31  Using Arduino / Microcontrollers / Re: ATMega1284p new chip fuse selections in AVR Studio 4.13 on: February 17, 2013, 08:36:46 pm
I use to use ICE200 with the AT90S2313 and the AT90S8515. I purchased a JTAGICE from ebay and loved how it how it worked with AVR Studio. So will the 1284p work better with a resonator then I was reading over a thread you guys where working on using 16 Mhz crystals with Opiboot.

I was planning on using Optiboot with a 16 Mhz crystal. I've used JTAG with AVR Assembler projects I didn't know it was available to with Arduino.

Thanks I'll read that over I appreciate your replies Don

Before you load the bootloader don't I have to set fuses in the brand new ATMega1284p I got from Mouser.
All chip come running with internal oscillators correct?

I didn't see 16Mhz to pick from that is the crystal I plan to use with the 1284p. I saw 3.0 to 8.0 and at the bottom it had 8.0 I wasn't sure if that meant 8.0 Mhz and above. I could try to include a picture of the selection box..

Hi
I'm using AVR Studio 4.13 still and I was setting fuses for a brand new ATMega1284p chip.
Should I turn off JTAG operation? ISP has been enabled. Brownout is set for 2.7 volts
How large of a bootloader should I select? I selected 8.0Mhz -  crystal with the longest startup delay.
Will these setting work? Does anyone have a opinion on what I fuses I should select.
This is my first time setting fuses to use an AVR for Arduino use.
Thanks
Don

Do you need to capture pin state on the 8 channels? I have a logic analyzer but never use it to show glitch. Ive only use to to record pin state and debug the 68hc11 and 8048 8051 series mpu.

My dvr has an alarm input so I have a small relay that triggers it to record in high quality mode.

The 25% speed bump does seem worth all the new problems. Timer 0 is used for delays and the bootloader speed change too.

If you passed a pointer instead of a instance would you test to see if the pointer = NULL in the class member Begin()? before trying to use it. I'm trying to follow along here so get more experience.
I wonder of possible use myself.

Hi
Is there a Group of Arduino user or persons in Chicago that want to start a group?
I live near Midway Airport here in Chicago.

I appreciate your feedback, I will follow the convention as I move forward.
Thank you everyone who responded to the topic
I always learn something new with every topic I post in the forum. You all are respected!

Peter and Mark
Thanks I have a hard time coming up with simple solutions to my problems... I hope this gets better with time. Mark I understand that code in setup runs once but is there a reason why putting that for loop in Loop() is a bad idea? I want to learn do's and don't of Arduino. I've use the for loop in WinAvr.

Can you recommend books, or web sites to help learn the best approach solving the task needed?
I knew of modus arithmetic but wasn't sure how to use it.
