PN532 NFC/RFID module with STM32F103

Hi all.

I have a project that need to connect a NFC reader/writter to STM32F103. The MCU module is designed myself so I will not mention about some modules like Arduino,...As far as I know, PN532 is a good choice for my project.But I have some doubts, please clarify me.1. For some PN532 module like PN532 NFC/RFID module of elechouse,... What is the best choice for connection between NFC module and STM32F103? I am considering between HSU(High Speed Uart), SPI, I2C.2. I don't see any PN532 NFC/RFID libraries for STM32F103. I mean that libraries is commands that STM32F103 use to control PN532 module operation. Does anyone have this labraries? If yes, how can I use this libraries for my project?

I'm in the initial stages of project, don't know what i should do, and what is the best path. So Please help me.

Thank you so much. #debugging

Research the hardware more thoroughly and experiment. Look for C libraries for other platforms, and integrate the USART IO level with ST firmware libraries.

Hello, I have the same problem. I use SPI communication, but the PN532 does not respond with correct bytes. Did you succeed with UART?

It seems improbable that he's that far along..

''What is the best (sic) choice for...''

There is no such thing as ''best'' - without a set of criteria with which to judge it!It's your  project, so you  need to think about your  specific requirements & constraints and what most closely fits with them.''I don't see any PN532 NFC/RFID libraries for STM32F103''Think about it: the PN532 doesn't operate differently when connected to an STM32 from when connected to anything else - does it?So don't expect there to be a specific, unique ''STM32'' library - rather, as clive1 suggests, look for a general  library and think about how the STM32-specific bits can be adjusted...This is the basic way to approach any  project...

''the PN532 does not respond with correct bytes''

So what bytes does  it respond with?What thinking/testing/debugging have you  done to determine why this might be?
