@jpk Was there ever any response / resolution to this question regarding Fire
not really. But they put some more informations on the webpage. Which does not contribute to clarify things.
In the mean time there are a lot of modules and there is more and more documentation. But the documentation is really a bit annoying and not always clear...Questions in this forum are not really answered. Initially I really was impressed by the m5stack, but this lack of quality/documentation is a bit disappointing.
Want an example? Maybe you can sort it out (b.t.w it is still the same question of the first post in this thread):
1.) Revisions (new information on the page)
See this page, scroll down to "Version-Change"
But surprise, my PCB revision ("2018. 2A") is not even listed.. :-?
According the numbering scheme I own a PCB before "Initial public release" (or it is hex_2A=dec_42?)...?
2.) I2C Adresses used by the equipment
The "Fire is not explicetly listed here, but it should be part of "M5Core" section.
Again: Revisions (see 1.)) are not taken into account here.
==> Based on this information (0x68, see first post) I should have a MPU6886 (=latest 2019 PCB revision acc 1.)) installed...?
But this does not match the fact, that I have an old and undocumented PCB revision...
3.) As the "MPU9250 Basic Example Code" is working for me, I assume I have a MPU9250 installed, which again acc. 1.) would mean I have a PCB revision "2019.7".
4.) In the "official" (?) store
There is still written "9DOF: SH200Q+BMM150", even though the latest version should be "MPU6886" acc. 1.)
