I2c

I2C is a two-wire serial bus

Spi

Serial Peripheral Interface (SPI) is a serial, synchronous bus commonly used in embedded systems

Post faster

Quality Example
Faster

"I wanted to know that what makes spi faster than i2c"

from question "What makes SPI faster than I2C protocol"

"Post explaining why spi is faster than i2c"

from question "When I should use I2C and when I should use SPI?"

Research last control

Quality Example
Faster

"I have done some research about them and it seems to be that spi is faster than i2c but the last one ensures more control and error detection over the first one"

from question "* (no title is found for this review)"

Bus slower

"On top of that the i2c bus is slower than spi because there are control data exchanged"

from question "Processing Sketch Using Data from Arduino is Lagging"

Others

Quality Example
Better

"How is spi better than i2c at these temperatures"

from question "Effect on I2C Communication with change in Temperature (Extreme Temperatures)"

More complex

"Communication via i2c is more complex that with uart or spi solution"

from question "Multiple i2c can't work with arduino uno"

"I know i2c is more complex slow than spi uart etc. but it s a constrain"

from question "* (no title is found for this review)"

Way more

"First bit banging i2c is way more complicated than bit banging spi"

from question "I2c bit banging Programming using C"

Not less

"Spi is not less limited than i2c in this case"

from question "Effect on I2C Communication with change in Temperature (Extreme Temperatures)"
