Thread: IREAD instruction
face picon face BY : James Newton, webmaster email (remove spam text)


What is the date code on the SX52? Some older versions are not
supported with the SX-Key Rev E.

Is the failure reliable? If not, it may be a communications
failure between the SX-Key and the PC or excessive noise or bad
connection between the key and 52. I've seen a lot of "strange"
things with SX-Keys.

Try a test program that counts up a register from "A" and
compairs it with the data from the IREAD and turns on an LED if
they don't match, then run it off the SX-Key. If it works,
consider replaceing the SX-Key with rev F (latest) from Parallax
Inc or switch to the SX-DEV.
