In SX Microcontrollers, SX/B Compiler and SX-Key Tool, TheBandit wrote: It may be entirely unrelated, but I am getting "Chip Connection Failed" about 4 out of 5 times when connecting the SX Blitz to my custom printed PCB which contains the above circuit. It's not the only circuit on the board, but it is the only one that applies voltage to any of the input pins while programming. When I connect my SX Blitz to the SX-Tech board containing one SX chip and no other circuits, it connects reliably every time. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=348367#m418519 Need assistance?
