Analog channel troubleshooting, RCM4000

Hello there, i have recently started to use the rcm4000 without the development kit. I use the digital I/O with “no problems” but at the time i intend to use de analog channel, Dynamic C don’t recognize the ADC.

What i did was this, i simply energize the rcm on the 3.3Vin and connect the ground and analog ground. All the other pins are floating (nothing connected to them) except for the analog input that i am using (it has the attenuator an capacitive filter).

I said with “no problems” because im also getting comunication problems, i can’t be running a program connected to the rcm4000 for more than 40 seconds aprox. This has to be part of the problem, but I think that at least should recognize de ADC.

Help… please…
