Hi, before I purchase, does XIAO ESP32C3 work with PN5180?
Where can I get the information to help me set it up? If so,
Thank you
Hi there,
So I’m Curious have you read the Data_sheet? if so you would see this:
One host interface based on SPI is implemented:
• SPI interface with data rates up to 7 Mbit/s with MOSI, MISO, NSS and SCK signals
• Interrupt request line to inform host controller on events
• EEPROM configurable pull-up resistor on SPI MISO line
• Busy line to indicate to host availability of data for reading
This matches up Nicely IMO, Do you have some code to post , Using the code tags above “</>” Paste it in there. We can look.
It is a very capable NFC reader. Paired with a Xiao would be a Great integration of tech.
