I failed so far to connect the external ADC via I2C interface to my S3 (no touch) . Tried to use Pins 43/44 and 17/18... but It does not find any I2C....
my code:
... ADS1115_lite ads(ADS1115_ADDRESS_ADDR_SDA); // 0x4A (my Addr pin is connected to SDA for this 0x4A address) pinMode(17,INPUT_PULLUP); pinMode(18,INPUT_PULLUP); Wire.begin(17, 18); //SDA, SCL ...
if I measure with the oszillocope on 17/18 I dont see any signal than high.
What am I doing wrong??
