Input from ports

Hi Raphael,

thanks for reply, well there is not BL2100 in my system. i m using RCM2300 Chip & ADC_MX_SERIES PCB Board. there is one AD Chip named TCL2543CN.



I thought you were using a BL2100 but no matter. In any case you must connect your analog signals to the analog connections. PD5 and PE1 are digital. You can not connect the analog signal to these. I am unfamiliar with the hardware you are using but this is basic electronics. Google the part number for the A/D convertor and see what you find.
