STM32: Busy flag is set after I2C initialization

WebI2C can be used to connect up to 127 nodes via a bus that only requires two data wires, known as SDA and SCL. SDA=4 => D2. SCL=5 => D1; SPI. SPI is much simpler than I2C. Master and slave are linked by three data wires, usually called MISO, (Master in, Slave out), MOSI (Master out, Slave in) and M-CLK. M-CLK => D5; WebSCL is a serial clock pin for the I2C interface. SDA is a serial data pin for the I2C interface. VCC provides power to the module. You can connect it to a 3.3 to 5 volt power supply. GND is the ground pin.

SDA is the data line in which the data bits are transmitted and received. I2C is a half duplex communication since there is one data line. SCL is the clock signal line which is used to synchronize the communication. barbara opal obituaryWebThe SCL line is used to transmit the clock signal that synchronizes the transfer of data between the devices on the I2C bus, and the master generates the clock signal. The other line is the SDA line that is used to send the data.
