Hi everyone,
We are developing 100MeV LINAC vacuum control system through RS232 serial.
The hardware has a VIPC616 carrier and an IP-Octal-232. The software
includes drvSerial,drvAscii,drvIpac,drvVipc616, tyGSOctal and devAscii. The
first test was successfully with the help of Allan Honey and Steven Hartman a
few month ago.
But we have one problem. Some of the commands use the format
d.ddde-dd, but the OUT field of AO have to be specified as %e instead of %9.3e
or %.3e. So the value of AO will be sent as d.ddd000e-dd which doesn't meet
our requirement.
Does somebody meet the same problem? Is there any solution?
Any suggestion is welcome,
Lifang
