[avr-gcc-list] output current for ATMega128 on output pins

Hi, i just browsed the data sheet but could not find in the electrical characteristics how much current i can output on a port. I'd like to drive some LEDs. I wonder, but this value should be in the data sheet, i must have missed it. Best regards, Torsten.

Torsten, AVR data sheets talk about 25 mA current per pin., but there is some limitation on the total current drawn. If you are planing to drive some LEDs (4/5) I think you can drive them directly from the port pins. You may consider sinking current to switch the LED ON rather than on sourcing
