Serial i2c bus - nfc function

WebThe I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) where the Arduino writer board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices. WebThe image is a slight generalization, for drivers using I2C or SPI, they must run in the background thread so that the highrate communication with the sensor does not affect the main loop’s performance but for driver’s using a serial (aka UART) interface, it is safe to run in the main thread because the underlying serial driver itself collects data in the …
