Update:
 
With the addition of the latest revisions to CGM, we have several test units running stable for several days using the latest firmware, with error rates less than .001%.
 
We are nearing completion of the USB bootloader, and have discovered a potentially serious issue. We believe we will be successful in porting a bootloader for use with the onboard PIC16 controller, but may not be able to install it and the board firmware at the same time due to memory constraints. The PIC16 has 16k of available memory. Our calculations estimate the finished bootloader will consume roughly 4k of the available memory, which will not leave enough room for the firmware in its present state. We have begun removing unused portions of the firmware code to reduce its size, and will be testing pro versions of the Microchip compiler to further reduce its size, but it is currently unclear as to whether or not this will be enough.
 
While we will continue to do everything in our power to deliver full functionality to the units, our options are limited by the design, and there is a real possibility the hardware simply will not be able to support a USB bootloader. As such, if the ability to update the firmware via usb or chain the units via the I2C connector is not a priority for you, the best option at this point may be to request shipment of the units as-is.
 
As before, to request your units be shipped as-is, without the ability to update the firmware via USB, please ensure the shipping address provided on your liquidsyndesigns.com account is correct, and reply to this email with the subject “Please ship my units without USB bootloader”.
 
Hosting:
 
We have begun setting up hosting for those customers who have purchased this service. Several modifications were necessary due to the unfinished I2C functionality, as well as the lack of individually serialized units. With the arrival of additional hardware and successful testing of the latest firmware, we are now building out the cluster. We have had to modify our original hosting design completely, which is now complete. Additional information and instructions will be sent to those with hosted units.
 
Assembly refunds:
 
Many of you are still waiting for information regarding the assembly refund process. We understand the wait is aggravating, and appreciate your patience in this matter. Our resources are finite, and the work load for this project has increased substantially due to reasons outside our control. We will be publishing more information when we are able, and can assure you the solution will be as fair as possible. You will not be punished for our lack of timely response in this matter.
