• It seems we don't need resistors as long as the OV7670 pins are configured as open-drain by default (we implemented the I2C SCL and SDA as open-drain from the code).
• We need to connect MCLK to 24MHz, we can do that using STM32 PA8 (MCO).

After going through the different OV7670 manuals it seems the pins are not configured as open-drain by default, meaning that we should probably use resistors connecting the Microcontorlar and Camera module pins (specifically, 4.7kΩ)
