  • Page 5: Important Safe Handling Information

    Always store this product in ESD-protective packaging when not in use. Safe Handling Precautions The Hercules III SBC contains a high number of I/O connectors with connection to sensitive electronic components. This creates many opportunities for accidental damage during handling, installation and connection to other equipment.
  • Page 6 The same situation can occur when pulling a ribbon cable off of a pin header. If the pins are bent too severely, bending them back can cause them to weaken unacceptably or even break, and the connector must be replaced. www.diamondsystems.com Hercules III User Manual Rev A.2 Page...

  • Page 66: Analog-To-Digital Input Ranges And Resolution

    Overview Hercules III uses a 16-bit A/D converter. The full range of numerical values for a 16-bit number is 0 - 65535. However, the A/D converter uses two’s complement notation, so the A/D value is interpreted as a signed integer, ranging from –32768 to +32767.

  • Page 67: Performing An A/D Conversion

    A/D if AINTE = 0 (interrupts are disabled). When AINTE = 1, the A/D can only be triggered by the on- board counter/timer or an external signal. This protects against accidental triggering by software during a long- running interrupt-based acquisition process. outp(base,0x80); www.diamondsystems.com Hercules III User Manual Rev A.2 Page...

If you write your own software or interrupt routine you should conform to the described behavior for optimum results.

  • Page 71: Digital-To-Analog Output Ranges And Resolution

    16.1 Description Hercules III uses a 4-channel 12-bit D/A converter (DAC) to provide four analog outputs. A 12-bit DAC can generate output voltages with the precision of a 12-bit binary number. The maximum value of a 12-bit binary number is 2 - 1, or 4095, so the full range of numerical values that the DACs support is 0 - 4095.
