How can I get the used and available RAM while running my program in a 20260?
GHIElectronics.TinyCLR.Native.Memory.ManagedMemory.FreeBytes shows quantities between 180,000 and 205,000
System.GC.GetTotalMemory(true) shows around 280,000.
I think those quantities are too low. (I understand the 20260 has a 32 MB RAM).
I’m asking this because my program kept hanging one minute after starting. I suspected that was caused by a lazy GC so I added a Thread that calls GC periodically. I started with a 10 secs interval, but had to lower it to 500 msec to avoid the hanging.
This is the output of GC:
