can someone please let me know where i can find the GRIDS Bootloader file…please, I have the Grids.hex file
I don’t know for certain, but since it’s ATmega328 based, it’s quite possible it doesn’t have one.
The arduino environment uses one, but I gather that’s not how it was done - and those chips can be programmed without one.
I looked up the link I have, which is here:
https://www.muffwiggler.com/forum/viewtopic.php?t=142320&start=100 (at the top of that page, there’s a link to the whole collection)
but there’s just the .hex and .elf files for the Grids firmware - no bootloader.
If you ask there, you may well get a reply from the guy how posted all of those.
Thanks for trying…
