BerryGPS-IMU compatibility

[mhgwilliams]

Hello,

I'm using the pisugar 2 with the raspberry pi zero w. I love the battery, super easy to get started and the form factor is really nice to use. However, I'm noticing some issue with my i2c devices when I use the battery. For whatever reason, when running 'i2cdetect -y 1' after installing both the pisugar 2 and the berrygps-imu hat, I get intermittent listing of devices. If I run that command over and over, sometimes I'll get correct listings, and other times the address where the device was is listed as empty. I checked my wiring and it doesn't seem to be the issue. when running via usb I don't get this issue. I double checked the addresses on the i2c bus aren't overlapping, so that doesn't seem to be the problem either.

BerryGPS-IMU for reference.

Am I missing something simple? not sure where this instability is coming from, would love a suggestion on how to troubleshoot if anyone else has similar issues.

Saw in issue #17 you requested specific addresses info dumped, so here's that preemptively.

pi@pizero:~ $ i2cdump -y 1 0x32

No size specified (using byte-data access) 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 10: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX etc, etc...

pi@pizero:~ $ i2cdump -y 1 0x75

No size specified (using byte-data access) 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 10: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX etc, etc...

Here is what I get with all devices connected using i2cdetect.

pi@pizero:~ $ i2cdetect -y 1

I have the same issue. Is there anything we can do to counteract that problem ?

Any progress so far ?

Hello! I have the same problem with PiSugar 2 Pro and a BME280 sensor. I do not get data from the BME sensor and also PiSugar doesn`t show information about charging and anything else. Some help to get both working independently? Thank you.

Some additional information:

It supposed that BME use the 0x76 address

While Pisugar and BME280 is connected I get this from the console:

When BME280 not connected, only PiSugar Connected:
