Technical support / ADC voltage
« on: November 21, 2006, 06:41:46 AM »
I recently bought a T100MD-888+ PLC,
I put a pot across the Analogue supply and read the ADC(1) input to an LCD, between 1.2 and 5 Volts I get 1000 to 4092, anywhere below 1.2v The values roll over to 9960 and then drop off drastically before rolling over once more at 0v, is this normal? And if so, is there any way to set the range of the ADC's for 0 to 5 v input?
Thanks
