Hello we have integrated ST NFC RFAL stack with RL78 IC and currently we are able to detect NFC card within 1-2seconds. Is there a way to reduce this time less than 1 second to detect NFC card ?
Hi,
if those two didn't heavily improve, then: analyze the timing behavior, in a first step use a logic analyzer on SPI + IRQ and find where time is lost, could be SPI speed, CS setup and hold times, incorrect timers in platform, ......
If unsure after a first analysis to ensure correct SPI decoding and looking at timings you can also post a trace here.
BTW: How are you measuring this time to read a card? What are your start and stop signals for this measurement?
