I’m using i2c-tools on a small linux device to try to write data to a Dash i2c slave. On the slave, I am using the Wire.h library. My problem is that my write command requires 3 paramters: i2c bus (which i know), device address (which can be set with the begin() function ) and lastly the internal DATA REGISTER address, which leads to my question: Where can I find documentation for what this address number is?
I tried looking in the MK22FN1M0VLH12 Microprocessor datasheet and couldn’t find anything in there. Is there a function I can run on the Dash side of thing to find the address of the i2c rx_buffer?
