Function to send templates from your controller to the sensor #36

Open ricarduscat opened 6 years ago

ricarduscat commented 6 years ago 
uint8_t Adafruit_Fingerprint::downloadModel(uint16_t id, uint8_t packet_1[], uint8_t packet_2[], uint8_t slot) {
  uint8_t packet[] = {FINGERPRINT_DOWNLOAD, slot};
  writePacket(theAddress, FINGERPRINT_COMMANDPACKET, sizeof(packet)+2, packet);
  uint8_t len = getReply(recvPacket);

  if ((len != 1) && (recvPacket[0] != FINGERPRINT_ACKPACKET))
   return -1;
  if (recvPacket[1] == 0x00) {
    writePacket(theAddress, FINGERPRINT_DATAPACKET, 130, packet_1);
    writePacket(theAddress, FINGERPRINT_DATAPACKET, 130, packet_2);
    return recvPacket[1];
  } else {
    return recvPacket[1];
  }
}

I made this with the latest version of the code. I need to put templates back to the sensor when I free the memory. The documention of the sensor says it's allowed, but not implemented in the library. This does not work, it will be fine to improve the library.

marianodato commented 6 years ago

This function worked for you? Did you find another solution?

ricarduscat commented 6 years ago

Yes, but I had to touch the fingerprint sensor packet size to adapt it to the datapackets I was sending

marianodato commented 6 years ago

@ricarduscat could you explain how to do that?

milindrc commented 5 years ago

@ricarduscat please explain the parameter you need to pass to this function.

sand007man commented 5 years ago

i am able to enroll ,search fingerprint but when i load show_fingperprint _template it is showing some "??" values in the serial monitor . even small help will be greatly appreciated . I am using this fingerprint with node_mcu esp 12e...i feel its something related to memory buffer !!

hanifizzudinrahman commented 5 years ago

recvPacket

what is "recvPacket"? the last packet, or what?

Try using larger buffer for the software serial something like SoftwareSerial mySerial(D7, D8, false, 1024);

default is 64bytes packages of template are 128bytes+11bytes maybe it got overwritten

@ricarduscat If possible can you please expand on this code ?(What are the parameters..etc). Is there any other way where I can load the templates from one sensor to other sensor. BTW I am using R307.

adityadate1997 commented 4 years ago

Sir, we have downloaded the fingerprint template data from the module r305 using the show_finger_template library. It gives us an array of size 512....we want to compare this stored array on server side. What exactly do we need to do? We tried comparing the array byte by byte but it does not give proper output. Can you guide us on how to match these templates sir.

Thank you.

Hello adityadate1997,

You need to store the template into your fingerprint sensor and compare it with the fingerprint that the sensor is receiving from the user. Probably, you will need to store templates from a database to the database of the sensor to check the fingerprint that your sensor has received and compare it with the fingerprints of the database.

Good luck

shreeramkulkarni commented 4 years ago

@rodrigotabsan Are you able to get the templates out from the sensor and store those templates into another sensor's flash memory? If so what sensor are you using ? I'm also trying to achieve the same thing using NodeMCU and R307.

rodrigotabsan commented 4 years ago

@shreeramk1998 I didn't try that. I can't get the fingerprint template I have stored in an external database to match the one I put on the sensor. I'm not sure this can be done... I've been working on this for several months with no results.

Hello This is the 3-finger pattern output stored in the module I have saved these templates in the server database. Can I restore these templates to another module (fingerprint) and be usable?

Do it with example code "Upload", so the template will move to another module fingerprint

mlinaje commented 2 years ago

After reading all the datasheets I have found. Does someone knows if the template/signature of the fingerprint format follows some kind of standard such as ISO, ANSI,...? Thanks in advance!

Dygear commented 2 years ago

So, I read the datasheet, looks like this uses the DownImage function documented here on page 19. You can also upload an image to the sensor with UpImage (found on page 18.)

The images themselves and the formatting used are documented on page 8 (under the title 4.1.1 Image Buffer) says that the captured images are 256x288 pixels in size.

When uploading or downloading images though the UART port, in order to speed up the speed, only the upper four bits of the pixel byte are used that is, 16-level grayscale is used, and each byte represents two pixels (the high four bits are one pixel, and the low four bits are the same. A pixel in the next adjacent column of the row, that is to pixels are combined into one byte and transmitted). Since the image is16 grayscale levels, uploaded to PC When displaying (corresponding to BMP format), the grayscale should be expanded (expanded to 256 grayscale, i.e. 8bit bitmap format.) Transmission though the USB port is a full 8-bit pixel, that is, 256 gray levels.

What I think is needed is for the image to tz function Img2Tz page 19 again, after capturing / sending two images with that function it stores the first image in CharBuffer1 and CharBuffer2. Then you can run the RegModel function (page 20) that takes the contents of CharBuffer1 and CharBuffer1 and tries to make a template model out of it.

On page 21 it looks like you can straight up take the template model (they are now calling it characteristics) and "upload" that to the host computer. On page 21 again it has the DownChar function that allows you to download into the characestirics buffers and then you can save them into the flash memory with the store function call.

I think the only functions you really need are the UpChar, DownChar and Store functions in order to sync a database across multiple devices and have it return the same position ID. If they became out of sync you can always delete the database and copy one fingerprint reader to another using the Empty function (documented on page 24).

Edit: I call all of these functions, but really they are called "Instructions" in the document parlance.

I was also in need of such functionalities (to read, save and write back template data to similar sensor models) and thus came up with an update to the existing library. @Dygear what you said is correct. I have a pull request pending about this. Please checkout my repository about this update. Also checkout the changes I've made.

However, keep in mind that writing template data from one model to another won't serve the purpose as different sensor models might use different template matching algorithms.

Hope I was able to help!

These are actually hex values. You need to put '0x' before the hex values. Like this: 0xFE

@Gitare420 check this repo again after 4hrs (busy with other stuffs) , I will update the get template example to show hex values with '0x'. I know it's hard to put '0x' before 512 values.

Then I used the write function and it uploaded without problems, but when using the fingerprint scheme to read it tells me

"Image taken Image converted Did not find a match"

Did I do something wrong?

AsifKhan991 commented 2 years ago

@Gitare420 Did you use the same sensor for reading the template from and writing to back it? What is the model pf the sensor? Also what id you enrolled against?

Gitare420 commented 2 years ago

use the same model 071405 finger to read and write, with the id 1

@Gitare420 in the "write_to_sensor" example you have to comment out or delete the line "memset(fingerTemplate, 0xff, 512);" if you've manually put the template data in the array buffer before this line. (as you have done). This line was simply done to initiate the array buffer when it was previously empty. So comment out his line and let me know if it works or not. IMG_20220906_185054.jpg

Gitare420 commented 2 years ago

I made the change and left everything as it is and it still doesn't work, it reads the template and uploads it without problems, but when reading the fingerprint it can't find it in the database.

It occurs to me perhaps to filter the data that is not necessary and save the template in a string, and when reading it see the percentage of coincidence, and if it is greater than 80%, for example, I would take it as good. I'm going to sleep for a while and when I wake up I'll do that test and let you know how it goes, thanks for answering :)

hanifizzudinrahman commented 2 years ago

I was also in need of such functionalities (to read, save and write back template data to similar sensor models) and thus came up with an update to the existing library. @Dygear what you said is correct. I have a pull request pending about this. Please checkout my repository about this update. Also checkout the changes I've made.

However, keep in mind that writing template data from one model to another won't serve the purpose as different sensor models might use different template matching algorithms.

Hope I was able to help!

yap, that's right

AsifKhan991 commented 2 years ago

@Gitare420 @hanifizzudinrahman I made some changes in the write_template_to_sensor() function. Check if it works now. Also currently I don't have access to the modules. Tomorrow I will have them and check again thoroughly.

Hello, I updated the library and it's still the same, from what I've seen my model 071405 is the least used, it may be the reason why it doesn't work, these are the data that the fingerprint example gives me:

Reading sensor parameters Status: 0x0 SysID: 0x0 Capacity: 300 Security level: 3 Device address: FFFFFFFF Packet length: 128 Baud rate: 57600 Waiting for valid finger... Sensor contains 1 templates

I think I'll buy the 307 model through AliExpress (it doesn't exist in Chile) and I'll keep trying there so as not to waste my time, I'll be attentive to the updates, thank you very much :)

There were indeed some issues with template buffer size. Those are now fixed. @Gitare420 sorry to bother, but will you please let me know if the issue is now solved or not? (use the new "get_direct_template.ino" example to get the template)

Hello, sorry for so many doubts, this is the last one hahaha, how can I write the templates from an sd card? I use an esp32 and the libraries:

include "FS.h"

How can I write all that in the function

uint8_t fingerTemplate[512]={0x03,0x0E,....your template data.....};

As I understand memset(fingerTemplate, 0xff, 512); has something to do with it.

Thank you very much in advance :)

dody3030 commented 2 years ago

Hello everybody, I'm confused about the template size, I got R503 fingerprint when I read the datasheet I noticed that the template size is 768 bytes not 512, is there is anything I need to change in AssifKhan991's libraries. Thanks in advance

AsifKhan991 commented 2 years ago

@dody3030 just change the array buffer size to 768. I.e : finger.get_template_buffer(768,your_arr_buff) to get the template data and finger.write_template_to_sensor(768, your_arr_buff) to write template back to sensor.

dody3030 commented 2 years ago

write_template_to_sensor

@AsifKhan991 what about the memset(ref_buf, 0xff, 512) in Adafruit_Fingerprint.cpp

The controller get crash and reboot immediately after successfully store the model finger.storeModel, so the finger is stored successfully, then the model is loaded successfully, getModel(), the crash start after calling the function finger.get_template_buffer ` Serial.print("ID "); Serial.println(id); s = finger.storeModel(id); if (s == FINGERPRINT_OK) { //id = (finger.templateCount + 1); Serial.println("Stored!"); finger.LEDcontrol(FINGERPRINT_LED_FLASHING, 25, FINGERPRINT_LED_BLUE, 20); finger.LEDcontrol(FINGERPRINT_LED_GRADUAL_ON, 200, FINGERPRINT_LED_BLUE); delay(2000); finger.LEDcontrol(FINGERPRINT_LED_GRADUAL_OFF, 200, FINGERPRINT_LED_BLUE); delay(2000); finger.LEDcontrol(FINGERPRINT_LED_GRADUAL_ON, 200, FINGERPRINT_LED_BLUE); delay(2000); finger.LEDcontrol(FINGERPRINT_LED_GRADUAL_OFF, 200, FINGERPRINT_LED_BLUE); delay(2000); } else if (s == FINGERPRINT_PACKETRECIEVEERR) { Serial.println("Communication error"); return s; } else if (s == FINGERPRINT_BADLOCATION) { Serial.println("Could not store in that location"); return s; } else if (s == FINGERPRINT_FLASHERR) { Serial.println("Error writing to flash"); return s; } else { Serial.println("Unknown error"); return s; }

@dody3030 issues with your code:

1) You are using f_buf[512] when you mentioned your template size is 768 bytes. So replace all 512 to 768 in your code

2) Did not call the finger.loadModel(id) before calling finger.getModel(). Refer to "show_saved_template.ino" example.

Actually am trying to get the hex values during the enrollment, so do I need to loadModel() before I getModel?? I checked your previous code examples trying to understand in which stage exactly I have to get the hex, taking into account the template size is different, I will use your example get_direct_template. thank you for your replies really appreciated.

Usually the template remains on the char buffer if no other operation's done after enrollment. But it might be otherwise due to model variation. So yeah, safe to do so.
