Oh, yeah, you need a 2nd 100nF cap, for AVCC. You only have 1 on Vcc.

 

Can anyone point me in the right direction with this?

Hopefully this post helps others avoid wasting time debugging an "error" that's not necessarily their own.

I don't know how helpful it will be considering you yourself missed the many other posts about this same bug.

I have my ATMega1284p on a bread board presently so I was thinking of using male/female jumpers I have to connect my ethershield up and if it works purchasing a w5100 standalone module to use.

I have been fighting this for months and finally found MY problem: ESET Smart Security  was apparently constantly checking USB ports and the Virtual com port etc.

My solution:

ESET Smart Security
 - Realtime File system protection
  - Advanced Setup
    - Additonal Threatsense Parameters..
    

• Advanced heuristics on executable files from removeable media

[exceptions]
          (Mark ALL USB PORTS AND CONTROLLERS)

IDE 1.04 and 1.05 BLINK went from 2 minutes to 15 seconds to Verify!  (FIRST Verify can take a long time.. 60 seconds or so...)

Just one example of weird interactions!

if I use shift register? I can control 20 servo without noticiable slowdowns?

I build a robot (the blue is servo)

basic is: 20 servos, arduino uno, gyroscope

100000 is too big to be held in a 16-bit signed int. Make pitch an unsigned long and that might work better.

Also, pitch<=10 would make more sense if it was pitch>=10.

Also, pitch is not a good name since this is really the half-period, which is more like the inverse of the pitch.

You have defined a global variable named pitch and also a local variable of the same name. The global variable is not used; you could get rid of it.

Since you have defined a variable piezo to record the pin number, it would make sense to use that in the call to pinMode() rather than duplicate the value. For extra brownie points, make piezo a const.

Hello
I found in ... \ Arduino \ hardware \ arduino \ bootloaders \ atmega \ ATmegaBOOT_168.c these microcontrollers:
AVR_ATmega128
AVR_ATmega64
AVR_ATmega32
AVR_ATmega1
AVR_ATmega8
AVR_ATmega88
AVR_ATmega168
AVR_ATmega162
AVR_ATmega163
AVR_ATmega169
AVR_ATmega8515
AVR_ATmega8535

Now I want to know, if all the specified MCU are compatible, to load the Bootloader on these MCUs, from my ARDUINO UNO. Whether are there other compatible and witch board i have to choose in AIDE to upload the bootloader for each.

I've downloaded the Arduino APP at least a dozen times and every time OSX says that it's corrupt. So... I downloaded the Arduino source from Github with the intention of using the Apple App developer to compile it. But... I had to download XCode from Apple... and now I'm stuck. I can't figure out how to create the Arduino.app so I can start learning more about the Arduino.

Code:

This was from another forum...
However the issue is I Based on the USB host documentation, it sounds like you may have a conflict on pins 11 & 12.

Digital I/O pins 8-13. In this group, the shield in its default configuration uses pins 9 and 10 for INT and SS interface signals. However, standard-sized Arduino boards, such as Duemilanove and UNO have SPI signals routed to pins 11-13 in addition to ICSP connector, therefore shields using pins 11-13 combined with standard-sized Arduinos will interfere with SPI. INT and SS signals can be re-assigned to other pins (see below); SPI signals can not.

I need advice and am willing to provide anything needed.
