Sending analog input to the microcontroller's analog-to-digital converter

Hi, I am trying to input analog data at port3 analog input pins (p3.2,p3.3,p3.4). When the program is run in the IDE it works fine taking all the analog inputs supplied through A/D converter peripheral...

ANALOG SIGNAL

I can used the analog/digital conversor with signals negatives and positive (e.g. signal sin) in the mM-509. This is have the register of 8051.

Problems with the communication with analog input module.

I am trying to communicate a microcontroller P89c51RD through serial port with a analog input(AI) module ICP_DAS. The AI has an own communication protocol, (send #011 and it responds to channel 1, i.e...
