Latching Relay vs Flip Flop
Hi,   Thanks for all your inputs.   I cannot go the latching switch route, because I have already cut the control board interface and fitted a standard on/off push...

Latching Relay vs Flip Flop
Hi,   This circuit will sit in between a 5V switch in a control board and an ecu module.  This circuit needs to remember its state on power down.   Circuit...

3.3V to 1.8V problems
Brian,   Yes I am dividing by two in CLKPR.  This works correctly at 3.3V.   Theusch,   BOD: I did see there is not a safe level for 1.8V, but I tried...

3.3V to 1.8V problems
Hi Brain,   I am using the internal oscillator.   So you think 4MHz, 9600 baud, 1.8v should be ok?   thanks.

3.3V to 1.8V problems
OK after double checking the chip, at some point it has moved from an ATmega324P to now using a ATmega324PA AU1522.   Yes I have tried changing the BOD levels but not luck....

3.3V to 1.8V problems
Hi Valusoft.   Well this could be my problem!!   What page did you find that on?   On page 2 of the datasheet (ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P )...
