Further to my post. I have two modules working on an ESp32 but i need to get them working on a ESP8266. I know the libraries have been written with ESP32 in mind
I have got the code to compile for ESp8266 but when loaded it return only 255 or 65535 for the ADC values or i2c address
Can anyone advise on what changes to make to the libraries
Thanks

Thank you very much i begin to see how to coonect the modules connecting in active mode seems to work with the tester
Thanks again

Hello
I have two single channel AIN4-20ma units for a logging project. I am struggling to get them to work due to a combination of poor knowledge and documentation. I have the units connected to an ESP32 and I can see and read data from them but i do not know how to connect the 4-20ma signals. I have set the jumper to external 24V supply and have connected 24v to GND and 24V I only have a 4-20Ma tester and DFrobot 4-20Ma DAC all my attempts to connect these to the AIN4 give only a zero
I am sure it is me can anybody help with a simple circiut diagram for me to test
Couple of things i am running the module on 3.3V is that ok? and for the single channel unit the channel to use will be 0?
Thanks in advance

Hi
I have purchased two of the single channel 4-20ma input modules for a project which uses the ESp8266 processor. I have been able to compile the example for the ESP but when loaded it reports No Module. I can see the module at 55 with an i2c scanner but not control it
I have seen the issue raised on github about using other processors and have tried to modify the library with no success. I can load the module on an ESP32 board
Is there aproblem with using any other board except an ESp32?
Also does the module work with 3.3V instead on 5V
Thansk in advance
