Hi friends,
1- Does someone knows if these i2c boards can be used in the same i2c bus?
INA219 High Side DC Current Sensor Breakout - 26V ±3.2A Max
ADXL335 - 5V ready triple-axis accelerometer
BMP085 Barometric Pressure/Temperature/Altitude Sensor
DS1307 Real Time Clock breakout board
they dont have configurable pins i2c address like:
ADS1115 16-Bit ADC - 4 Channel with Progrmmable Gain Amplifier
2 - Does someone knows about add one more "simulated" (but funcional) I2C port in Raspberry pi?
Thanks

Re: I2C address
They all have different I2C addresses, except for the ADXL335, which is not an I2C device:Luc wrote:1- Does someone knows if these i2c boards can be used in the same i2c bus?

INA219 : address 0x40
BMP085 : address 0x77
DS1307 : address 0x68
ADXL335 - three analog outputs.
All three can be used on the same bus.
I have not done this. Someone else may know.2 - Does someone knows about add one more "simulated" (but funcional) I2C port in Raspberry pi?

Re: I2C address
a while back phil burgess wrote about an i2c bus embedded in the hdmi interface. wonder if that can be gotten at on the pi.

Re: I2C address
During my Raspberry Pi reading, someone posted about nullifying one of the I2C lines (Voltage? Ground?) into an I2C device to enable multiple I2C devices with the same address on the same bus. You'd tie up a GPIO port for each I2C device with a conflicting port, but you should be able to do it.
