I2C is known as TWI (two wire interface) in Atmel speak I2C is proprietarary to Philips, and the name is trademarked; you have to meet certain licensing conditions to be abe to use the name "I2C" Many people people make compatible devices but, presumably, don't want to jump through Philips' hoops - so they just don't use the name "I2C" They use names like "TWI" or "TWSI" (Two-Wire Serial Interface) instead: http://www.8052.com/forum/read.phtml?id=64877 http://www.8052.com/forum/read.phtml?id=43575 Jan Axelson has an article comparing & contrasting different serial interfaces: http://www.8052.com/forum/read.phtml?id=25430 Russell Bull said:
SPI is a trademark of National Semiconductor. Are you sure? I thought it was Motorola? Isn't Microwire National's? Russell Bull said:
Some clock on the falling edge, some on the rising edge. It always pays to read the datasheets The data sheet in this particular case describes an interfaces that's clocked on both edges: http://www.8052.com/forum/read.phtml?id=74824 |
