If you are using the SX48 and the PWM command with SX/B version 1.51.03 you will get an assembly error.
To correct the error add these lines to your program in the constants section.

__TRISA CON __TRIS
__TRISB CON __TRIS
__TRISC CON __TRIS
__TRISD CON __TRIS
__TRISE CON __TRIS

Thanks to user "djh82uk" for bringing this to my attention.

In SX/B version 1.51.03 if you attempt to use a WORD variable as an array index you should get an error message (usually incorrect number of parameters). But the SEROUT command does not issue an error. In fact it will send the address of the array instead.

DEVICE SX28, OSCXT1, TURBO, STACKX, OPTIONX, BOR26
FREQ 4_000_000
 
sendStr  VAR BYTE(11)
temp     VAR WORD
 
PROGRAM Start NOSTARTUP
 
Start:
  PUT sendStr, "HELLO THERE"
  FOR temp = 0 TO 10
    SEROUT RA.0,T9600,sendStr(temp) ' DO NOT USE A WORD AS AN ARRAY INDEX
  NEXT
END

The "fix" is to just use the LSB of the word variable.

DEVICE SX28, OSCXT1, TURBO, STACKX, OPTIONX, BOR26
FREQ 4_000_000
 
sendStr  VAR BYTE(11)
temp     VAR WORD
 
PROGRAM Start NOSTARTUP
 
Start:
  PUT sendStr, "HELLO THERE"
  FOR temp = 0 TO 10
    SEROUT RA.0,T9600,sendStr(temp_LSB)
  NEXT
END

When using the unary operator '~' with an array element bit, the unary operator will be ignored.

myBit = ~myArray(1).1 ' The ~ is ignored (actually the value is inverted twice)

You cannot use "-" in data values.

For example "DATA -1" will read as "1" instead of "-1".

One workaround is to define a constant and use that in the DATA statement.

NegOne CON -1
DATA NegOne

When using the "_TO" (watchdog timeout bit) variable you get error message "Symbol <_TO> is not defined".

If you need to use the "_TO" variable add this line to your variables section:

\_TO EQU TO

Note the slash and underscore prefix.

When using a WORD variable as the timeout parameter in SERIN, the timeout value does not get loaded into the __PARAM1 and __PARAM2 variables.

Either use a BYTE variable for the timeout parameter or put this line just before the SERIN command

__WPARAM12 = timeoutWordVar + 256

This will load __PARAM1 and __PARAM2 with the correct values.

When using the LOAD command. The PROGRAM directive must be used before the end of any LOAD file.

What happens is that when the compiler comes to the end of the file that it is compiling, it checks to make sure that you used the PROGRAM directive (in case you missed it). But it also performs this check at the end of a LOAD file too.

To avoid getting this message, you need to have the PROGRAM directive either in the first LOAD file, or in the main program before the first LOAD file.

When using the SX28 the compiler will not use memory locations $F0,$F1,$F2,$F3,$F4 for arrays.

These locations CAN be used as single element arrays by aliasing the __RAM() array as such:

extra0 VAR __RAM($F0)
extra1 VAR __RAM($F1)
extra2 VAR __RAM($F2)
extra3 VAR __RAM($F3)
extra4 VAR __RAM($F4)

Did you know that 111,111,111 multiplied by 111,111,111 equals 12345678987654321 ?

Hey Bean,

Your link to SX/B 2.0 comes back as 404.

I realize the SX is at end of life;
I am in late stage of a design in progress,
and I need to complete it.

Is there a working link for SXB 2.0?
Is there a corresponding help file or other updated docs?

Thanks!
Mike
