16  Using Arduino / Installation & Troubleshooting / Re: Arduino & EasyVR Connection Problem! (NEED HELP!) on: March 30, 2013, 01:02:25 am
Not sure yet.  I will break out my mega and hook it up this weekend.  What are you jumper settings on the EasyVR (HW, SW, PC, UL)?

Or...

Micro pin 8 (SS) to ATtiny Reset Pin
Micro pin 9 (SCK) to ATtiny SCK
Micro pin 10 (MOSI) to ATtiny MOSI
Micro pin 11 (MISO) to ATtiny MISO

Nice catch Coding Badly, I keep thinking of the mini when I see micro.

Here is a good tutorial for what you want:

19  Using Arduino / Installation & Troubleshooting / Re: Connecting a Arduino Mini R4 to an MiniUSB on: March 29, 2013, 01:09:45 am
Ah, I see.  I always thought I had a R4, but R5 it be...

Also, a note on the Reset pin on the MiniUSB (as I do not have one, but many other USB2TTL variants), I am referring to other users of the MiniUSB for the RTS use as a reset signal.  My other USB2TTL (FTDI232RL) breakout boards use DTR for the reset signal. I am unsure considering the "character" of sending Transmissions to Transmissions and Receives to Receives, but it will probably end up being DTR.

Anyhow, we shall see.

I am trying to exchange data via serial port between PC and arduino Leonardo. I know already that i must use Serial1 and not Serial because Serial is allocated for micro programming.

Try loading the 04.Communications "ASCIITable" sketch to the Leonardo and open the Serial Monitor at 9600.  Go back to the IDE and note that you are on Serial and not Serial1.

If you connect something TTL to D0/D1, you will need to use the Serial1 in your sketch.  You PC to Leonardo will be through Serial.

If you post you code, the "experts" will come   smiley

Code:
Don't forget to put the code in a "Code Block".

Did you upload the bridge sketch to the Arduino?
23  Using Arduino / Installation & Troubleshooting / Re: Connecting a Arduino Mini R4 to an MiniUSB on: March 28, 2013, 11:30:22 pm
Wow, that MiniUSB does have "character".

Okay, hook up the MiniUSB to the Arduino Mini GND, 5V, RX, and TX pin for pin (yes, TX -> TX, RX -> RX...).  For the auto-reset, you are going to need a 0.1uF ceramic capacitor going from the RTS on the MiniUSB to the R (Reset) on either side of the Arduino Mini.  If you do not have a 0.1uF on hand, you will have to manually reset when you upload the sketch and the "Binary Sketch Size" appears in the info window, press the reset button.

It is probably locked out, but the HV programmer should be able to unlock it and return it back to Factory 1 MHz.  Only 4 data lines, 5VDC, 12VDC and GND.  Just put the 1Ks between the ATtiny and your Micro.
25  Using Arduino / Installation & Troubleshooting / Re: Arduino Micro as ISP and atTiny84A on: March 28, 2013, 11:26:34 am
How about trying the Tiny core library?  It could save you the headache of reinventing the wheel:

Then you can use the Arduino IDE smiley-wink

In the command line, replace "-cstk500v1" with "-carduino".
27  Using Arduino / Installation & Troubleshooting / Re: avrdude: stk500_getsync(): not in sync: resp=0x00 on Sanguinololu on: March 27, 2013, 01:12:19 pm
The soldering looks good to me.  No bridges or cold solder joints to be seen.  Probably just the bootloader is corrupted.

I would suggest to give your Sanguinololu vendor a call or email.  Also, I would also consider picking up a programmer or an Arduino, could be a handy diagnostics tool in the future.

Of course there is risk of a electrostatic discharge (ESD) while soldering, especially when the weather is below freezing, and you will have no humidity.   Unless one takes precautions like a grounding strap and usage of anti-ESD tools, your electronic devices are susceptible to greater than 10kV events.

If you take a picture of the flip side of that board, I can see if I can visually see anything standing out in you solder job. 

Does the power LED seem dim to you?  I know it is one of those clear reds, so it has a smaller viewing angle (top view) and did not show up in the picture.  If so, you may have a short on your power circuit.  If you have a DVM, you could check the voltage across the LED solder joints (should be 4.5-5 VDC on USB).
29  Using Arduino / Programming Questions / Re: hitting SRAM limits? on: March 27, 2013, 12:32:31 am
Try this:
http://arduino.cc/forum/index.php/topic,118440.0.html

It is quite handy for the 168 and 328.  This IDE variant calculates the SRAM usage during the compile.

I have not tested the Atmega8.
30  Using Arduino / Installation & Troubleshooting / Re: Problem with communication Arduino UNO on win 7 on: March 26, 2013, 06:18:43 pm
That's annoying.  Have you tried to update the driver in the device manager?  If that does not work, I would un-install the Arduino and do a reboot to the PC.  This usually gets rid of any stupidity Windoze may have had before and you can re-install clean.
