Posted on July 01, 2013 at 12:10Hej! I just bought a DEMO-CR95HF board to sort out EMI problems that I have with my own design with the CR95HF chip. To my disappointment the DEMO board generates more harmonics than my own design. My measurements can...
Posted on July 09, 2014 at 20:43I want to work with the RF transceiver Demonstration Board code and I have found it at this link:http://www.st.com/web/en/catalog/tools/PF257512 However, as far as I can tell, there is only a version of the project bu...
Posted on July 02, 2014 at 16:29Hello I want to build a reader to communicate with ISO14443A and ISO15693 tags using the CR95HF transceiver IC. I build a 2 turn PCB antenna and calculated the matching of the PCB antenna according to AN4327 and the ...
Posted on June 19, 2014 at 15:01Hi,I have two applications one for the Calibration of CR95HF and one for Tag detection. Before running the Tag detection application Calibration is done and the DAC ref value obtained is saved in a file. The Tag detec...
Posted on April 08, 2014 at 15:49Hello everybody, I have my M24SR working with my MCU :) I can read the contents of the tag. However, after a read from MCU, I cannot write the tag if I do not remove power from it. I have performed the DESELECT comma...
Posted on May 30, 2014 at 15:33Hi Guys,We are trying to build a multi-disapline access control reader terminal. The CR95HF was chosen for the design. The reader is not an OEM reader and is required to read a number of cards from Various Suppliers.We...
Posted on June 05, 2014 at 15:44Hi, firstly i am sorry my poor english.I bought a m24lr-discovery kit. In ''stand-by mode'', I made a few measurements at M24LR-Receiver antenna ( M24LR04-E [AC0 and AC1] ). But there is a remaining below ''zero'' sin...
Posted on May 26, 2014 at 23:23What is the recommended way to mange simultaneous I�C and RF data transfers with M24SR IC and 2 Host MCU & NFC Phone?I have implemented mechanism with time Slice , so that each Host has time window to communicate with ...
Posted on June 02, 2014 at 15:00Hello, in my last project I changed the eeprom to the M24LR64E. Now I want to creat an expansion device with an reader Ic. Which ic is the best/easyest for the data connection of the two devices.thank you and greeting...
Posted on May 05, 2014 at 15:37Hello, I am using your stsw-m24sr001 firmware with a M24SR (from the M24SR matrix antenna) and a STM32F4-discovery with a STm32F407VG. I have many problems to use the functions of lib_ M24SR.c. When I use the M24SR_Ini...
