What's new

  1. Direct data logging mode (WYGIWIS1))
    • Data received on the serial port is logged directly to a file
      • Files are named: LOGnnnn.TXT
      • Up to 1000 files will be created (this may change later)
      • Files are incremented on each boot
    • The mode is activated using setting “K”
      • S K 1 - sets the uMMC into data logging mode on next boot.
      • The setting remains until it is cleared.
    • Logs at any bit rate from 2400 bps up to 460800 bps
    • Escape from data logging mode by pulling “C” pin low
  2. New low power mode
    • Cuts power consumption in half, when idle
    • Expect less than 5 mA
    • RTC still runs, keeping time
    • Mode is activated with setting “Z”
      • S Z 1 - sets into low power mode.
      • The setting remains active until cleared.

Notes

Below is an example UMMC.CFG file (put it in the root of the SD card) to put the uMMC into data logger mode. The uMMC will automatically read the configuration and be in data logger mode.

e.g.:

  • 4800 bpsS D 6
  • data logger mode → S K 1
  • low power mode → S Z 1
