With JMRI 4.15.6, DCC++ (Arduino Uno and Pololu motor shield) hosted on PC running Linux the values reported by the track current meter (DCC++ => track current meter) are off by a factor of 100. For example a value of 512 reported by the DCC++ traffic monitor is shown as 00.5 % on the current meter; it should be 50.0%. I suspect the code divides the value by 1024 but does not multiply the result by 100 to convert to percent.
To verify this I modified the Arduino base station code to add two zeros to the current value (for example 51200 instead of 512). The JMRI track current meter then displayed the correct 50.0% value.
