How do I initialize stand ram? I want to clear the standby ram (Version 6.0, 3068 bytes) to zeroes.
You can use
memset(ptr, 0, size)
Thank you ScruffR. I’m somewhat new to Particle Electron programming but it didn’t work for me.
Here is what I did:
memset(start_adr, 0, 3036) // where start_adr = 32
I received the following error: invalid conversion from ‘int’ to ‘void*’ [-fpermissive]
Am I not setting the start_adr correctly?
Thanks in advance
memset() needs a pointer to work on, but that’s not specific to Particle but standard C.
So you should write this instead
memset((void*)start_adr, 0, 3036);
But I doubt that the actual address of backup RAM is 32 - should rather acquire the base address from an existing
Another option to clear the area might be not to call
STARTUP(System.enableFeature(FEATURE_RETAINED_MEMORY)); after a reset, then reset again an then enable retained vars again.
