mesa_pktgyro_test - PktUART simple test with Microstrain 3DM-GX3-15 gyro
loadrt
mesa_pktgyro_test [count=
N|names=name1[,name2... ]]
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.
