im using pn512 with cortex-M3 mcu and going to pass the EMVCo contactless EMVL1,,software version is NXPNFCRDLIB v4.040.05.011646_20161115,but i got a issue with EMD error handing, i think the reason is pn512 too slow to reveive new data after ignore this EMD error,does it can handing the EMD error ASAP?
which ic can replace it if it cant pass emvco? better have the same pin sequence,thank you.
We've passed the EMVCo. by using PN512 few years before. I thought the IC is OK. Would you explain more detail about your issue that there are many persons here could show you their recommendation.
we also have passed the emvco 2.4 few years before,but emvco have added some new cases after version 2.5 which about EMD error hanlding(case TA335 TA430).
PCD PN512 PICC
the interval time between noise and ATS just 1280fc,its about 94us,its too short to handle the noise.
