Multiple SparkX Power Meter - ACS37800 (Qwiic) on i2c bus with Datalogger IOT

Hi,

I am trying to use 2x SPX-17873 on Datalogger IOT. I changed the i2c address of one of the ACS37800 by pulling to 3V3 IO0 pin, but the datalogger only seems to detect one ACS37800 instead of the two connected.

Is this datalogger able to communicate with multiple ACS37800 ? It is running Version: 01.00.04 - build 0000bb

Thank you!

Hi Victor,

Sorry! I only defined one I2C address for the ACS37800 in the DataLogger driver. I think I must have forgotten that it supports multiple addresses… Or I was worried about address conflicts with other devices like the SCD30 and SCD40. (The driver already has to prove that it is not an MCP9600 or a VEML4040, before testing to see if it could be a ACS37800.)

I will investigate if supporting multiple addresses is feasible. I’ve opened an action here: https://github.com/sparkfun/SparkFun_Da … /issues/11

Apologies,

Paul

Hi Paul,

No problem, I will use only one per datalogger for now.

Kind regards,

Victor
