Hi,

if I understand this example correctly - in adcResultInMv_Vrefsh you get voltage reference high - which is connected to Channel 29. You don't need read this value - it is kind of feature for this example (you can setup breakpoint and check measured Voltage reference) - but not used for LEDs control.

Hope it helps.

Jiri
