It shouldn't matter (assuming the existing code works). ORing is the same as adding if the relevant bits start at zero anyway. I was replicating the existing code a "bit"

.

PHP Code:


			
void ReadTemperature(void) {...
    ADMUX &= (128+64+32+16);    // = 11110000.  So, this sets MUX to 0000, and leaves the top 4 bits unchanged.
    ADMUX++;        // This sets MUX to 0001, setting the A/D converter input to PIN 24, the temperature monitor.
...

void ReadThrottle(void) {...
    ADMUX &= (128+64+32+16);
...

void ReadCurrent(void) {...
    ADMUX &= (128+64+32+16);    // = 11110000.  So, this sets MUX to 0000, and leaves the top 4 bits unchanged.
    ADMUX+=2;        // This sets MUX to 0002, setting the A/D converter input to PIN 25, the current monitor
...
