What is the difference between i2c and spi?
Major Difference Between SPI and I2C is: SPI is full Duplex (SPI can be full/half duplex, depending on the hardware, 3 or 4 wire) and I2C is half duplex communication....we cannt send and receive data at a time in I2c..but it possible in SPI ....SPI much faster Than I2C....... Main topic to discuss the difference is 1) speed is difference in case of i2c is 100/400kbps in 7 bit mode max 400kbps (But High speed I2C communication protocols allow speeds upto 3.4Mbps!!) in case of spi speed is upto 1mbps (the higher speed of SPI is due to fact that unlike I2C, SPI interfaces to a slave device using a sperate pin called the slave select + no concept of acknowledgements which means increased Band width..) 2)Connection wise: i2c require less pin then spi (SPI 3wire: 3 IOs, SPI 4 wire: 4 IOs, I2C: 2 IOs) as spi require slave select for individual device... 3)it is better to use i2c in case of if u want to connect more device to connect. (slave addressing advantageous over SPI slave select individual pins for individual slaves) 4)bus arbitration is possible in case of i2c... not in case of spi... (SPI does not require it, since only 1 slave is controlled by the master at any given point) 6)noise sensitivity of i2c is high... there is chance to corrupt the r/w bit... then whole data is corrputed... but in case of spi.. chance is very less as whole word is trasmitted... However, I must say that I2C is more reliable, since the protocol supports slave feedback machanism (ACK) to detect whether was received correctly or corrupt. 8) it is easy to implement the spi...while i2c is little bit complex...

What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
What is the equation for calculating the phase difference between two waves?
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
What is the formula for calculating the phase difference between two waves?
The formula for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
What is the difference between 164 and 220?
The difference between 164 and 220 is 56.
What is the difference between the CPI and the GNP?
The CPI measures changes in prices over time while the GDP measures changes in production.
How can one determine inflation using the Consumer Price Index (CPI)?
To determine inflation using the Consumer Price Index (CPI), one can compare the current CPI to the CPI from a previous period. If the current CPI is higher than the previous CPI, it indicates inflation. The percentage difference between the two CPI values can be used to calculate the inflation rate.
How can one determine the inflation rate by utilizing the Consumer Price Index (CPI)?
To determine the inflation rate using the Consumer Price Index (CPI), you can compare the current CPI to the CPI from a previous period. The percentage difference between the two values represents the inflation rate.
How can one determine the rate of inflation using the Consumer Price Index (CPI)?
To determine the rate of inflation using the Consumer Price Index (CPI), you can compare the current CPI to the CPI from a previous period. The percentage difference between the two values indicates the rate of inflation.
What is the difference between cpi and cgpa?
The difference is that a CGPA is a Cumulative Grade Point Average. A CPI is a Consumer Price Index. One is a grading system, and one is a financial concept.
What is the relationship between CPI and inflation?
CPI is the indicator of inflation in any country.If CPI is high it means inflation is high.
What is earned value?
EVM is a technique to monitor/track projects. EVM has 2 important index statistics: CPI and SPI. CPI is the cost performance index, and if it's >= 1 it means that the project is OK with the budget, if it's < 1, it means that the project is over-budget. SPI is the schedule performance index, and if it's >=1 it means that the project is on schedule or ahead of schedule, if it < 1, it means that the project is behind schedule.
Is there a difference between a Network hub and a router?
A network hub absconds with any stateful packet inspection (SPI), so it won't act as a firewall.
How can one determine the inflation rate using the Consumer Price Index (CPI)?
To determine the inflation rate using the Consumer Price Index (CPI), you can compare the current CPI to the CPI from a previous period. The inflation rate is calculated by subtracting the previous CPI from the current CPI, dividing that difference by the previous CPI, and then multiplying by 100 to get a percentage. This percentage represents the inflation rate.
What is the differenc between CPI and headline rate of inflation?
In the, CPI is the measure of inflation but elsewhere it may be the RPIX...RPIX includes mortgage payments. So if a country uses RPIX to measure inflation the difference is that the RPIX includes mortgage costs.
What is the difference between cpi and tbi as in 1995 Chevy?
The CPI injection fuel system has a fuel injector for every cylinder. A TBI has only 2 injectors that set's above the center of the intake that's feeds all the cylinders like a carb.
How can one find the inflation rate between two years?
To find the inflation rate between two years, you can use the formula: Inflation Rate ((CPI Year 2 - CPI Year 1) / CPI Year 1) x 100. CPI stands for Consumer Price Index, which measures the average change in prices over time. Subtract the CPI of the earlier year from the CPI of the later year, divide by the CPI of the earlier year, and multiply by 100 to get the inflation rate as a percentage.
