Hi, we're using the MB1054A board for reading ISO 15693 tags and it works OK.

the problem occurs after immediate power down- we are facing problems with initiation.The OS on the PC is Win-10 and we're not sure the CR95HF.dll is the same used on the application SW. how come when shut down the PC and power up again, and then open again the application SW everything is working OK?Do ST supply source code example for the PC side?

Hi,

I need more details to be able to reproduce the issue : I understand that the initiation doesn't work after power down. What do you mean about Initiation ? is it MB1054A power down, software power down or computer power down ? About source code example : you can read Application Note AN3954 that explain how to develop software to drive M1054A board : http://www.st.com/content/ccc/resource/technical/document/application_note/50/3e/09/39/51/a5/4c/3d/DM00034558.pdf/files/DM00034558.pdf/jcr:content/translations/en.DM00034558.pdf Also available, source code examples (C & VB6) :  http://www.st.com/content/st_com/en/products/embedded-software/st25-nfc-rfid-software/stsw-95hf002.html Best regards ST support

Hi,

The power down reffers to computer sudden shut down.After power up of the computer we have problems with proper readings of the tags.We think it's CR95HF.dll problem and the examples of the source codes are not sufficient.How come when using one of the eval SW, after PC shut down and power up, and then re-open the SW- the data of the tag is being read OK?We must understand this issue because other solution is to use other board with proper SDK.
