    What is the analog input range and resolution, both in theory and in practice? I didn't see that detail in the Hardware Overview.

      Hi there, it sounds like you are looking for technical assistance. Please use the link in the banner above, to get started with posting a topic in our forums. Our technical support team will do their best to assist you.

      That being said, as listed in the datasheet, the microcontroller has a 10-bit ADC.

    Had all sorts of problems getting board to log under 10Hz. Above 10 no problem. One of my staff in desperation tried putting 01 (zero, one) i.e. "Frequency = 01" and now we can log at 1 Hz. Did some testing and found board was drawing 65mA logging at 1Hz on one A/D channel.

    When configuring the settings, make sure you set the correct pins. The configuration file does not directly match the Digital/Analog pins on the side of the Logomatic. Below is the list of hardware pins that relate to the configuration file:

    .
.
.
Digital/Analog Pin 8  = AD1.3
Digital/Analog Pin 1  = AD0.3
Digital/Analog Pin 2  = AD0.2
Digital/Analog Pin 3  = AD0.1
Digital/Analog Pin 7  = AD1.2
Digital/Analog Pin 4  = AD0.4
Digital/Analog Pin 5  = AD1.7 
Digital/Analog Pin 6  = AD1.6

    To log the temperature correctly into the microSD card you must have the correct settings for the Logomatic. Try these settings in the LOGCON.txt file when following the example hardware hookup:

    MODE = 2
ASCII = Y
Baud = 4
Frequency = 100
Trigger Character = $
Text Frame = 100
AD1.3 = N
AD0.3 = Y
AD0.2 = N
AD0.1 = N
AD1.2 = N
AD0.4 = N
AD1.7 = N
AD1.6 = N
Saftey On = Y

      When you repower the Logomatic without the USB connector attached, the board will start recording. The STAT0 AND STAT1 LEDs will start logging data.

    Is there a firmware mod that can include a timestamp with the serial data? I would really like that.

    I make a toy that sends serial data commands to an MP3 player.

    I would like to know when the different people use my toy in addition to knowing what buttons they press on my toy (what MP3 files they choose). Does anybody have a firmware option that does this?

    Thank you

    Are configuration settings made just by editing the configuration text file on the data logger? If so, what configuration settings are required to log the temperature sensor readings for the example shown? What does the logged data look like for this sensor and would it be possible to show an excerpt from the actual logged data file for this temperature sensor? What would it look like (just a general idea) for other analog inputs and for digital inputs if, as in the temperature sensor case, you do no up front processing, but just hook the sensor up to the Logomatic? Is it true that you can use up to ten sensors at one time? Thanks for your patience with a data logging rookie and for any help you can provide. I know that a foolish man can ask more questions than a wise man can answer. :-)
