Atmega/LED Driver?

Good day.
There are:
* Atmega32
* 8 RGB LEDs (or 8 * 3 = 24 LEDs)
Why such a question, tell me the LED driver that can control 24 channels at once (adjust their brightness, PWM). It is desirable to have libraries for this driver in C for Atmega16/32. Perhaps one of the mandatory requirements is accessibility and popularity.

Well, who knows what exactly is available and popular with you?
TI: TLC5947, TLC5951, TLC5952 - small pack
NXP: PCU9656 etc.
ON Semi: CAT4016-like.
Maxim also has a line
and ische a lot of things
. Large manufacturers have their own lines, so the catalog of a local store is in hand :) By the way, don't bother with 24 channels especially. Most drivers communicate over protocols like I2C, so getting 3x8 (one per channel) might be easier in terms of wiring and image processing.
