No, I utterly refute that, Robin2.
I would say that the datasheets are not a useful resource for most users here - most will find the link, take a quick look and conclude tl,dr.
Their sheer length and detail is likely to be overwhelming to the average noob, and they need a particular skill-set to interpret.
For example - a number of times it has been necessary to dispel the myth that a HIGH is anything above 0.6V, because in the "Electrical Characteristics" it quotes
Input High Voltage, except XTAL1 and RESET pins VCC
= 1.8V - 2.4V 0.7VCC
= 2.4V - 5.5V 0.6VCC
People see the 0.6V, and miss the "CC
Believe me, I have no vested interest in being some High Channeler of the Atmel Truth, but I'm a great believer in a little knowledge is a dangerous thing, and unless you're equipped to, and capable of, reading a processor datasheet, you're going to be a very dangerous person indeed.
If you want detailed debate of the fine-detail and ins-and-outs of AVR, take it to AVRfreaks.
Prove me wrong by adding a page to the Reference section that has direct links to the key Atmel datasheets
I'm a forum moderator; I no access to, or interest in, the Reference section.
