Hi bob, I am using battery power supply in measuring part (4x AA), for AVDD i am using +2,5V and for AVSS -2,5V, for DVDD i am using +2,5V and for DGND 0V, this way I am avoiding disturbance from digital part. The reset pin is direct connected to DVDD (pulled high +2,5V) so I guess the links are fine. Waiting time is not problem for me because I am sending commands true "coolterminal" com port and my waiting time is more than 2sec. I try to send command as "0x55 RESET" and "0x55 START/SYN" but there was no respond from ads. Only "RESET" and "START/SYN" commands without 0x55 sending back "dots (now word)". I also try to send "RREG", "RDATA" and "0x55 RREG", "0x55 RDATA" commands but there was no respond on any of these command. How can I now if there is data to be returned or there is no data to be returned ?, do i need to set registers before reading commands ? Best regards, Matej
