Resolved! Porting of RFAL Library to STM32F051

HiI am using the ​NFC5 V1.3.0 for the STM32L053R8-Nucleo as an example to port the RFAL library for using with either a STM32F051 or STM32G071. I replaced the Systick/NVIC/EXTI/GPIO/SPI Hal and everything seems to work, except that when I want to rea...

Resolved! Can we address multiple ST25DV from a single master on the same I2C bus independently ?

The idea is to stack 3 X-NUCLEO-NFC04A1 on top of a NUCLEO-L476RG and access one X-NUCLEO-NFC04A1 at a time either from RF or through I2C using the X-CUBE-NFC4 or directly through HAL APIs.We were thinking of disable RF of two X-NUCLEO-NFC04A1 and en...
