This version of the active bridge contains the software code to use the adafruit "ads1115" 4channel 16bit adc add on application board. However to compile the listed Arduino code, uses will need to install the adfruit drivers from the url listed GitHub website as listed in the adafruit website page showing the ads1115 device.
Now at the present, I do not have a adafruit adc board, but I thought it fair to add the software modification to the sweep of code listed on my blog, so those how do have the appropriate ads1115 board, can at least use the list software below to obtain an "S meter" reading up to S9 + 44dB for their radio DIY projects.
This listing below includes some data measurement error traps, in that if the analogue port measurements equates to zero value, the calculation there after would not show an error in the mathematical calculations once the info is displayed on the 20ch*4line display. The display and the ADS1115 adc board both use the i2c network connection to the Arduino Uno processor.
All of the Arduino code variables are listed as global variables.
