We have been having issues communicating with the DLP® LightCrafter™ Evaluation Module via the USB port, these issues are made more difficult by boot issues that make regular restarts of the device impossible.
Upon booting the device initiates the loading screen as usual and progresses to the final stage of this screen with the loading bar almost entirely full. It then hangs there without booting indefinitely. These issues have persisted since the device was first unboxed and happen with the device in any condition, even regularly occurring when the device is first booted after a weekend unused.
Some of the suggested work arounds on TI support forums have been attempted to no avail, including changing the Boot Mode as a form of hard reset. These boot issues are difficult to work with but are made more difficult still when attempting to fix the connectivity issues of the DMD.
We are attempting to use Python to program some functions for the DMD, to do this we are using the libUSB and pyUSB packages. The write/read commands in this package fail to work for our device even when using simplified code from the tutorial page of the pyUSB package.
When attempting to use the same code on a similar device from a fellow lab groups project these errors did not occur and we had no issues programming the DMD as we intended. When attempting this trial, we loaded the same code, through the same USB port and computer to a different device changing only the idProduct and idVendor numbers to that of the different device. We have confirmed we are using the correct idVendor number and idProduct number for our device as the command,
dev = usb.core.find()
returns TRUE when the device is connected and FALSE when the device is disconnected. The device also appears to experience connectivity issues with the Lightcrafter GUI software that is designed for the product, the software will at times not be able to find and connect to the device for long periods.
From this it appears that the connectivity issues are sourced from the device itself, whether they are related to the boot issues is unclear but together these two issues make the device currently unusable for our intended purpose.
Any help with these issues would be greatly appreciated as we are currently still planning to implement the product into our project.
Thanks in advance.
