INA219 issues

#1 Post by multilec » 14 Jun 2017, 11:52

Hi group,

A newbie here, my application is to measure the output voltage of 4 solar panels and display the panel readings on a small oled display in another location. I have managed to achieve all my objectives except entering more than one INA219 module.
I am trying to enter 4 INA219 units into a NodeMCU using ESPEasy.
The problem being that since the INA219 unit uses i2c for comms and has more than 20 addresses available, i cant enter more than one in the software since there is no field to enter an address,

Second issue is that when i do enter a second INA219 into devices the software lets me, but will not let me provide a name for it. My plan being to give it a different name and ID and use this to get more than one device.

Any ideas anyone?

Thanks in advance Nigel

Thanks Shardon,

This is helpful but it is not relevant to the build R120 im not getting any box to select the address. I will do some more fishing :)

Ok,

Version 2 seems to address the addressing issue, although i2c doesnt seem to work with more than one unit. Either way its working so im happy :)
