Hi, i am working on a mobile android application, and from the firmware team they told me i need to this procedure:1. User closes his mobile phone to climatic sensor.2. A mobile app send a ManageGPO command (0x80) to ST25DV64K chip.3. This command ra...
My goal is to send an interrupt signal to MCU, and this couldn't be done via mST25DVTag.manageGpoCommand(ST25DVTag.GpoCommand.INTERRUPT), and it jumps to the catch part.I am a beginner to the field and would really appreciate your help!
I want to interface the ST25RU3993-HPEV with Bluetooth. Would like to replicate the existing USART(USART2) to USART3. After disabling the LED driving sessions and configuring it for USART, its not working as intended. Request to share the changes nee...
Hi What and all will be the effect of changing the baudrate from 3000000 to 115200?? Is there any reference available on this topic?Suggestions appreciated.
I have an ST25R3916-DISCO board which I am using to communicate with ST25 tags with an antenna. I'm using the ST25R3916 Discovery GUI to see the tag information on the computer. My antenna is being recognized, but how do I read the RSSI value of the ...
Hello, Till now I was using ST25R3911B NFC chip for read/write (ISO15693).Unfortunately ship have long lead time. Can you please advice me which chip to use as alternative to have less changes on the PCB as possible?? (ST25R3912, ST25R3915, ST25R3917...
Hi, Im searching for develop a NFC reader using the CR95HF IC transceiver, but i dont know if ST has a STM32 MCU firmware bridge to be programmed. The CR95HF should be connect to PC and the commands sent through the 95HF IC.I want to connect the CR95...
Hey, I recently ordered an ST25R3916-DISCO board for communicating with ST25 RFID tag antennas. I connected the board to my PC via the micro-USB cable and was able to detect my antenna via the R/W feature on the MCU. Furthermore, I downloaded the ST2...
What is the default value of user memory and where is this stated in the datasheet for the ST25DV NFC EEPROM chip?
Good morning,I'm designing a board based on ST25RU3993-HPEV development board. I'm finding some problems in understanding which oscillator to use. On both schematic and dm00717148 is said that only one oscillator between XO and TCXO should be used bu...
