This Sparkfun display is the one that we have, but we have not
yet even talked to the card. Other things have taken priority.
The card is about 2 1/8" by 1 9/32" so it would fit in the SOC Project box.
However, getting to the micro SD card might be a bit difficult.
At $25, it seems like it MIGHT be a good choice to support Logging.
Apparently Sparkfun has two libraries for this display:
1. Write to and Manipulate the display (but we would need to turn
the information 90 degrees for our landscape use).
2. SD card support, to read/write files to a Fat 32 file system.
Tasks:
1. So, first is to talk to the board.
2. Measure byte rate (to SD card) to see if it is fast enough to Log
(we need about 140k bytes per second, I think)
3. Write to screen in landscape mode
4. Write binary Fat32 file to SC card.

Yes, we are working on usig a display that includes a micro-SD card.
When we are able to write a file to that card, we will be able
to do one-bus CAN logging right in the SOC-Meter.
Exactly - we just need to find the right display. I had looked at some of them - either the display was too small or some other problem.
Found anything good ?
Hmmm ... may be this ...

"1.8" 18-bit color TFT LCD display with microSD card breakout - ST7735R"
It is about the same size as 6610, has TFT and comes with microSD.
This looks like better value than 6610 !
