Unable to run templates example in R551 #16

Closed MaazSk closed 5 years ago

MaazSk commented 5 years ago

Hie, I tried running the templates example but was not able to successfully run it I am getting the following message please help me resolve it. I have changed the buffer size to 496

TEMPLATES test

Below is the text which I am getting after I have removed the debug comment

Thanks and Regards Maaz Shaikh.

brianrho commented 5 years ago

Why did you change it to 496? Does it work with the default 768 bytes buffer?

brianrho commented 5 years ago

Run the example as it is, change ONLY the pins and disable debug

MaazSk commented 5 years ago

I am getting the same error. Running the example code provided in the library

It is not working with with the default 768 neither it is working with 496

brianrho commented 5 years ago

Edit the sketch and add a Serial.println(count) after it prints the error message you're getting. Run it with 768 bytes as usual and let me see

brianrho commented 5 years ago

Have you tried it? What did you get?

MaazSk commented 5 years ago

Hi briarho, I'll try it tomorrow as I don't have the access to my laptop and fingerprint sensor today I'll just check it by tomorrow and will let you Thanks and regards

Where did you place the print?

MaazSk commented 5 years ago

Below is the code where I have place the print command

while (true) {
        bool ret = finger.readRaw(FPM_OUTPUT_TO_BUFFER, buffer + pos, &read_finished, &readlen);
        if (ret) {

            count++;

            Serial.println(count);   //// Here I am printing

            pos += readlen;

            readlen = buff_sz - pos;

            if (read_finished)

                break;
        }
        else {

            Serial.println("Error receiving packet");

            return 0;
        }
        yield();
brianrho commented 5 years ago

Change this IF statement at line 305 at FPM.cpp:

   if (len != chunk_sz) {
        FPM_DEBUG_PRINT("Read data failed: ");
        FPM_DEBUG_PRINTLN(len);
        return false;
    }

to:

   if (len != chunk_sz) {
        FPM_DEBUG_PRINT("Read data failed: ");
        FPM_DEBUG_PRINTLN(len);
        Serial.print("Len: "); Serial.println(len);
        return false;
    }

and try again.

MaazSk commented 5 years ago

I have done the suggested changes but still I am not able to get the desired output. Below is the message which I receive on the Serial Monitor.

brianrho commented 5 years ago

The changes are to find out what's going on, not to fix it. What are the current baud rates for Serial and SoftwareSerial? What is the buffer size? And, did this example ever work before with this sensor?

MaazSk commented 5 years ago

The baud rate is 9600 for serial and 57600 for software serial buffer size is 768 and tried with 496 also. No, this example did not worked with this sensor

brianrho commented 5 years ago

Stick with the 768 byte buffer for now, don't want it running out of space. Which buffer size gave the results you sent earlier?

MaazSk commented 5 years ago

Okay I will stick to 768 only. Can you please a tell me about which results you are talking about.

brianrho commented 5 years ago

Just rerun the most recent changes I sent you and post the results

MaazSk commented 5 years ago

Okay

Okay, comment out that whole IF block and run the sketch again. Paste everything you get especially the size of the templates printed at the end. Find out if its consistent across different finger IDs.

MaazSk commented 5 years ago

Okay wait

MaazSk commented 5 years ago

This is what I am getting the length is constant

No I said you should comment out the whole IF block that contains that statement. In FPM.cpp

Ohh okay

Okay, seems so. When it asked for a new ID, what did you enter? Try entering an ID you've never used like 200 or something

MaazSk commented 5 years ago

okay

MaazSk commented 5 years ago

I am getting the same message

brianrho commented 5 years ago

Are you sure your sensor is an R551? Not only is the template size different from the 768 expected, but it also seems it doesn't support the DOWNCHAR command which is necessary to upload templates. Do you still have the product link?

MaazSk commented 5 years ago

I don't have the product link right now but I am sure it is R551, and yes the template size is different than other sensor and to that which is mentioned in the datasheet I'll just dig in and find the product link and will provide you till tomorrow Thank You!

brianrho commented 5 years ago

Sure. You can try a few things later like:

MaazSk commented 5 years ago

Okay I will try and let you know

MaazSk commented 5 years ago

If I increase the buffer size then the arduino is not working because I have only 1024 bytes on the arduino uno and I have changed it to 0x01, 0x02, there is no change in the output

brianrho commented 5 years ago

No the Uno has 2k bytes for RAM. How many bytes does it report are left after compilation?

Also did you try 0x03 like I said?

MaazSk commented 5 years ago

Yes I tried 0x03 also as u said. Let me check the bytes and will let you know

No the Uno has 2k bytes for RAM. How many bytes does it report are left after compilation?

Also did you try 0x03 like I said?

Uno has only 1 Kb of RAM

Yes I tried 0x03 also as u said. Let me check the bytes and will let you know

The Uno has 2k of SRAM: https://www.arduino.cc/en/tutorial/memory

Place this in the sketch immediately after it prints the Unknown Error in move_template():

Serial.println(p);

I want to know the returned error code.

MaazSk commented 5 years ago

This is what I get

Unknown Error -2

brianrho commented 5 years ago

Make sure buffer[1] = 0x01 always in uploadModel() in FPM.cpp. Then inside the function, place Serial.prinltln(rc) right inside the first IF block, before the function returns.

Okay, in read_ack_get_response() in FPM.cpp, replace this:

    /* wrong pkt id */
    if (pktid != FPM_ACKPACKET)
         return FPM_READ_ERROR;

with:

/* wrong pkt id */
    if (pktid != FPM_ACKPACKET) {
        Serial.print("PID: "); Serial.println(pktid);
        return FPM_READ_ERROR;
    }

PID: 1 -2 Unknown Error -2 This is the output

brianrho commented 5 years ago

Well, that makes no sense at all. I'm afraid I can't do much more than this without having the sensor myself. And it seems theres isnt a lot more to be done anyways, nor is it worth it, given the disparities between the sensor's actual behaviour and whats described in its "datasheet". You'll have to either leave this functionality or get another module like the FPM10 or R307. I'll add another warning about this module to the readme, a good chunk of the messages here are a result of modules claiming to be the R551.

MaazSk commented 5 years ago

Okay, Thank you bro. Can you just explain me how the templates are moved from one ID to another, I will carry on the research and if I find something that is helpful I will post here for sure so that you can make the necessary changes. Once again thanks a lot.

brianrho commented 5 years ago

The code is mostly clear I think. After you've downloaded the template to your array, just follow the steps in move_template().

The DOWNCHAR command is first sent to the module to initiate the transfer of the template to the module. As part of the command, you supply the particular buffer 1 or 2, that is the temporary destination. The device must ACK the command (which is what has failed so far) before you can begin the actual transfer of the template with writeRaw(). After which you then store the template with the STORE command, passing in the new ID. The module internally transfers template from the internal buffer to the specified ID.

Okay Thank You!
