#162935 - backlight led Responding to: ???'s previous message |
it was given in data sheet that 4.2v is required for the back light led but no mention of the current requirement.
hence please advice me about the current requirement. A normal LED of 4.2V rating requires about 10mA at least. so do i need to assume that it is 10mA? by the way sorry for my previous post.. its actually a program mistake. I forgot to keep the RW pin low! |
