Kurt,
I downloaded your stuff, loaded and compiled the graphicstest example, and uploaded it to the Edison.
But same results as before, just the backlight, although the Edison was churning thru the code and outputting to the console.
All the diags at the start came back 0.
Note, I used jumperwires to hook up the Seeed which allowed me to remap a few pins:
| Adafruit | Seeed |
| Pin 4 | SD CS | SD CS | |
| Pin 5 | -- | TFT CS Pin 10 | |
| Pin 6 | -- | TFT DC Pin 9 | |
| Pin 7 | -- | -- | |
| Pin 8 | -- | -- | |
| Pin 9 | TFT DC | -- | Pin 6 |
| Pin 10 | TFT CS | -- | Pin 5 |
| Pin 11 | MOSI | MOSI | |
| Pin 12 | MISO | MISO | |
| Pin 13 | SCLK | SCLK |
You did get the graphicstest to work in Arduino (and it made pictures), right?
