Ctrl Command read_analog_in
Function Reads in the analog input values:
• ANALOG IN0 and ANALOG IN1 at the “McBSP/ANALOG” socket connector of the
RTC6 PCIe Board
• ANALOG IN0, and ANALOG IN1 at the SPI/ANA/UART Socket Connector of the
RTC6 Ethernet Board
Returns them as 12-bit digital values.
Call AnalogValue = read_analog_in()
Result As an unsigned 32-bit value.
Bit #0
…
Bit #11
ANALOG IN0 input value as 12-bit digital value.
Bit #12 = 0. Channel number.
Bit #13 = 0.
Bit #14 = 0.
Bit #15 Old bit for ANALOG IN0.
Bit #16
…
Bit #27
ANALOG IN1 input value as 12-bit digital value.
Bit #28 = 1. Channel number.
Bit #29 = 0.
Bit #30 = 0.
Bit #31 Old bit for ANALOG IN1.
Comments • See also Section ”Analog Input Ports”, page 86.
• read_analog_in sets the old bits (Bit #15 and Bit #31) to 1 after reading.
As soon new data are available at the corresponding analog input they are
automatically set to 0.
• The analog input values (ANALOG IN0 and ANALOG IN1) can be recorded by
set_trigger/set_trigger4/set_trigger8 (signal 54). However, the old bits (Bit #15 and
Bit #31) are not recorded. The format of the data is
((ANALOG IN1 << 16) + ANALOG IN0).
RTC4RTC6 New command.
