I TRIED TO USE THE SD CARD NODE AND GET THE FOLLOWING ERROR:
How can it be solved?
Take a look at this post:
It raised an error, so it’s not a problem with the memory as in the mentioned topic.
Let’s look at the node description. It tells us that there may be a few possible errors:
fooba~1.txt. So, avoid using file names longer than 8 characters.
I hope it will help
Maybe frequency of writing to SD is to high?
I just finished a project that used the SD card log node. The key for me was making sure that the SD card board was connected to the SPI pins. The SPI pins on the Uno are 11,12 and 13. The SPI pins on the mega are 51, 52 and 53. I used 54 for the chip select pin on the mega and 10 for the Uno. I also used the SD card log node on an ethernet shield that had an SD card. It worked flawlessly. I wrestled with getting the SD card node to work for a long time, I feel your frustration. I can testify that the SD card node does work however.
If you want the clock to pulse every quarter second you need the RST on never not boot.
