Print binary content of a variable to the serial port.
PRINTBIN var [ ; varn]
PRINTBIN #channel, var [; varn]
The variable which value is send to the serial port.
Optional variables to send.
The channel is optional and intended to be used with the OPEN statement.
PRINTBIN is equivalent to PRINT CHR(byteVar);
When you use a Long for example, 4 bytes are printed.
Multiple variables may be sent. They must be separated by the ; sign.
The number of bytes to send can be specified by an additional numeric constant. This is convenient when sending the content of an array.
Printbin ar(1) ; 3 ' will send 3 bytes from array ar() starting at index element 1.
Printbin ar(1) ; 2 ; ar(2) ; 4 ' will send 2 bytes from array ar() starting at index 1, then 4 bytes from array ar() starting at index 2.
When you use Printbin ar(1) , the whole array will be printed assuming that CONFIG BASE=1.
When you need to print the content of a big array(array with more then 255 elements) or with a data size that exceeds 255 bytes, you need to use the CONFIG PRINTBIN option.
When the CONFIG PRINT option is used for RS-485, the direction pin will be used by PRINTBIN as well.
When RS-485 is used, the following will happen :
- the direction pin is toggled
- all variables are transmitted
- a check if performed to ensure the last byte is transmitted
- the direction pin is toggled again
Dim A(10) As Byte, C As Byte
For C = 1 To 10
A(c)= c ' fill array
Printbin A(1) 'print content of a(1). Note that the whole array will be sent!
