The combination of an ARMmite or ARMexpress combined with a Vinculum Vdrive2 is very powerful. The ARMmite BASIC compiler or the pre-configured ANSI C compiler makes it a snap to integrate serial device to solve your control problem. The first step was adapt the cable for the ARMmite, schematic attached.
Next was to mount the mating connector on the ARMmite, alligned to the alternate holes
for IO(8) through IO(12), and to make the ground and power connections.
This was originally done with a rev 2 board, but the rev 3 can be used as well, with a
5V regulated supply
The simplest method to control the Vdrive, is to use the serial method, which is the default jumper setting as shipped from the factory. This jumper setting places the jumper between the 2 pins furthest from the 7 wires used to connect to the Vdrive.
Now the control program itself, consists of making sure the Vdrive is in sync with the ARMmite, and then sending commands to delete any previous version of the log file, to open a log file, write some lines to the file, and then close the log file. Vdrive include file and BASIC test program source
