String to value

geokonst

Hey everybody. Sorry to bother again.
I am trying to send a decimal variable 0-255 as a two digit hex over serial.
Any ideas why the following code won't work?

CON
  _clkmode = xtal1 + pll16x                             
  _xinfreq = 5_000_000                                  

VAR
   long af          
OBJ
    serial : "Extended_FDSeriall"
      convert : "simple_numbers"
PUB main 
af:= 23
Serial.Start(31,30,%0000, 115200)

 repeat 
          af:= convert.ihex ( 243,2 )
          
          serial.hex (af,2)

I get 35 and 38 and when I change to serial.str I get the right number ($F3) but in ascii.

hippy

I haven't looked at 'simple_numbers' but I'd guess convert.ihex() converts what you give it as a number to a string and a subsequent serial.str prints that string.

Using serial.hex(af,2) converts a number in af and sends it as two hex characters so there's no reason to call convert.ihex() before it.

  ' Transmits "00", "01", .. "FE", "FF"
  repeat af from 0 to 255
    serial.hex(af,2)

Hippy you were right. I guess I was too tired at that point. Thank you and sorry for not thanking earlier [noparse]:)[/noparse]
