ADCIN does not work with AN16

[aerostar]

Anselc correctly set ?

[Alexey]

Yes,

ANSELC = %11000 'C.3, C.4 analog

C.3 and C.4 are AN15 and AN16

I suspect that unless there is my mistake somewhere, input # may be a byte variable in PBP3

I did the reading manually:


ADCON2 = %10000000 '111 'LEFT JUSTIFIED(0),not used,...
ADCON0 = %1000001 'AN16 USED 10000, NO GO NOW,STAY ON
ADCON1 = %1000 'VOLTAGE REFFERENCES
VREFCON0 = %10010000 'ENABLED, SET FOR 1.024 VOLT
RefNotReady:
IF VREFCON0.6 = 0 THEN GOTO RefNotReady

PAUSEUS 50
ADCON0 = %1000011 'GO NOW

ADCNotComplete:
IF ADCON0.1 = 1 THEN GOTO ADCNotComplete

AMB_TEMP.BYTE1 = ADRESH
AMB_TEMP.BYTE0 = ADRESL

VREFCON0 = 0 'DISABLE REFERENCE
ADCON1 = 0
ADCON0 = 0 'CONVERTER OFF, NO CURRENT

This seems to be working well

Which version of PBP are you using? The manual does not mention any limit to the number of addresses, but it is suspicious that 0-15 work and 16 and up do not...

[Alexey]

It is PBP3 3.0.7.4, must be the most recent. Actually I did not try higher #s than 16.
