@N thanks Nicklas .... with your suggest I understand a little better the
code ... these is myne renewed (and more complete than the last one ... I
have not entered the tedious and useless functions to understand the
problem here ... but if I can finish the job for January (when my holidays
are over) I will post the complete project on the forum:
using namespace std;
static RCS_CMD_CHANNEL *emcCommandBuffer = 0; /* I've declared
'emcCommandBuffer' as "static" ... seems these is not right */
static RCS_STAT_CHANNEL *emcStatusBuffer = 0;
EMC_STAT *emcStatus = 0;
static NML *emcErrorBuffer = 0;
static char error_string[NML_INTERNAL_CMS_ERROR] = "";
static int emcCommandSerialNumber = 0;
int counter = 0;
void QtDro::run()
{
double thX = 0;
double thY = 0;
double thZ = 0;
double thA = 0;
double thB = 0;
double thC = 0;
double thU = 0;
double thV = 0;
double thW = 0;
QTextStream(stdout) << "First run function" << endl;
const char *nmlfile =
"/home/bkt/linuxcnc-dev/configs/common/linuxcnc.nml";
RCS_STAT_CHANNEL *stat = new RCS_STAT_CHANNEL(emcFormat, "emcStatus",
"xemc", nmlfile);
RCS_CMD_CHANNEL *cmd = new RCS_CMD_CHANNEL(emcFormat, "emcCommand",
"xemc", nmlfile, 0);
NML *error = new NML(emcFormat, "emcError", "xemc", nmlfile);
while(1)
{
if((stat->peek() != EMC_STAT_TYPE) || (!stat->valid()))
{
QTextStream(stdout) << "while these program NOT run " <<
endl;
break;
}
else
{
EMC_STAT *emcStatus =
static_cast<EMC_STAT*>(stat->get_address());
if ((thX != emcStatus->motion.traj.position.tran.x) || (thY !=
emcStatus->motion.traj.position.tran.y) || (thZ !=
emcStatus->motion.traj.position.tran.z))
{
thX = emcStatus->motion.traj.position.tran.x;
thY = emcStatus->motion.traj.position.tran.y;
thZ = emcStatus->motion.traj.position.tran.z;
thA = 0;
thB = 0;
thC = 0;
thU = 0;
thV = 0;
thW = 0;
emit thXYZABCDEF(thX, thY, thZ, thA, thB, thC, thU, thV,
thW);
}
if(counter>=50 && counter<51)
{
QTextStream(stdout) << "state_msg try zone" << endl;
EMC_TASK_SET_STATE state_msg;
QTextStream(stdout) << "spy 1" << endl;
state_msg.state = EMC_TASK_STATE_OFF;
QTextStream(stdout) << "spy 2" << endl;
state_msg.serial_number = ++emcCommandSerialNumber;
QTextStream(stdout) << "actual value of state_msg: " <<
state_msg.state << endl;
QTextStream(stdout) << "these steps seems right .. now
try to write" << endl;
cmd->write(&state_msg);
// emcCommandBuffer->write(&state_msg); /* these NOT work
because not declare 'emcCommandBuffer' with automatic memory allocation
with macro "new" */
QTextStream(stdout) << "just write on emcCommandBuffer"
<< endl;
}
counter++;
}
this->msleep(100);
}
}
At these point terminal reply to my good news:
bkt@bkt:~/linuxcnc-dev$ QtDro
argc: 1 argv: 0x7ffd462f8b98 nmlfile:
First Application Start ok
First run function
state_msg try zone
spy 1
spy 2
spy 3
actual value of state_msg: 3
these steps seems right .. now try to write
just write on emcCommandBuffer
But on Axis Gui SIM that I use as test gui, nothing change ....
how can I understand if Lcnc actually had my command? (Axis is active
and on on .... after the EMC_TASK_STATE_OFF command I expected the
button toggle to go OFF ... maybe launch the wrong command?)
regards
