Function Documentation

P3FromADC()

double P3FromADC

(

uint16_t

val

)

Converts a P3-Raw ADC Value to Voltage.

Note

The JTAGEN-Fuse has to be cleared to receive accurate values for P3 since the ADC4 (PORTF4) pin will source current while JTAG is enabled! The error may well exceed 15% FSR. This has to be done before the final calibration!
During debugging via JTAG, P3 is not measurable and Jumper X11 has to be disconnected for the voltage dividers not to interfere with the JTAG interface!

Parameters

val	The ADC Value

Returns

The Voltage
