STM32F103 can realize qr code identification function? Did I have qr code modules, but the program source code, want to ask STM32F103 can realize this function

CodePudding user response:

Qr code modules have TTL232 and USB interface, can communicate through STM32 UART and module (internal usually have level conversion module 5 V to 3.3 V), has dealt with qr code identification module, MCU receives the data processing should be ok, program can go to taobao, or you can take to find this kind of module,

CodePudding user response:

External image sensor from image processing is not enough

CodePudding user response:

Seeing you is want to do
If just like say "use" on the second floor, that you directly use ah, interface module will surely leave you out
If you want to make a, you look have a ready-made online library

CodePudding user response:

With open source libraries, some do development board of the tutorial is routine

CodePudding user response:

Have see manual stm103 module module will be all right
