Hi,I'm working with a ST25R3911B RFID chip associated to a STM32L072 uC.I use the "STM32CubeExpansion_NFC5_V1.2.0" project, ported from STM32F401 to STM32L072.This project enables to set the ST25R3911B in wake-up low power mode.Now I'm trying to set...

Hi Grégoire,I think the best way is to share the code with you.Is it possible to do this in a private mode ?Now I have removed the maximum useless functions I have created to direct acces to ST25R3911B registers.I no longer call the IRQ functions too...

Hi Grégoire,it seems that the rfalWakeUpModeHasWoke() always respond me 0.I guess it means the RFAL_WUM_STATE_NOT_INIT.I don't know how to correctly set the rfal states ?Is a documentation available for the rfal driver ?Best Regards,Matthieu

Hi Gregoire,Ok so during wake-up from STANDBY mode if I call rfalWakeUpModeHasWoke() after checking PWR_FLAG_WU (for wakeping the STM32) it respond me 0.Anyway it works I can read a RFID badge and the STM32 is correctly initialized.Then after having ...

Hi Ulysses,the architecture I'm trying to do is the following :STANDBY mode -> Wake-up with RFID -> Do Radio things -> STOP mode or Low Power Run Mode This is simplified but the idea is really to save power in order to have the best autonomy .That's ...

Hi Ulysses,indeed no OS is used for our project.The idea is to be careful to the consumption because it is powered with battery.So I use STANDBY mode, STOP mode will be used after wake-up of the STM32.I don't know if the HAL_GPIO_ReadPin function can...
