Sorry I did not see your posting, I am on a PC
2  Using Arduino / Interfacing w/ Software on the Computer / Adding a new board on: July 28, 2014, 10:31:19 pm
Due to the fact that the ATMEGA32U4 is out of stock, I have to put together a couple of boards that run a small program that fits perfectly on the ATMEGA16U4.
I updated the avrdude.conf to include the definition for the ATMEGA16U4 and created the boards.txt using the leonardo entry as a base.
Every time I try to compile I get the error (unknown MCU 'atmega16u4' specified). Where else should I include the definition for the new MCU. Any help will be greatly appreciated here.
3  Using Arduino / Programming Questions / MEGA 1280 watchdog on: October 15, 2013, 12:11:44 pm
I have a solution that I program without the bootloader (using the ISP AVR MKII). I was having issues with a unstable network so I implemented a watchdog timer to reset the device if needed. The problem is that when it resets, it just stays reset, it does not reboots until I cycle the power. Can anyone point me in the right directions, as I stated, not bootleader programmed using [shift] program...

Happy to help...

I finally got it working, after reading a large number of postings. The issue is with the DTREnable and RTSEnable properties set to false, they need to be set to true, even though there is no handshake (HandShake: none), the virtual port requires this to trigger the data retrieval.
I hope this helps you as it helped me.

I am having exactly the same issue, no responses?
7  Using Arduino / Project Guidance / Actual MCU in Arduino NANO on: May 23, 2012, 08:21:50 am
Can anyone tell me what is the MCU on the Arduino NANO 3, is it an ATMEGA328p-au or an ATMEGA328-au?
8  Using Arduino / Programming Questions / Re: PWM @ 4MHz on: October 19, 2011, 05:09:08 pm
Thanks for your help, but if anyone needs to do it, this is the code I used to get a 4MHz at 50% duty cicle on pin 3:

pinMode(3, OUTPUT);
TCCR2A = 0x23;
TCCR2B = 0x09;
OCR2A = 3;
OCR2B = 1;

With this I get a very nice square wave that I am using as a clock signal for a smart card.

9  Using Arduino / Programming Questions / PWM @ 4MHz on: October 19, 2011, 12:19:32 pm
I hope someone can help me with this, I need to generate a 4MHz signal at 50% duty cicle using a PWM pin. It can be any of the PWM pins, can anyone help me with this. Thanks.
10  Using Arduino / Programming Questions / Wire.begin() already called on: March 09, 2011, 01:02:35 pm
Is there an easy way to know if the Wire.begin() has already been called?
I am creating a library and I want to call it only if it has not been done already.
