Possible mixing ADS1115 #1 with #2?

[Merga189]

Hi Michel.

There were some questions about using ADS115 in the German forum, so I had a closer look at it.

One thing I noticed.

Connecting one ADS1115 to an UNO and running a I2C sketch I get ADS1115 with ADDR open or GND >> 0x48, with Vcc on ADDR 0x49 which is OK.

In your config.h versions I see

#define I2C_ADS_Add1 0x48 // I2C address of ads1115 when addr pin is connected to ground
#define I2C_ADS_Add2 0x49 // I2C address of ads1115 when addr pin is connected to vdd

But connecting the ADS1115 to RP2040 I get in terminal output

with 0x48 >> 'Second analog to digital sensor is detected using ads1115'

and with 0x49 >> 'First analog to digital sensor is detected using ads1115'.

Seems to be a little mixed up or am I wrong?
