MSP430G2553 I2C Interface help required

Recommended Posts

Hi all,

 

I would like to interface an I2C ADC (PCF8591) for one of my application. I have tried a lot with the sample programs. But still my launchpad is not even generating the clock pulse.

 

Can anybody help me.

Did you use Energia? Did you enable pull up or have external pull up resistors? Did you try without the target I2C slave attached? Do both devices accept the same voltage? Which sample programs did you try?
