I've found a new bug in fat.c. Short file names are processed as if they have the type of the directory entry immediately before them, except if that entry is a long file name. Example: a sub-director ... |

To clarify "somewhat random", the time taken to perform the insertion sort will depend on the data it is sorting - the ADC readings. It will vary slightly, but probably not too much. Given t ... |

Just a comment that if I was going to do this, then I would use an insertion sort where the delay_us is (for a somewhat random delay), and change the array size to 12 to save a bit of RAM. The extreme ... |

There's no need for anyone to post a driver for the RTCC, it's built into CCS. See setup_rtc() and the various rtc_XXX() functions. |

#FUSES RTCOSC_INTis incorrect. You should be using#FUSES RTCOSC_T1The internal reference oscillates at 31kHz while the RTC expects a 32.768kHz reference and therefore expect to lose about (32768-31000 ... |

The idea with pullups is that they are generally intended to put a signal line into a default state when it isn't being driven. A higher resistor value means that when the line *is* driven, it doesn't ... |

No. What you're describing as "pull-up resistors" are actually divider resistors, designed to interface a 5V micro (Arduino) with the 3.3V SD card.

I've also checked your method of calling the function. The ",10" part of the parameters "(4096, 512, 10)" does not seem correct. That should be a pointer to a buffer. Your code sho ... |

I thinks there's some confusion between SPI and RS232. The #use SPI should not have baud=9600 (or any baud at all). |

At least part of the problem is that a web forum is a place for discussion, not a place for a code library.
A wiki would be a more appropriate place for a code library. The problem there is that it ... |

I don't know what mmcsd_read_ocr() does, but it is described as a "non-user function". I would ignore all "non-user functions" and just consider "user functions". mmcsd_c ... |
