Arduino due

[adafruit_support_rick]

Adding a delay is the correct way to debounce touches.

I am testing different sizes for #BUFFPIXEL when reading bitmaps, the Due has enough space. But only the value 20 gives the picture. The other values I tried gives just colored stripes. Is there a rule for changing the value of #BUFFPIXEL?

[adafruit_support_rick]

I just tried 20, 30, and 40. They all work. What values are you trying?

[PaulvZ]

I tried 60, 90, 120 and 180.

[adafruit_support_rick]

It works with 60 for me.

The problem with the larger numbers is this variable in bmpDraw

Code: Select all

 uint8_t  buffidx = sizeof(sdbuffer); // Current position in sdbuffer
 

It's an 8-bit unsigned integer. The reason BUFF PIXEL 90 doesn't work is that the size of sdbuffer becomes 270, which is too large for an 8-bit integer. Change buffidx to type uint16_t, and the larger BUFFPIXEL sizes will work.

However, the comment about it getting faster with larger BUFFPIXEL values is just wrong. I clock it as the same with 180 as it is with 20.

Hello ,
Why is this error - anyone can help me here - Im trying to solve this for 2 days now...

any tips ?

[adafruit_support_rick]

You have two different libraries that are defining TS_Point. Adafruit_FT6206 is one of them. What's the other one?
Please post your code.

Bit late but I think this is the trouble..

#ifndef Adafruit_FT6206_h
#define Adafruit_FT6206_h

..code..

#endif

is missing in Adafruit_FT6206.h

Good find. Fixed!
