NAME

       mesa_pktgyro_test - PktUART simple test with Microstrain 3DM-GX3-15 gyro

SYNOPSIS

       loadrt mesa_pktgyro_test [count=N|names=name1[,name2...]]

DESCRIPTION

       This  component  is  written  in  order  to test the PktUART driver for Mesa. It resembles
       partly Andy Pugh's mesa_uart.comp .

       This module uses the names= mode of loadrt declaration to specify which PktUART  instances
       to  enable. A check is included to ensure that the count= option is not used instead.  For
       simplicity we test only one PktUART instance, therefore load the component like this:

        loadrt mesa_uart names=hm2_5i25.0.pktuart.0

       The PktUART instance names are printed to the  dmesg  buffer  during  the  Hostmot2  setup
       sequence,  one  for each PktUART instance included in the bitfile loaded to each installed
       card during the Hostmot2 setup sequence. Type "dmesg" at the terminal prompt to  view  the
       output.   If  you  want  to  work with more than one PktUART instance, consult Andy Pugh's
       mesa_uart.comp

       In order to compile and install do:
        halcompile --install src/hal/drivers/mesa_pktgyro_test.comp

       The component exports only one function, namely receive, which needs  to  be  added  to  a
       realtime thread.  To test this component  set DEBUG=5 before and execute this HAL script:
        loadrt hostmot2
        loadrt hm2_pci
        loadrt mesa_pktgyro_test names=hm2_5i25.0.pktuart.0
        loadrt threads name1=test1 period1=10000000
        addf hm2_5i25.0.pktuart.0.receive test1
        start

       Check linuxcnc.log for debug output.
