Re: Using the onboard RTC on MAX32

Yes, it would require some major reworking of the board to use the built-in RTCC. Not something I'd want to have a go at. You'd be much better off using an off-board RTC like the DS1306 ( http://www.maxim-ic.com/datasheet/index.mvp/id/2687 ) which communicates through SPI. I guess the onboard one ma...

I haven't followed any "standards" as regards the interface to my library. Maybe the two could merge one day...? Who knows...?

Re: Using the onboard RTC on MAX32

The oscillator would need to connect between pins 73 and 74 on the microcontroller.

The Max32 doesn't have provision to connect these pins to a crystal as they are in use as part of the IOL connector J14.

Real-Time Clock Library

I have created a Real-Time Clock library for the Uno32. It's in beta at the moment, so please try it out and see what breaks. It supports all the functions of the RTCC module, including alarm interrupt, output pin control, etc. You will need to add a 32,768Hz crystal to the X2 footprint to the top-l...
