The most comon OV7670 Cameras I found in tutorials have SIOC SIOD instead of SCL SDA, HREF instead of HS and XCLK instead of MCLK. WebThe 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. There is no constant connection between master and slave, transmitting and receiving on the bus. Web11 Oct 2024 · Actually the cause of SDA being low is the I2C Slave, which was in mid-transmission before the MCU was reset. However now the Slave isn't receiving SCL pulses from the I2C Master and so it cannot complete its transmission. Most I2C Slaves don't timeout and release SDA in that situation, although a few do. get started with mongodb
