32xan 1 Posted March 31, 2013 Share Posted March 31, 2013 I'm working in project where few MSP430G2* and i2c-ready ADC/DAC are doing I2C communication. While the DAC/ADC have proper open-drain SDA/SCL, I don't find a way to operate MSP430G2* with open-drain output while software bit-banging ports P1.6 and P1.7. So, did I miss some details in SLAS722/SLAU144 and msp430g2 could operate honest open-drain (as in opposite to manipulate P1DIR. while keeping P1OUT. low, that how I'm doing now)?
