looking for simple example

[Anonymous]

Hi I'm looking for a simple example of reading a byte at a time from a serial port. Currently I have a stream of bytes coming in with no return line, so I'm wanting to add that myself. I'll basically need to read each byte, then calculate a checksum and check the next byte if it's a checksum. If it's a checksum then insert a return line, if not I need to keep adding and checking for a valid checksum.

Thanks,
Travis

Hello Stefan,

what a nice name. I want use script Communicator to communicate with an handheld device. The used communication gives an echo of each Byte. So I have to send single Bytes. For example:
-> 0x18
<- 0x06
But this are only single Bytes. If I use sendString('0x18'), the terminal sends 30 78 31 38
If I use var Feld = Array(0x18); and sendDataArray(Feld) , the Terminal sends 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

I Just want a single 18.

Thanks,

Stefan

Hi Stefan

yes a really nice name :-).
If you use sendString('0x18') then you send the string 0x18 (4 characters). If you create an array with Array(0x18) then you create an empty array with the size of 18 (empty) entries.

If you just want to send a single byte you have to do this:

var data = Array();
data[0] = 0x18;
sendDataArray(data);
