i posted this here now because i am new to this forum and accidentally posted on another thread and got severely flamed.
i use the processor PSD3233QAT-RF
i've got a question about i2c function. 1) is it true that i can set any fixed baud rate (clock) from 0 to 100KHz? 2) if i set the bit I2CFREQ, what value should i put into the register if i'm using crystal 4MHz? 4) if i set the bit I2CFREQ2,SMP=0, is the baud rate fixed to 400KHz or i'm free to set any baud rate from 0 to 400KHZ? what value should i put into I2CADD then using a 20MHZ crystal?
answers are appreciated. Thank you.
IIC does NOT have a 'baud rate' it does have a 'bit rate'

erik,
thank you for the helpful reply. i was starting to wonder if the only responses i would get here were from flamers!!!
ps; yes i understand what you say aboot baud rate and iic
beware that if your device is SMB, not IIC (sometimes you will se things misnamed) there IS a minimum speed.
sorry about posting as afterthoughts, it is early here.
What flamers? Getting a response telling you that you have done something wrong - or haven't specified all required information - is not flaming.
Would you prefer that people lie to you? Maybe we should assume any random chip, and give answers specifically for the chips _we_ uses? Would that make you happy?
When your internet cable is smelling sulfur, you will know that you are being flamed ;)
