Hi all,
I have noticed that none of the Silicon Chip MM2 projects use multiple IC2 devices.
Specifically, I would like to add the DS3231 RTC to an altimeter using a BMP180. In fact, I would like to have an RTC in any device both to keep the time and display the time on any Backpack when it's not doing anything else. This especially comes into focus with the Backpack V3, which provides a home for a DS3231 on the main PCB.
Is it possible to drive both the DS3231 and a sensor such as the BMP180? Does the native DS3231 support of the MM2 just hijack the I2C in such way that it cannot do anything else? Or is there perhaps some other limitation of the I2C implementation of the MM2?
I have no doubt that anything is possible by bit banging, but I am not competent to do that sort of thing. I'm looking for things that can be done straightforwardly using MMBASIC commands.
I would appreciate any clues you may be able to provide. I would not be all surprised if the answer is already on the Forum somewhere, but I have not been able to find it.
Maybe I am over-thinking it, and I should just add the DS3231 to my altimeter and see if it works?
Thankyou for reading this,
Lew.
