I have a few prototype projects involving an ATMega328P and have been using it due to its simplicity and compatibility with Arduino, and I seem to understand the basics of the code alright after working with it for a little. I keep running into the issue where I run out of flash memory to store my code, etc, and in some scenarios I am also running a few I/O pins short of what I'd like to see. Are there any other processors with bigger memory and more I/O pins that the Arduino Bootloader can be uploaded onto? How does this work as I am unfamiliar.
If there is a particular suggestion in terms of solving these two issues without having to drastically change the software it would be excellent. Thanks for any insight ahead of time.
That actually sounds quite good if they make it in a through hole package, do you know if they do? I cannot seem to find it and as this is a prototype. I did see a few breakoutboards, which I could consider, but it is already a pretty pricey chip (in comparison with the 328).
If there are any other more cost effective solutions it would be great. Thank you.
Additionally, do you have any tips/assistance as far as burning the bootloader (I dont have an MKII yet and haven't been able to get it to work with the barebones arduino method even on the 328P's I have without he preburned bootloader) ? Thanks so much for the help.
Excellent - this is the first one I can get to upload the sketch without errors, however when I try to burn the bootloader I get this error avrdude: stk500_getsync(): not in sync: resp=0x00 I am pretty sure my simple circuit with the 328P is set up correctly (I dont have the RBB PCB like Gammon does, but I had it built on a breadboard before so I have been using that.
Any suggestions as to what theis error means or how to solve it? Thanks so much this looks like it is the right route if I can resolve this issue, thanks again!
OH! I figured it out, That error comes up regardless, but I can still bring up the Serial after and Burn the bootloader. I am having some issues with my Atmel Studio and also having trouble changing the fonts using the theme.txt modifications as said in this forum, do you happen to have an IDE/solution that you would like to recommend? I am going to get some 1284's shortly here, but it will probably be a little while before I actually get the chips in and get something uploading on them so I look forward to doing so. Thanks for the help, I really appreciate it.
My 1284P kits & boards are still available, with onboard FTDI module available as pictured, or offboard FTDI Basic may be plugged onto header pins instead. http://www.crossroadsfencing.com/BobuinoRev17/
