Hello,

1. Please check if the communication between Teensy board and Grove NFC 1.1 is happening properly. Apart from UART, Grove NFC supports I2C interface (See Wiki )

2.The distance between Tag and NFC antenna must be very minimal (few mm).

Re: BBG ADC I2C Grove Problems

Hello,

Please use the schematic to know how VCC and GND are connected to ADC Input Grove. VCC and GND are already internally connected to I2C Grove connector (i.e. Vcc= 3.3V & GND = 0V).

To measure external Analog signal, use SIG and GND pins. These should be enough.

Thanks and Warm Regards.

Re: BBG ADC I2C Grove Problems

Hello, The issue seems to be that address 0x55 is unavailable and used internally by BBG. This can be seen from UU displayed corresponding to unavilable addresses after i2cdetect -y -r 1 command. Please use the ADC I2C wiki page to learn how to change the default address to 0x50 (i.e make the ADR0 a...
