Re: Problems about Streamdevice when sending hex command to motor device

[Dirk Zimoch <dirk.zimoch@psi.ch>]

Hello 李姣赛,

The default FTVL value for aai, aao and waveform records is STRING. But 
an array of 40 character Strings is almost never what you need. And 
STRING cannot be formatted with %x.
Use: field (FTVL, "CHAR")

Also your aai and aao records have no NELM. The default value is 1. Thus 
you can only write one array element to it. Set NELM to the maximum 
bumber of bytes you need, for example:
field (NEML, "20")
