Hello,
i was looking at the ads1219 datasheet, and it is stated that before an i2c transaction a high to low on the SDA line while SCL is high is a most to initialize a start operation, however, my question is that an alternative of the start command. Moreover, i would like to know the size and format of the ACK and NACK sent by the device. Last if i want read the status register,
is the following steps correct
i2c start
i2c set ADC by reset pin high to low
send the device (if select pins are both ground i sent 0x40)
release i2c bus, should i get an ack message or send the the command 0x20
should i get ack here again ?
thanks for the help
