Nokia 1100 LCD and PIC Interface – The Best Combination That You Can Think About

Did you have an old Nokia 1100 cell phone that keeps lying in the drawer, but you just don’t know what to do about it? Well, guess what! Is time to show off your creativity by combine the Nokia 1100 LCD with the PIC Interface (Yeah, it sounds like a cool idea, isn’t it?). Before you starting the project, you have to make sure that your old Nokia 1100 LCD screen is in a good condition (Well, it would be better if the screen did not have any scratches). First thing first, please apply the Nokia 1100 LCD screen with a PIC, which well written in Microchip C on demand. As you can see, the microcontroller is a PCF8814 and its not the I2C. Although the chip us I2C capable, but the LCD doesn’t use that mode. In addition, the VDDI input can be used if only the I/O levels are different from the LCD supply voltage itself. The LCD supply voltage is 2.8V, even the VDDI id is in 1.8V. For this case, the LED driver as per the… Continue reading
