136  Using Arduino / Project Guidance / Re: fastest pulse? on: November 06, 2011, 06:24:48 pm
Would this be better done with a 556?

137  Using Arduino / Project Guidance / fastest pulse? on: November 06, 2011, 06:12:58 pm
I need to produce 2 separate pulses, simultaneously, both pulses variable in both rep rate and pulse width. max frequency is about 1000 Hertz. Pulse width should be from 5% to 100%. What is the minimum time between 2 digital writes? I know I can time with milli's, but I am not sure what the timing is on writes themselves. I can't use PWM as rep rate never changes. I also unsure how I handle keeping width a constant % as rep rate changes. Is this possible with an Uno?

Due to other issues, I formatted the drive and reloaded Windows  again and reloaded the drivers. Everything worked! It must have been a bad Windows installation.

139  Using Arduino / Installation & Troubleshooting / is there a definition of terms for the preferences file on: October 21, 2011, 02:05:13 pm
I would like to set up the environment so it starts full screen with the last opened file opened. The terse keys in the preference file are not self explanatory enough to show me how to do this. Is it even possible?

Coding Badly asked some questions. I'll have the answers tomorrow if snow allows.

AARG!  I went to the site, went to VCP Drivers, downloaded "Installation Guides". They said unzip driver file to a location on your disk. I unziped them to my downloads directory  Then one step said" Select "Search for best drivers in these locations" and enter path "c:/cdm 2.02 02". There is no such directory! There was a directory in the downloads directory called  "CDM20814_CHQL_Certified" so I entered that. There were 2 inf files( ftdibus, ftdiport and I tried both with same result. When I got back to search window nothing was there.  Then I found these files are already installed in the Arduino directory. Tried those with same result.I could never get past this point.

Which Mega?  One with an 8u2 or FTDI chip?
The one with FTDI

I had a hard drive crash. Reloaded XP on new hd (500G-WOW), loaded Arduino 1.0. When I plug in the mega I got error from windows. It started the new hardware dialog. It could not find a driver for the board. Should not the driver be loaded with the Arduino Environment? If not, where do I find it. Google did not help! Before I was using Arduino 022, should I go back?

144  Development / Suggestions for the Arduino Project / Find and fix the stk500_getsync(): not in sync: resp=0x00 problem on: August 31, 2011, 08:50:12 pm
I see many posts where people have encountered this message

avrdude: stk500_getsync(): not in sync: resp=0x00
stk500_disable: protocol error, expect=0x14, resp=0x51

I am one! It seems the processor is bricked. I know is my case replacing the processor fixed the problem.

145  Using Arduino / Installation & Troubleshooting / Re: Will upgrade to optiboot solve the stk500_getsync(): not in sync problem? on: August 23, 2011, 11:29:45 am
I will keep one board for continuing to solve this.  Maybe i will install Optiboot and see what the differences are. Unfortunately the Mega is mounted deep within my project. I used the Duemilanove as a test bed for various modules. I need to move on right now to get things completed..


I am not sure my skill level is up to a remote control scope.

If rein0zn finds it difficult with 2 hands, he should try with one. I went through multiple tries but had no control over timing. The timing was totally random. I have given up. I ordered two Atmega 328 processors today. Hopefully this will solve my problem, but it is an inelegant solution. Looking over the older posts, this shows up regularly. Maybe it should be a sticky topic of it's own.

Sorry I was slow responding, I had to down to Denver yesterday.

I think I was fast enough hitting reset. The message was same as always:

Thank you too! I really appreciate the time you have put in on this!! My project is to automate the rolling roof of my observatory. I have trouble doing that now. I am slowly putting together the hardware. Arduino was perfect for my project because a Sensor board and some functional bricks allowed me to assemble it without soldering, somewhat hard with one hand.

It is an ATmaga328.
I only have one useable arm, so I jumpered reset to ground instead of pushing the switch. Interestingly the L light does not flash when reset goes to ground but does flash when reset is disconnected.
