There's a thread on the forum now
But since I can't post there yet...
Note that there's a comment on the page for the smaller display that links to a datasheet for a module using the HD66782. It contains the initialization sequence.
It's interesting that the connectors for the main and sub displays of these sparkfun modules are identical, suggesting that the operating modes are very similiar.
Current internet digging doesn't look good. The LCD driver part of Renesas was split off earlier this year. The new website is content free.
The only info I've found on the HD66790 so far looks bad. It's described as a RAM less controller and the system example shows it connected to a CPU via a "display controller processor" and external ram for the display.
Doesn't look like the easiest setup to replicate with an embedded micro!
No public wish lists :(
