I would like to pilot ST25R3911DISCO with labview (8.6). I have imported ST25R3911DISCOComm.DLL to LabView and I use GetST25R3911 from the DLL to get the handle and to redirect it to checkConnection for example. The problem is i do not know the data ...
Hi all! I've got a strange problem during writing data to a tag and inventory (sometimes). I have the Preamble error (-35). This is the result of gen2WriteWordToTag function or st25ru3993TxRxGen2Bytes function during inventory. Idesigned my own hardw...
