Project Plan: Contractor's Progress, Status and Management Report. Monthly Progress Report.
Abstract
This monthly progress report contains information concerning the following hardware and software developments: (1) The design, layout, and routing of the Dyconex rigid flex board is almost complete. It has taken significantly longer than a standard board design because it is a new technology for ViA and we are learning how best to take advantage of it. The layout engineer has gone through two iterations already with the mechanical engineer to ensure that there are no interferences between parts on the top of the CPU board (WID201) and the bottom of the display board (WID203). Different designations are used, for clarity, for the different parts of what is really a single rigid flex board. We are expecting to release the layout to Dyconex next week and to receive the boards by early January. (2) A significant amount of work was done on establishing communication with the display on the CMD Eval Kit over the parallel interface. The CMD interface ASIC relies on a ready (RDY) pin to signal to the host processor when it can write into the display's frame buffer (integrated onto the ASIC). While this signal is supported by the SA1110 processor, it is not present on the SA1100 processor, which is what we are currently utilizing on the WID101 board for software development. Thus, we had to devise a different way to emulate the RDY function using a GPIO pin on the StrongARM. This effort was successful and we can not proceed to use these boards to develop a CMD CE driver.
