[nos-bbs] KISS help...

[jerome schatten]

Thanks Michel... that's good to know. I see my 5v supply voltage at
tp1/tp2 is only 4.7 volts (on two dvm's), and that's in no-no land, so
I'm gonna put a lab grade power supply on it and see what happens. The
pi is apparently very sensitive to the 5v line being too low. I shall
report back.
