In BBBWL - SPI port used is ... I'm trying to connect m24sr to stm32f407vgt. I switch to I2C2, clocking from an external resonator at 8 MHz, SYSCLK 72 MHz, I use a converted library for Open107V. For stm32f107vc this code worked, but when switching ... I'm Using the CR95HH under a linux Microcontroler. in this case, I'm using the UART port to communicate (not SPI), the default BaudRate is 57600, and works fine, but when I try to change the Baud rate to maxim... Hi all I am making RF reader using ST25R3911B. Communication distance should be more than 50cm. Please let me know if is possible without an external power amp. Regarding the reader HF ST25R3911B nucleo board X-NUCLEO-NFC05A1: is possible to have also the stack-up and the infos on built materials in order to have the right impedances ? Thanks a lot Hello, we made custom reader board with CR95HF. This reader is interfaces with IMX6 CPU running linux. Communication with reader via SPI bus. I tried to read DOC9303 biometric passport. I can read it on default speed... Hi, I'm building an UHF RFID reader using ST25RU3993 and I have a problem reading the registers. The idea is to connect the IC to NodeMCU or Arduino (both are programmed using Arduino IDE at this stage). I c... Hi all, I am looking at the ST25R3911B-DISCO board and I want to see what the inductance is of the coil they have on the eval kit. I can't seem to find the formulas for this specific application where you have 2 coils... Hello In lib_iso15693pcd.c : function ISO15693_WriteSingleBlock. It seems that the return value of PCD_SendRecv is not handled. The function ISO15693_WriteSingleBlock returns alwa... As we know,RFID has a big market.But we only use R2000 by Impinj to develop new reader.The R2000 is not open source system.So we need a new chip to instead of it. So when do we use the demo of ST25RU3993 or other UHF ... Hi, i am using CR95H RFID CLICK module with raspberry pi3.I am using UART for communication. I connected, SSI_1 => GND SSI_0 =>... Hi All, I want to get detailed STS3921 datasheet(including pinmap, pacakge and other electronic specification) and reference design. on ST website, I can only find a brief introduction as below link. Would you please... Hi Folks, I´ve got a task for which i have to implement a NFC Reader(CR95HF) into a casing, so I decided to order the above mentioned board to help me get into it. Now I´m searching for a suitable... I've bought one X-NUCLEO-NFC05A1 board, all ST25R3911B_Discovery_GUI functions work fine. But i cannot find the mifare classic function on the GUI. Is there any update for this? Where can i fin... Hi, I am working on a project within which I am using HF RFID reader. More particularly #ST25R3911B 1.4W NFC reader. I was searching for the right code for reading tags with this but didn't have any luck.... Hello, I am working with CR95HF IC. I have some questions regarding it. 1. How much read range can be achieved with how much Henry of antenna inductance. Can any one Please suggest.? 2. Is it required that Antenna ... Hi I have the following problem with above mentioned function: Every time i command the CR95HF to get in the Tag Detection Mode it wakes up immediately. I get the following response from CR95HF: 00 01 02 The C... My Samsung mobile upgraded from Android 6.0 to 7.0. But after that the 24SR seems can't detect from mobile NFC. It happens only after the 24SR IC locked in read/write. For unlocked the chip by 24SR discovery bo... Using the ST25R3911B, I am making RFID reader. I want to make the communication distance more than 50cm. Please let me know.
