I could see LTC4261 chip can be programmed with I2C. Is it programmable with arduino nano?
My question is how were you directed to this forum for an LTC4261 related questions?
On the FPGA reference designs we do not have support for the LTC4261 and clearly not for arduino.
We don't have the resources to help you regarding your topic on this forum. Go to analog.com and search for LTC4261 -> support.
That being said, my opinion is if arduino is capable of i2c. Yes you can communicate with the LTC4261, you just need the software/code to do so.
