FullDuplexSerial Strings Containing Variable

coryco2

I would like to use FullDuplexSerial's Str method to send a string of long-sized values that include both fixed numbers and variables, e.g.

serial.str (string( $01, $02, variable3, $04 ))

but the compiler doesn't like the variable in there, even proceeded by an "@". Why not? Is there any way to make this work?

Strings must be constants.

You must use "dec" to send variables.

serial.dec(variable3)

No. STRING() produces constants, so the strings can't have variable information in them. Sure, you could incorporate the address of a variable in a constant string since the address itself is constant, but the .str() code just looks for a zero byte and transmits everything else.

If you're trying to send people-readable numbers (a sequence of digits), use the .dec() method. If you want to send the content of a long variable as a sequence of 4 bytes, you'll have to use .tx() or write your own routine that then calls .tx() like this:

PRI sendFour( value) | i
   ' Send a long as 4 bytes lsb..msb
   repeat i from 0 to 3
      serial.tx(value.byte[ i ])
