I can do it as uEEPROMLib, but then I would rather do it in a spare library as it can use too much resources.
It shouldn't be necessary to break it out into a separate library, it's just 2 small functions/overrides, I don't think it seriously threatens the "micro" nature of the lib ;) I've looked into it a bit more and I think I can probably figure it out, so I'll send you a PR when I get some time.
Problem is that using templates (on .h file, at end) can lead to a massive code explosion. Also, for paged reads you need at least 32 bytes buffer.
I'm literally just after something like int uRTCLib::ramRead(const uint8_t address, byte *buffer, uint8_t length); and similar for write. I don't see how that would cause a code explosion. I don't care about supporting read/write of arbitrary types; this is just about reading/writing a series of bytes all at once with less I2C overhead than doing one at a time. These RTCs supports reading or writing an arbitrary number of consecutive bytes, so I don't know why a 32-byte buffer would be needed?
Hi First of all thanks for this library, and for so promptly incorporating my earlier PRs. This time around I have a suggestion but don't have a PR because I'm not sure how best to do it. In Adafruit RTCLib there are functions to read and write an arbitrary number of consecutive bytes from/to the RTC's SRAM into a buffer in one go. In fact the 1-byte read and write just call these functions with number of bytes = 1. It would be great to have this in uRTCLib too. I am currently working around it by reading one byte at a time, but that obviously comes with additional I2C overhead which it would be good to avoid. Cheers Ben
