Qwiic OpenLog: How to set the "start position of each new read"?

In register 0x0A I should write a string of characters to change the start position of each new read.

It works, when I write 1 Byte after the command 0x0A. I can change the start position from 0 to 255. But files are bigger.

How to format the “string” with the offset value?

And where comes the “Start Position” command in the code? Before or after the “Read File” command.

It only takes the first char [0] as the startposition. The source of the firmware that is loaded on the QwiiC openlog can be found on https://github.com/sparkfun/Qwiic_OpenLog
