The project consists in using an "Elechouse PN532 NFC module V3" to read Mifare cards, Mobile phones with NFC, aswell as modern credit cards with NFC. From these, it will be read any id that may be used as unique identification, in order to use the credit cards aswell to grant access to a room.
Therefore, I would like to contract a freelancer to provide me with a working code to read all those three mediums (Mifare, NFC mobiles and credit cards) on a PN532 connected to an ESP32 over I2C and over SPI (need both connection types).
1) I need a working sketch for the three types of badges and two type of connections, and that works "out-of-the-box" for an ESP32 and the PN532 indicated in the statement, photo is to be found here: [login to view URL]
2) I have already tried with the standard PN532 libraries and didn't work, so do not send me these again.
3) Please accept this project ONLY if you are able to finish within your given budget.
