Hi there..
anyone may can help me fix this.
I have one stuff the LCD display damaged and cant be fit new one ,because no more in the market.. And now i have and idea to used 7 Segment LED connect to the MCU..
Because it have signal from MCU S0-S32 and COM0-COM2 and NC connect direct to the LCD.
the circuit used uPD7514 and have LCD segment driver inside MCU.
Now i have removed the LCD and check the line inside of the LCD.. now i know the PIN where they come from MCU and go to LCD ( pin ) each pin.
But how I can covert this signal from S0-S32 to the new 7segment LED ?
Because i think if used connect direct from this out to 7segment LED it will not work ?
Because i saw that " sample "
the signal from ie S1 go to the pin of LCD through " symbol " the liquid line on display and go through to the com line and the circuit go back to MCU.
I dont know will have some IC to convert OUTPUT from MCU to drive 7segment ? and how about com line ? because all com line will go back to the MCU.
If i used small 7 segment connect direct it will work ?
anyone can help me about this
