@Hootie81, there IS a difference between using <> and " " for #includes and it has to do with where the compiler searches for the file. Here is the "official" definition:
Quoted form : This form instructs the preprocessor to look for include files in the same directory of the file that contains the #include statement, and then in the directories of any files that include (#include) that file. The preprocessor then searches along the path specified by the /I compiler option, then along paths specified by the INCLUDE environment variable.
Angle-bracket form : This form instructs the preprocessor to search for include files first along the path specified by the /I compiler option, then, when compiling from the command line, along the path specified by the INCLUDE environment variable
So to search for a file in the "current" directory along with the compiler specified path, you need to use quotes.
Well that makes perfect sense for the way I was doing it then now I need to try and get all the hardware working togetherā¦ I remember reading about spi speeds changing between the digole and the SD card sounded like a reasonably easy fix to make if it hasnāt been corrected already.
I did have a little issue with the print reader todayā¦ When doing the serial pass thru and enrolling prints consecutively it came up with a strange error and couldnāt enroll the prints so I clicked the capture image button and the picture was half of one print and half of another. I tried flashing different firmware to see how it works. Just the normal reader example, without power cycling the fingerprint reader. It didnāt throw any errors but it couldnāt find any prints. Cycling the power off and on fixed it first go
@Hootie81, we have not found a solid fix for the Digole/SD SPI mode change yet. You may want to put the Digole on I2C to avoid the problem entirely. Soon, there will also be a second serial port available, making it even easier to hook up.
The serial passthrough is very basic code and Serial1 is not truly hardware implemented so it can drop data occasionally. This is perhaps what happened though the outcome was kinda weird
Hi i am also working on a project using the arduino finger print scanner
I made use of the codes @peekay123 provided, i also tried using one of the examples providedā¦
but i get a compile error please how can i go about this

@Tk_Yussuff, I must have had a brain fart when I prepared that library for the web IDE cause it had a bunch of issues. I now fixed all those and published the library to the IDE so you can use it there. Let me know how it goes!
Yeah i remember just removing a whole bunch of arduino stuff to get it workingā¦ it has been a while since i played with the reader, but was working perfectly, much better than my commercial one installed at my house.
i did start noticing some little glitches that had me stumped but it turned out to be a loose connection in the breadboard!
i used the 3v3* line as you can see in the video above, didnāt notice any issues besides a bad connection in the breadboard would cause the reader to not respond. that was a bad connection though not a power issue
Can some one tell me if i get the template of a fingerprint using showtemplate code and then i want to use it to match my fingerprint with another template.how i should do that.
and what finger.image2tz and finger.creatmodel does?
hello am trying to use my photon and the fingerprint that u having .
am trying to use the code but none of them is compiling .
is this code gunna work just for spark or it can be use for photon also?thanks .
'#include "application.h"
void setup()
{
// Open serial communications and wait for port to open:
Serial.begin(57600);
Serial1.begin(57600);
}
void loop() // run over and over
{
while (Serial1.available())
Serial.write(Serial1.read());
while (Serial.available())
Serial1.write(Serial.read());
}
sorry about that sir u right .
am confused about it .
so do i have to use the TTL serial to communicate ?
i cant use the the photon and the fingerprint the photon has the RX/TX
correct me if am wrong
thanks

@peekay123, can you push a version that incorporates this PR to Build?
