Aha!
Have stuck a scope on the damn thing, it revealed one solitary spike to 5V, followed by a mediocre decline to about 2.
Consulting the oracle (a.k.a. the fecking datasheet) revealed all...
The PCF8574 is a pseudo bidirectional port. Just like the 8051 ports that we all know and love(?).
You get about 30us of strong pullup, followed by a weak pullup of between 30 & 300uA.
Which does bugger all for the octal darlingtons that it's driving.
The addition of 32 4k3 resistors in R1206 sm packages as pullups to 5V has increased the light output from barely visible to dazzling.Comment
