BM8563

[ririfonfon]

Good morning,
would it be possible to add the rtc BM8563 to your superb library.
indeed I developed a code with a ds3231 and I would like to change this one by M5Stamp-TimerPower
@https://github.com/m5stack/M5Stamp-TimerPower/tree/main
@https://github.com/m5stack/M5Stamp-TimerPower/blob/main/FacTest/M5_I2C_BM8563.h
@https://github.com/m5stack/M5Stamp-TimerPower/blob/main/FacTest/M5_I2C_BM8563.cpp
I found this, if it helps
@https://github.com/AdalbertSZ/BM8563/blob/main/BM8563.h
@https://github.com/AdalbertSZ/BM8563/blob/main/BM8563.cpp
THANKS

Where did you get your module? I just checked around and could not find a module that uses this chip.
Once I can get one, I can add support.

That seems to be a very specific designed power module that happens to include BM8563 for wake up ability. I can't test the BM8563 with that module as it doesn't expose all the pins.

I noticed a PCF8563, I wonder if they are clones of each other?

[Makuna]

After reviewing the spec sheets, they ARE clones of each other.

Something I noticed after reviewing the spec sheet, is that these do not have battery backup time unless they always run on a battery. They have no circuits to either charge or switch to a circuit supplied battery when the main power is removed. They either run on battery all the time or run on VCC all the time. This seems rather poor feature for a RTC where one of its benefits is once set they retain a running clock even when power is lost.

It's just something to keep in mind when choosing this RTC.

All the DS#### RTCs support this backup battery feature.

@ririfonfon I have a PCF8563 on order. I will have a branch with the support before it arrives if you would like to try it out. See https://github.com/Makuna/Rtc/tree/PCF8563. You can clone this into the same directory the library is already present on your machine and it will just work.

Great thank you.I'm dying to try this.Richard FontaineEnvoyé de mon iPadLe 23 juil. 2023 à 01:23, Michael Miller ***@***.***> a écrit : @ririfonfon I have a PCF8563 on order.

Let me know and I will publish the branch so you can give it a try. —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you were mentioned.Message ID: ***@***.***>
