Function Documentation

void logFlush

(

)

Write the contents of the temporary log buffer to the flash device.

If the buffer is empty, nothing is done.

Here is the call graph for this function:

uint32_t logGetAddress

(

)

Last used address in flash memory.

This location is where the next log data will be written.

Returns:

24-bit flash memory address
