This is standard JSON notation, so if you are not familiar with it, Google is your best friend. Be aware that the '...' means you can have as many entries as you want, it's not part of the syntax. Every section is optional, but it does not make sense to set i2c in the 'dac_config' parameter and not setting anything here. The parameter 'mode' allows to *or* the register with the value or to *and* it. Don't set 'mode' if you simply want to write. **Note that all values must be decimal**. You can use a validator like [this](https://jsonlint.com) to verify your syntax
