I have built a data logger using snippits gleaned from this forum. It works ok.
Setup is 18X/axe033/24lc256/3.3v regulator/ 4 x nicads..
Although i can display the correct readings on the LCD and using debug, ie 3.3v = 255, using a digital voltmeter the supply is 4.5v.
LCD is connected to nicads. So no rocket scientists required. Pullups are coonected to 4.8v.
Possible answer:- zap 2 x 4k7's on 033. put 2 x 4k7's next to 18x, ie 3.3v.
Has anyone tried this, if so which ones are they on the 033. There are 3 x 4k7's.
Tracks difficult to follow and I would need to unsolder the serial to look underneath.
Can't find any info if I do a search.
