Hey guys,
I would like to run an SD card logger through SPI on a AVR mega.
I think the processor has better availability for PCB projects and I started looking at this like 2 years ago.
I pulled the latest master software and was pleased that Josh implemented a lot of work on this front. However when I add the SD logging files I instantly exceed the SRAM limits.
Do you guys have any tips for me how I could save some big chunks of global variables or is there a branch ongoing working on this topic?
The engine is really simple, not sure if there are some advanced functions I could comment out.
Sorry, haven´t spend much time in the project yet, so I would really appreciate if someone could point me in the right direction.
Thanks
Andre
