I am developing a logging program. The Arduino is a Uno R2. It has an ATAfruit SD shield w/ RTC. For testing purposes I record data once per second. When I am finished testing I will be taking data much less frequently, although there might be random times when a few data points are only one second apart.
I convert the data ( a long; two strings, 3 ints) to a string in CSV format. But often not all the data gets assembled into the string. It seems that the += operation does not append the string to be added. I removed the references to the SD card and the failures went away, or so it seems. I need to run it for a longer time, but before I removed the SD stuff the problem showed up in two to four seconds. So let's assume that the issue was the SD writing. How might I go about exploring this issue? Thanks, -Denis _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
