Iam doing a project for datalogging of some AC and DC parameters.
Using RS-232 comm.
MCP506(multiplexer) gives the multiplexed o/p to RMS-DC converter and then to A/D converter, and the corresponding count is displayed on pc.
But the settling time of rms to dc converter is more , because of which there are error in ac signal reading.
How can i rectify this problem.
Microcontroller used is AT89c52.
serial port communication is polling based.
if i increase the delay between reading of two signals, whether this will help, and whether this wld effect the rate for comm.
Plz help
