Thought I would create a new thread for the Armmite H7 as I've had a few minutes to work on it. I'll post updates to this thread as they occur and please use it for comments/bug reports etc.

This release supports the normal range of MM+/MMX file handling functions (I hope!!!)

Pinout is fixed:

SD-CS = PF6
SD-CLK = PF7
SD-MISO = PF8
SD-MOSI = PF9

These pins are not available for any other use and there is therefore no associated "OPTION" command needed.

The software automatically detects insertion and removal of a card and will deal with this appropriately. There in no requirement to connect anything to the card-detect output from the sdcard slot

Performance has also been increased significantly
