Hi,We are using the ST25R3916 on a custom board.I'm trying to get the wake up mode working using amplitude measurement.AN5320 shows the sequence to get this working.I can measure the amplitude and everything seems to work, but when I enable the wake ...

Hi,Recently we developed a on the fly Firmware update system using the L4 series MCU's.There it worked by setting the BFB2 bit and reading the FB_MODE bit to determine which bank was booted and where the code needed to be erased and written.Now we ar...

Hi, I'm implementing an OTA system using the L486VG MCU.This one has the dual bank option and the BFB2 option bit to enable to boot in Bank2.It works and I can constantly swap the banks and erase and read them.Only when the BFB2 bit is set and there ...

Hi, We are testing the ST25R3916 to read Mifare 1K classic UID's.We manage to initialize the chip and to send an REQA command (We get 00 04 back from the card so communication works!).But we need to know the UID. To do this I found the APDU command:C...

Hi,Before I try this out is it possible to use this library to Decrypt AES-GCM 256 on a WB series mcu?

Got it working, for some reason the D3 interrupt needs to be read twice to clear the interrupt line. First time it's oscillator value in main interrupt (1A) register, second time direct command interrupt in Timer and NFC interrupt register (1B).When ...

Hi Ulysses, Thanks that clears it up! Both mask registers (16 and 18) are of value 00 so all interrupt should work.Still not getting any interrupts when doing the last step:set register 02 to value 0x04 -> osc of and Wakup on.Marvin

Hi Ulysses, Great idea! From the datasheet it seems that 1C is a read only register probably to check which interrupt got fired?Something I don't really get it that the application note speaks of enabling the M_wam mask in reg 18h. Does that not mean...

Thanks for the info!For others searching for more info on this you can read the FB_MODE bit like this:if(SYSCFG->MEMRMP & 0x00000100) { //bank2 is mapped } else { //bank1 is mapped }

Thank you so much 0x93 0x20 works perfect!!!

I2C Sequence to get tag detection working using amplitude measurement

On the fly firmware update on L5 using the dual-bank mechanism

How to know which bank got booted when working with BFB2 bit in STM32L4 MCU's

APDU for UID (MIFARE 1K CLASSIC) no response

Can I use CubeExpansion_Crypto_V3.1.0 with the STM32WB series?
