NEW INTERIM CODE RELEASE (VER 1.73) FOR DALF-1F MOTOR CONTROLLER!

This interim release, as an upgrade from version 1.71, contains one bugfix and a new feature. See the change list for details: changelist.txt. Contact Embedded Electronics if you are upgrading and would like a copy of the Ver 1.73 CD.

02/19/2008

The First Version of the Dalf Graphical User Interface (GUI Version 1.0.0) is now officially released and you may download the application and documentation (free!) from the downloads page. Just extract the files to a convenient directory on your hard drive and run setup.exe to install the application. If you later want to uninstall it, just use the Add/Remove feature in the control panel. You must have version 1.70 or later of the Dalf Firmware to use the GUI.

Announcing availability of Version 1.71 CD.

The CD contents and the Version 1.71 Release represent no additional functionality or bug fixes over the Version 1.70 Code Release but the 1.71 development files on the CD are compatible with Microchips latest Tool Suite (the 1.70 files are not). If you are doing embedded code development and using the latest Microchip tools you will need the 1.71 CD to extend or modify the factory firmware. Contact Embedded Electronics to obtain the CD.

NEW CODE RELEASE (VER 1.70) FOR DALF-1F MOTOR CONTROLLER!

This release incorporates the interim 1.62 changes as well as others. For full details as well as upgrade information visit the DOWNLOADS page and look at the upgrade and changelist documents.

Briefly - This release has a new operating mode "PotMix", a timeout feature for the Cmd Interfaces, improved closed loop motor synchronization for commands issued while the motor is running, and two bugfixes. In addition, this version of the firmware (or later) will be required for use with the GUI that will soon be available.

NEW INTERIM CODE RELEASE (VER 1.62) FOR DALF-1F MOTOR CONTROLLER!

This interim release features an improvement in motor synchronization when a closed loop command is issued during a closed loop movement. There is also a new command timeout feature that might be of interest to those of you communicating with the Dalf Board thru the API or I2C Interfaces.

Visit the DOWNLOADS page for updated documentation and code. A brief list of changes and information about upgrading your Dalf Firmware to the latest version is also available there.

NEW CODE RELEASE (VER 1.60) FOR DALF-1F MOTOR CONTROLLER!

This release features a couple of bug fixes and some major enhancements that make it suitable for the Windows GUI (Graphical User Interface) that is under development. The GUI will not work with earlier versions of the Dalf Firmware.

Visit the DOWNLOADS page for updated documentation and code. A brief list of changes and information about upgrading your Dalf Firmware to the latest version is also available there.

Two things to report:

1) Significant progress on the Windows GUI for the Dalf Motor Control Board. Setup, Open Loop Controls, and PID Tuning panels all work fine. I still have some additional features to implement and won't post the GUI until that is done, but stay tuned!

2) I have posted the first set of Application Notes. They can be downloaded from the DOWNLOADS page if you have the need.

Board Size: 4.60" x 3.65" The Dalf Motor Control Board was designed as a companion to a pair of OSMC Motor Drivers to control a pair of brushed PM DC motors, however it is usable with other motor drivers that use signed magnitude PWM controls. It also makes a wonderful development board for other applications because of the abundant IO and the use of standard software tools. The built-in firmware provides several different open and closed loop motor control methods. For closed loop applications it uses standard quadrature feedback from incremental encoders. Optionally, for suitable applications, analog position feedback may replace the optical encoders. Based on the PIC18F6722 running at 40MHz (10 MIPS), the hardware and firmware provide multiple user interfaces including: 3 channel RC with either tank or mixed modes, analog controls (center off or full range) using off board potentiometers, and serial command interfaces using the serial RS232 and I2C Busses. Closed loop PID using a Trapezoidal Generator is provided for both positional, and velocity controls. Adjustable slew rate is one of many features supported using non volatile storage for motor parameters. Voltage windows implemented using comparator circuitry and digitally adjustable pots provide very fast current limiting response when used with off board current sensors. Features are easily extensible using standard Microchip software tools, the supplied files (main.c + dalf.lib), and the 6-pin modular connector which is suitable for direct plug from the Microchip ICD2 Product. A Boot loader supports firmware upgrades over the serial link. Lots of unused I/O with signals accessible from the screw terminals and ribbon connectors. Ample headroom for additional code development in both FLASH and RAM memory. The +5V power supply supports a robust BEC for off board usage. Two I2C busses and two RS232 ports are routed to connectors. Detailed documentation including a voluminous Owner's Manual describing all features, and a somewhat less imposing, Getting Started Manual, are available for download.
