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.
1) is it true that i can set any fixed baud rate (clock) from 0 to 100KHz? what you can set will be in the datasheet for your device. you can run any IIC device at 0.0000000001Hz to 100kHz, you can run most IIC device at 0.0000000001Hz to 400kHz you can run some IIC device at 0.0000000001Hz to 1MHz.
the answers to 2) and 3) will be in the fdatasheet for your device

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 ;)
