This address must be a 7-bit address number which means that the limit is 127 device addresses.Īrduino has a special library called Wire.h that works with the SAMD11C. In order to have multiple devices, all of the devices must have an address. Multiple devices can be connected to these two lines as long as at the end they have the pull up resistors. These two lines must always have pullup resistors, so that when they are idle, they are HIGH meaning that they are pulled to a 5V voltage. SCL > stands for "serial clock line" which is constantly alternating between high and low voltage, at a constant speed therefore the devices always know when to expect a bit. The devices pull it low to write the bits. SDA > stands for "serial data line" whcich transmits the bytes of your message, one bit at a time between frame bits and with start and stop condition bits. The devices are connected using two wires: Communication can be two way, but both master and slave devices have to have a way of knowing when to transmit. I2C is the same aas IIC which stands for Inter Integrated Circuit, it works with two wires and sends bits one at a time between a master device and a receiver device. The first thing was to learn how the serial I2C bus works.
