How to read/write variables in Byte data type?

<< < (2/6) > >>

Support:

--- Code: ---Send_Buf[0] = CHR(&H2)
Send_Buf[1] = CHR(&H6)
Send_Buf[2] = CHR(&H4)
Send_Buf[3] = CHR(&H1)
Send_Buf[4] = CHR(&H22)
Send_Buf[5] = CHR(&H10)
Send_Buf[6] = CHR(&H0)
Send_Buf[7] = CHR(&H0)
FOR i = 0 TO 6
  Send_Buf[7] = Send_Buf[7] XOR Send_Buf[i]
NEXT

PRINT ASC(Send_Buf[7]),"\n"

--- End code ---

jrs@laptop:~/sb/test$ scriba mytest2.sb
48
jrs@laptop:~/sb/test$

Does your VB code return the same value as above?

The rest is simply opening up a socket and using PRINT and INPUT to communicate with the device.

Fouad_msb:
the value is 51.
I think it should be converted to decimal before XOR loop.

Support:

--- Code: ---Send_Buf[0] = &H2
Send_Buf[1] = &H6
Send_Buf[2] = &H4
Send_Buf[3] = &H1
Send_Buf[4] = &H22
Send_Buf[5] = &H10
Send_Buf[6] = &H0
Send_Buf[7] = &H0
FOR i = 0 TO 6
  Send_Buf[7] = Send_Buf[7] XOR Send_Buf[i]
NEXT

PRINT Send_Buf[7],"\n"

--- End code ---

jrs@laptop:~/sb/test$ scriba mytest3.sb
51
jrs@laptop:~/sb/test$

My error, I shouldn't have converted it to a character value first.  :-\

Fouad_msb:
it works fine. thanks a lot :)

I have another question, how to make a timer! without stopping the program sequence?
I tried to make a loop, but it will not go to then next step.

I need to pull the data every 3 sec, in the same time that will not affect the other commands like which need to send it to the device.

for example, I have a thermostat which need to read the temperature every 3 sec, and in the same time I can send or change the setpoint by sending a command to the device.

thanks a lot. I reall appreciate your support.

Support:
ScriptBasic doesn't support timers like VB so you may have to be a little creative with this. You have a few ways to approach this.

1. You could create a MAIN routine that checks NOW and runs a set of SUBs/FUNCTIONs and SLEEPs when there is nothing to do.

2. Create two scripts. One that polls devices as gets info and write it to a file. The other script would process the file on a first in first out basis.

3. Create an extension module with a true timer and access your device from the extension module.
