Hello in my project i want to read with my arduino nano a analog value with a mcp3221 over i2c and one DS18B20 on pin 2. If i only read the mcp or the DS18B20 alone, it works but if i read 18B20 and start with wire.begin() the mcp3221 i can't get the DS18B20. If i don't start the i2C bus it is work. After activate the i2c bus it doesn't work.
What is the problem? Can't handle the arduino both buses(oneWire and i2c)? Thanks
