The driver is very immature. Lots of firmware features are currently > unsupported. I'm aiming for full support in the next few months. I am > trying to be compliant with the Canonical Device Interfaces as far as > possible. > > The driver can currently configure the 7i43's FPGA with the HostMot2 > firmware, and has very basic support for the encoder and pwmgen > features. 4 channel servo control is possible at 4 KHz (read the > encoders from the board, run the pid software component, and update the > pwmgens on the board). > > I am grateful to Peter Wallace at Mesa Electronics for his fantastic > support of this project. > > > Comments and suggestions are welcome, and I'm seeking brave testers! > > > -- > Sebastian Kuzminsky > Immanentize the Eschaton > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Microsoft > Defy all challenges.
