Thanks, but I'm a little confused as there is a base-emitter diode drop between VO and VEE of the PNP transistor (about 0.65V) in the temperature compensation circuits. Also VDD-VO is specified as ...

Anyone?

According to the ST7032 the absolute max input voltage Vin is VDD+0.3V which means the controller has substrate diodes and is not 5V tolerant, the controller cannot take interface signals from 2.7V...

According to the ST7032 spec the SDA and SCL lines are on DB7 and DB6 respectively. These have a Vol spec of 0.8V with Iol of 1mA (quoted at 25deg C), so that's an equivalent resistance of 3k3 at 3...

OK, if I understand you correctly you want the LCD to 'snoop' on the serial stream and be completely agnostic to the sync protocol. Presumably this means the packets that you send contain a start a...

Can you determine in the stream whether the data is meant to be displayed or not? the ST7066 controller has an extended 80*8 DDRAM area and says you can use an area of DDRAM not used for display to...
