mx6sx simple i2c write function

dscott_ueidaq — Fri, 26 Aug 2022 14:19:56 GMT

I need to output a 16-bit value to a single i2c device at boot time.

A simple polled write with no interrupts or dma is all I need.

This will be on a mx6sx using i2c4.

Is there an example that you could point me to?

I hope you are doing well.

You can use i2cset and i2cget Linux commands. Please find the reference from below.

To write the data: i2cset -y <I2C Bus No.> <Slave address> <Offset> <Data>

To read the data: i2cget -y <I2C Bus No.> <Slave address> <Offset>

Thanks & Regards
