Re: [Gc-linux-devel] HSP/Serial Port Question

[Rob R. <ro...@re...>]

The 2 serial ports are a quite standard SPI protocol. I've connected SD 
cards to it:

Speed is selectable between 1MHz and 27MHz. Should be easyly interfaced 
to chips like 4021, or 4094, A/D chips or a microcontroller with 
hardware slave interface like for example Atmel. ATMEGA. From there, you 
could hook up PS/2 KB/mouse, IR receiver, and so on. Or even better: see 
to program some CPLD to interface the sl811hs (or other) USB host 
controller efficiently.

For the HSP port: I think you could try 2 pcb's glued together to get 
the right thickness. Make just some contact fingers on them, and solder 
a 3rd pcb perpendicular to it. It's interface is (seen the signal names) 
compatible to standard SDRAM chips. Perhaps try to hook one up to it. No 
clue about RAS/CAS sizes and timing. Challenging!

If you need even more ideas, just ask :)
