R503 led_control problem

hi please help me R503 sensor led_control problem "no matching function for call to 'FPM :: led_control ()' '

Well, you can clearly see the function prototype requires 4 arguments so why are you calling it without any? I don't have any examples at the moment. If you can find an R503 datasheet, I may be able to add an example to the library.

Is this the R503 data sheet that you need ??

R503 fingerprint module user manual.pdf

[brianrho]

Yes, this seems to have some documentation on the command but it's not very clear. I'll look into it and maybe have an example out in a few days. Since I don't have the hardware, you'll have to do all the testing on your end.

[ardiwidiyono]

thank you very much thank you ...
I patiently waited ....
do you have a youtube channel ??

[brianrho]

Nah, I don't have a platform like that.

To be clear, can you still use the sensor, without controlling the LED yourself? Right now, it's controlled automatically when you place your finger, right?

[ardiwidiyono]

if I use fingerprint enrollment, it can be saved, but if I use an example, the fingerprint sensor is not detected ...
when i use enroll LED it doesn't show any response ...

[brianrho]

How do you mean the sensor is not detected? Aren't you using it for enrollment, as you said? Specifically, which exact examples do not work?
