Hi
I want to use the i2c in 3.3 volts how do we configure that, current configuration is as below
pinctrl_i2c1: i2c1grp {
fsl,pins = <
MX8MM_IOMUXC_I2C1_SCL_I2C1_SCL 0x400001c3
MX8MM_IOMUXC_I2C1_SDA_I2C1_SDA 0x400001c3
>;
};
Regards

Solved! Go to Solution.
Can you let us know if you are using iMX8MMini EVK or custom board?
If it is EVK we can see from the schematic that I2C1 is on 1.8V, so to make it work on 3.3V you need to use an external level translator or use I2C2 or I2C3.
