Do i see it right, that there are 15 PWM outputs (2-13 + 44 45 46)? several sites of the shop do say, that there are just 14.  The 15 would be important for my project.

Nantonos, Nice Work on this!

May I use this on the http://ArduinoInfo.Info WIKI? I'd link back to your original as well.

Thanks!

A table of pins 1-100 on the Atmega2560 with the corresponding Arduino Mega pin number mappings would be ideal.

Hi there,

I noticed that the pdf drawing on the Arduino Product web page shows 2 crystals 16Mcs, however there's only one on the board??
Furthermore, the downloadable eagle files do not open in my Eagle: Invalid data error

I am experiencing communication probs, possibly coming from one clock source for the 2560 & 16U2, derived from 1 crystal, only.

Could you please clarify?

Thank's

Just out of curiosity does an Ethernet shield connect the same way and is just as efficient on the mega? Or must I get a new style of shield.  One other question would be does the mega have a sufficient amount of memory more than the Uno for SRAM that it would make a difference for a solid grouping of text for multiple strings in a program?

Thanks for posting this. That is a great reference to keep on hand.

This is a site which gives you pin-out of the various Arduino boards.

http://www.pighixxx.com/test

The "tripple x" in the site address does not mean it is a porn site except to show you the nakedness of the pins.
Hope it was of help.

Hi,

I am wondering which pin is for DAC.

Thanks

I2C DAC? SPI DAC? Parallel interface DAC?

Hi,

Could you tell me how to convert PWM to Analog if it is possible?

Thanks

Run it thru an RC lowpass filter.
Here's PWM, from 0-25-50-75-100-125-150-175-200-225-250 with 10K resistor and 4.7uF cap.
Or may 4.7K resistor and 10uF cap, I forget which.

You may want different values depending on what frequency response you want to achieve.
