<div class="moz-cite-prefix">Hi,<br>
Thanks for your reply<br>
In datasheet you linked are general information only.<br>
I found it earlier but I think it's more advertisement than
documentation.<br>
<br>
I used AES3500 driver instead of AES4000 but image is still pale.<br>
DATA_BUFLEN is set correctly. When I changed it to value for
aes3500, I got an error:<br>
sync:error [fp_dev_img_capture] unrecognised return code -5<br>
image capture failed, code -22<br>
<br>
FRAME_WIDTH is good too becouse fingerprint shape isn't broken.<br>
<br>
Earlier I got images clearly black, but now images are pale.<br>
I think it could be a problem with voltage or something related.<br>
Have you any idea which init_reqs could I manipulate to improve
quality?<br>

<div>The dimension params (DATA_BUFLEN or so) seems not right
from your image. Please have a look at aes3500.c and aes4000.c
from latest git repo:<br>

<div>Also, I've found the datasheet if you don't have already,
which looks a lot like aes3500's: </div>

Hi,<br>
I'm trying to add aes3400 support, but I get pale
image(example in attachment) and enroll fails.<br>
Have you any idea which parameters should I scale to improve
image quality?<br>
