2.8" TFT w/ Capacitive Touchscreen Unknown Driver Chip 1010

Post by terryb »

Hi,

I'm using the later version of the 2.8" touchscreen shield. The one with a micro SD slot. I get "unknown driver chip 1010" when trying out the example sketch. As per the posts in this thread I tried using the old library but that didn't work. From another post I got a suggestion to try hard-coding identifier = 0x7575 and it seemed to work. I realized that 0x7575 wouldn't be the right value for this shield which uses the ILI9341. I forced it to use that and I get the following output but the TFT screen remains all white. (blank). What should I do?

Using Adafruit 2.8" TFT Arduino Shield Pinout
TFT size is 240x320
Found ILI9341 LCD driver
Benchmark Time (microseconds)
Screen fill 450504
Text 317028
Lines 3161696
Horiz/Vert Lines 64980
Rectangles (outline) 52912
Rectangles (filled) 1264036
Circles (filled) 894756
Circles (outline) 1380436
Triangles (outline) 1002936
Triangles (filled) 1046300
Rounded rects (outline) 441336
Rounded rects (filled) 1605892
Done!

You're using the Adafruit_ILI9341 library? Or are you using the old Adafruit_TFTLCD library?

If you're using Adafruit_ILI9341, then it sounds like a defective screen. Please email [email protected] with a link to this thread for a replacement display

It worked! I was using the Adafruit_TFTLCD library. I didn't know there was a library specifically for the ILI9341. I can finally get on with my project. Thank you!
