Data on SD card going from path planing software - closed for me.
My task - read first way point lat. and long. and when i reach this way point - increase index and repeat.
And i need write way point in other file with equivalent format - this is for movement reconstruction...
In one time moment i have in memory of my board MCU - a current way point index, lat. and long. Thats it.
Total not more that 1000 way point records can be in one file.
