Date: Wed, 2 Jan 2002 15:11:56 -0000 Hi guys I have a background in programming, but little in the way of electronics, and as such, I have a few questions about the project. Forgive me if my high-level mindset misses the mark too often. o Are the character font sizes fixed on the LCDs or are they variable? o What is the quality of the gcc generated code? With such a small footprint available, would assembler be a better bet? I've no idea, just thinking aloud here. o Are there any (tiny or otherwise) OSs already written that we could obtain/use/modify? If there are, would such an approach be sensible? After all, an OS typically provides raw services for client applications, whereas we would have just a single application, no? Is this right, or can anyone envisage a need for scheduling/multiprocessing? Does this require CPU support? o Is there any argument for the immediate development of high-level components of prospective applications before the low-level interfaces are completed? I know that this is the hacker mentality coming to the fore :) but application developers could make progress on core features (music control, playlist manipulation, etc) independently of the work being carried out on the metal itself. o Is the CPU capable of decoding other music formats in real-time, or is dedicated chip support necessary for this? o Which low-level components need developing before we can begin to replace the archos-provided code? I know the MP3 en/decoding is done on chip - do any more of these come for 'free'? o USB driver code? o IDE controller code? o LCD driver code (exciting to see the preliminary work done here) o MP3 decoding drivers? an aside: o Is it possible to write code to dump the *rom* firmware to a file? If so, would this be directly usable as (or convertable into) a mod file for others? I'm thinking about newer models with firmware on rom (rather than shipped as updates). regards, wavey --------------------------------------------------------------------------- LATEST NEWS FROM VALTECH CRM - Delivering on expectations John Plumpton, Senior Business Consultant at Valtech, has written an article for CommsDealer in which he outlines how a properly structured CRM solution can provide much-needed competitive advantage.
