What’s new on the X2?

What’s new on the X2?

Well what I can see a couple of things that excite me.

Updating program slots from i2c EEPROM and running additional code from external i2c EEPROM.

Booti2c
Readrevision
Run slot
#slot number
Select the internal program slot (1-4) or i2c program slot (5-8) on X2 parts.
#revision number
Set the user program version (1-254) on X2 parts.
#slot1file “filename” Programming Editor Only
#slot2file “filename” Programming Editor Only
etc.
Include the filename of other slots (1 to 8) for simulations (X2 parts).
Example: #slot1file “c:\test.bas”

And these additions to name a few.

HSERSETUP
Mode is a variable/constant whose bits specify special functions:
bit0 - background receive serial data to the scratchpad
bit1 - invert serial output data (0 = ‘T’, 1 = “N”)
bit 2 - invert serial input data (0 = “T”, 1 = “N”) (X2 parts only)

flag0 hint0flag X2 only - interrupt on B.0
flag1 hint1flag X2 only - interrupt on B.1
flag2 hint2flag X2 only - interrupt on B.2
flag3 hintflag X2 only - occurs when any of 0,1,2 has occurred

PICAXE-28X2, 40X2 parts have 1024 scratchpad bytes (0-1023)

new features with X1 and X2 parts

And . . . . .

maybe by the time the X2 parts are on the shelf,

the use of brackets for some mathematical precedence will come to fruition for the X1 parts

On X1 and X2 parts it is possible to enclose part equations in brackets e.g.

let w1 = w2 / ( b5 + 2)​

Recall it being stated by Technical that this was just a case of getting the Programme Editor amended not an issue with PICAXE firmware
