Hi there, thanks for the hard work.

I've tested on my VIvoBook S13, img-capture, enroll works fine, but verify doesn't.
PID is 3128 so I added the following to the ID table:

{.udev_types = ELANSPI_UDEV_TYPES, .spi_acpi_id = "ELAN7001", .hid_id = {.vid = ELANSPI_TP_VID, .pid = 0x3128}, .driver_data = ELANSPI_NO_ROTATE},

I've tested with ELANSPI_180_ROTATE too, still cannot verify the enrolled fingerprint.

Oh by the way printdump.py can only work with 64x64 width and height. Does this mean the sensor is too small?

[mincrmatt12]

• Are you swiping your finger across the sensor (which is necessary for this driver)?
• Have you tried 90left/90right rotate options too?
• Does the image coming out of img_capture look reasonable? (see the notes here)
• Are you using the version of this driver currently in upstream libfprint? the latest version has moved there

If none of those things get it working, please try running the prototype in this repo and send the logs it outputs. As for printdump.py, it should work with arbitrary sizes? It should be called as printdump.py <file from the prototype> <path to output png before processing> <path to output png after basic image processing> <width> <height>, where the width and height should be logged by the prototype.

1. Yes
2. Okay so apparently the image is rotated 90 degrees so I tried using 90right
3. Hmm apparently it's reasonable but not good enough
4. Yes this was using the latest version

Still cannot verify the enrolled fingerprint. And apparently the fingerprint is 80x80.

====
you have a 80SC, if you haven't setup spidev with a large enough bufsiz _this will not work properly_

Alright well it looks like you're capturing images fine, but libfprint doesn't like them being so small. Sometimes it discards stuff close to the edge of the frame, so maybe try increasing the image_width in this file, something like:

--- a/libfprint/drivers/elanspi.c
+++ b/libfprint/drivers/elanspi.c
@@ -1325,7 +1325,7 @@ elanspi_fp_frame_stitch_and_submit (FpiDeviceElanSpi *self)
   g_autoptr(FpImage) img = NULL;
   g_autoptr(FpImage) scaled = NULL;
   struct fpi_frame_asmbl_ctx assembling_ctx = {
-    .image_width = (self->frame_width * 3) / 2,
+    .image_width = (self->frame_width * 3),
 
     .frame_width = self->frame_width,
     .frame_height = self->frame_height,

and see if that helps it any.
