#89624 - Its really very high. Responding to: ???'s previous message |
Suppose i've to take 8000 to 10000 samples/second of some signal and give it to micro. using I2C and this is almost continuous operation, say some process monitoring/control, whats better hardware/software I2C ? With 100KHz I2C data rates of 8000 to 10000 samples / second are really very high the maximum data rate supported at 100kHz is 11111 samples/second. Thus if you do 10,000 samples/second with soft I2C your processors 90% time will be consumed by I2C routines. If you can manage rest all work with 10% processors utilisation use soft I2C else use Hard I2C with hard I2C you will hardly need any processor power for I2C stuff. Regards, Prahlad Purohit |

| SW-I2C mostly sufficient ! | 01/01/70 00:00 | |
| similar CPU load?? pray explain | 01/01/70 00:00 | |

| how do you do soft IIC with 1% load | 01/01/70 00:00 | |

| Peters 1% | 01/01/70 00:00 | |
| very high data rates?? | 01/01/70 00:00 | |
| consider the whole program ! | 01/01/70 00:00 | |
