Bluepill - MAX44009 (GY-49 on Ali) lux sensor
Does anyone have a working sample of i2c with the lux sensor MAX44009? I'm trying with the one here for arduino https://github.com/RobTillaart/Arduino/tree/master/libraries/Max44009
and till now not getting anywhere. A few questions as well
- Blue pill pinout there are two SDA1, SCL1. I'm using PB8 and PB9 - I suppose it shouldn't matter which two I use. I've replaced the call as
- Lib above has default address for the slave as 0xCB whereas data sheet mentions only 0x9x range.. and diff addresses for reading/writing. what am I missing? I've replaced the ctor call with
Max44009 myLux(0x95);but that does not help either:(
- Thirdly, sketch seems to crash badly on the ctor call - looks like I'm in the bootloader. I thought my bluepill was a goner but blink works - so definitely something with the sketch.
Any pointers appreciated.
