Description
STSW-ST25RU003 software comprises of the
ST25RU3993 firmware source, which is a
USB/UART bridge over USB controlled
application for STM32L476.
It allows the GUI on the PC to control the
ST25RU3993 on the ST25RU3993-EVAL board
and exchange arbitrary RF frames. The provided
project is ready to be compiled using the Keil
®
toolchain.
