- Description/Syntax/Arguments
- read
- reads data.
- data=read() data=read(NumberOfValues) data=read(NumberOfValues,DataType)
NumberOfValues is a scalar. Supported "DataType" values are 'string', 'double'
,'float', 'int8','int16','int32','int64','uint8','uint16','uint32','uint64'.
- write
- writes data.
- data=write(Data) data=write(Data,DataType) Supported type for "Data" is string, real number.
Supported "DataType" values are 'string', 'double'
,'float','int8','int16','int32','int64','uint8','uint16','uint32','uint64'.
- close
- Closes Serialport.
Examples
Read/write string data:
spobj=serialport();
spobj.read()
spobj.write('Hello serialport','string');
spobj.close();
Read/write numeric data:
spobj=serialport();
data=9;
spobj.write(data,'double');
out=spobj.read(1,'double')
spobj.close();
