I have connected a device with address 0x27 to the I2C bus. Since Omega2 has only one I2C, trying to access a bus other than 0 i2cdetect 1Įrror: Could not open file /dev/i2c-1' or /dev/i2c/1': No such file or directory WARNING! This program can confuse your I2C bus, cause data loss and worse!Ġ0: -ġ0: -Ģ0: - 27 -ģ0: -Ĥ0: -ĥ0: -Ħ0:. Please see if the i2cdetect reports ADC exp at either 0x48 or i2cdetect 0 , ADC exp can have 0x48 or 0x49 addresses(settable). If is is configure for gpio, change to omega2-ctrl gpiomux set i2c i2c Please verify that i2c pins are configured for i2c (not for gpio), in the omega2-ctrl gpiomux get "The Omega2 Dash is compatible with the existing ecosystem of plug-and-play Omega2 expansions." Still, going though various docs makes me believe that ADC Exp should work with Dash.
