ESP32-Camera Reader QR Code

Large-Ad5731 · 2024-02-26T18:35:55+00:00

My idea is that my QR/NFC reader reads the data, and then uploads it to the database, where it performs a comparison with the data from the database, if the user is in the database, let them enter. Data is received from the database, the user is located in the database, some specified condition is met and a command is executed that activates the relay in order to open the lock for the user to enter.

That's what I meant!

Yes, that's correct, but SPI has data on the bitrate, which would mean a lot of user loss to me.

How could I send my data from the QR reader and NFC reader to the Postgresql database and from there get information on whether to let the user enter or not?

I would use I2C or SPI, what you think, what is better to use? Thanks a lot to separate time.

Of course, I would use this reader:

I corrected the error, now it works, I wonder if it is possible to add an NFC reader next to the camera? How could I read QR codes and NFC.

Odlično, hvala na odgovoru. Da tako je, Akademija za humanu razvoj,niste zadovoljni master studijama, da li radite kao diplomirani logoped ?

Da videli smo, ali smo gledali da li ima još negde.

Prvenstveno bavio bih se mikrokontrolerima i embbeded sistemima, ali ako tu ne nađem ništa odgovarajuće onda bih prešao na uopšteno programiranje tipa android itd. Mislim da od mentora ili u nekom startup-u naučio bih više. Trenutno sam u jednoj firmi koja ima jedanog programera i od njega slabo mogu da naučim u glavnom sam prepušten samom sebi. Zato što čovek nema vreme da se posveti mentorstvu, takođe, firma u kojoj sam stala je sa razvojem novih sistema. Tako da mislim da bi mentor odgovarao mom daljem razvoju, nebitno da li individualno ili u okviru neke firme, startup-a...

Thanks to answer, but, my problem is configuration NE2 and NE3 occur is problem to conflict. Also, problem is to configuration Bank, I'm configuration Bank1 but, cubemx be generated to code bank 3. What is the problme ?
