ΜMIC.200

This module uses the library provided for the µMIC.200. You need the umic_dio.h, umic_relay.h and umic_led.h headers and also the umic.so library to be present in your system and accessible by the compiler.

The parameters should be the type and its number separated by a dot:

TYPE.NUMBER

NUMBER depends on TYPE, where TYPE can be (all are in lower case):

  1. led: controls the LED1-4 of the µMIC.200 (Only QX can be used with led). The possible numbers for NUMBER are from 0 to 7 according to the table below:

    • 0 → LED1_GREEN

    • 1 → LED2_GREEN

    • 2 → LED3_GREEN

    • 3 → LED4_GREEN

    • 4 → LED1_RED

    • 5 → LED2_RED

    • 6 → LED3_RED

    • 7 → LED4_RED

      Example:
      led.4 → controls the LED1 color red

  2. dio: controls the 8 digital I/O at pins 5-12. Number can be from 1 to 8. Use IX to make it input, and QX to make it output.

    Example:
    dio.3 → will access Digital I/O 3 at pin 7 of the µMIC.200

  3. relay: controls the relays. The possible numbers are 1 and 2. The 1 controls the NO relay and 2 the NC. Only QX can be used with relay.

    Example:
    relay.1 → will control the NC relay at pins 14- 15

Important
Using the Releays

To use the relay and led, in some cases you might have to change some header files in your µMIC.200. You need to find the files /usr/include/umic_led.h and /usr/include/umic_relay.h and add two things:

  • At the beginning, right after the first #define add:

    //----------------------------------------------------------------------------//
// take precautions if compiled with C++ compiler #ifdef __cplusplus
extern "C" \{ #endif
//----------------------------------------------------------------------------//

  • And at the end, right before the last #endif, add

+
//----------------------------------------------------------------------------//
#ifdef __cplusplus } #endif // end of C++ compiler wrapper
//----------------------------------------------------------------------------//

+ If you don’t want to use the relay and led, or you don’t want to change the header files, go to ~/org.eclipse.4diac.org/src/modules/umic/processinterface.h and set the definitions of UMIC_LED_ENABLED and UMIC_RELAY_ENABLED to zero.
