In SX Microcontrollers, SX/B Compiler and SX-Key Tool, phipi wrote: I'm not sure if this will help or not, but I found an old Parallax errata sheet that contains some chip-specific info. I've attached a copy below. Also, the last SX18 chips I used in production had the following code: [b]    SX18AC75/DPES     AB9931AB[/b] As I recall, they worked to spec with my Rev E SX-Key without the need for workarounds. Although the SX28 and SX18 silicon is the same (I believe), these post-date the ones you've been offered by ten weeks and seem to carry a different rev code. -Phil ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=189735#m189748 Need assistance?
