Hi,

Using the X1-demo board and a 877A chip. All I want to do is config portA so I can use the pins, An2, An4 An5 to read the voltage from and accelerometer. I started with the A2D8.bas demo code and all works to read pin An2, the problem happens when I try to config the A/D port config control bits from:

ANDCON1 = %1000 0010 ' An0-An4 configed for Analog Input

to

ANDCON1 = %1000 0000 ' An0-An7 configed for Analog Input

or

ANDCON1 = %1000 1001 ' An0-An5 configed for Analog Input

I'm only trying to read An2 but ,my display is not showing anything but sometimes flashes, any ideas?

oh, ADCON0 is:
ADCON0 = %11010001 ' Configure and turn on A/D Module


thanks

Seems simple, really just use
