There were two places in the code that you will find the code segment. =
The one
place is for initial settings, and the other is when there is a problem =
for
recovery. (I think)

I think, yes, one is to try the values 4, ... 32 until one works. At =
least that
is what I understood to Allesandro's last suggestion.

This is what Allesandro mailed in the past:

-------------

A possible solution is changing=20

            | BT848_GPIO_DMA_CTL_PKTP_4   /* and do DMA as soon as =
possible */
            | BT848_GPIO_DMA_CTL_PLTP1_4
            | BT848_GPIO_DMA_CTL_PLTP23_4;

into three _8 _16 or _32 (main.c, line 934 more or less -- and 530
if you want, but it's much less important).

-------------

On my system I still get messages at times, (which I comment out) but my =
screen
interference is now gone.

I'm sure Allesandro will answer this more fully when he gets back from =
his
(fatherly?) duties... -grin-
