@peekay123, thanks for the resources!
The SD Card stores recipes, firmware, and data. Information on the SD card then is either uploaded to or downloaded from a website, where recipes are made or data is visualized.
I only have UART available on my pcb for this feature, which is why I thought OpenLog was a good path to pursue. If I had SPI broken out, it would be great to jump on the SdCardLogHandlerRk, but that’s not an option currently. I’m investigating if @rickkas7’s SerialBufferRk can replace the SerialPort library in OpenLog.
