OneWire ds(3); // on pin 3
//int deviceaddress = 0x50;
int deviceaddress = 0x52;
int addr=0; //first address
int ledPin = 13;
int val = 0; // variable to store the read value
There’s more to that code I can post if someone thinks it might help, but I don’t even know if the “ds” in the code and the “ds” on the board are related. I simply don’t have enough experience with coding.
Trace out the circuit - what is the other end of that resistor-like thing, and the other pins on the transistor-like thing connected to? That - and the datasheet for the parts that are on the board - will probably point you in the right direction.
Thanks again! All EEPROM address pins are grounded. Looks like 3K3 pullup for I2C. I hope after adding this one and an ADS1115 breakout (10K pullup) and a 10DEF board (unknown pullup), the I2C pullup won't be too small
