Hi all, i am studying electronics, i would like to have some sample questions on finite state machine involve in the design of i2c, and the PWM role and functionality on i2c.
Thanks.
 

1. what is debouncing circuit in I2C? wht care should be taken for that?
2. What is the maximum distance of the I2C bus?
3. I'd like to extend the I2C bus. Is there something like a repeater for I2C?
4. Do I need to generate an ACK in read mode on the last byte? My chip starts sending data and occupies the bus...
5. Why does the SCL line have to be bi-directional?
6. How can I test / debug the I2C bus?
7. What bus speeds are available with I2C?
8. What is the maximum PWm frequency that can be generated using 8051...
9. what are the parameters dependent on pwm generation.
10. how do you vary the pwm in the code for different on off period?
