DIY a PIC Controller Interface with Nokia 1100 LCD

Guys, no matter you believe or not, it’s a very obvious phenomenon that the mobile phone industry has been developed in leaps and boundaries, especially in the past few decades. As one of the largest mobile phone manufacturers, Nokia Corporation is always standing in the lead of mobile phone niche, as they’re launching at least 12 different types of new mobile phone averagely each year! Unlike other mobile phones, Nokia’s mobile phones have successfully setting its own brand, which most of the mobile phones have better and clearer LCDs. Due to this reason, the Nokia LCDs have always becoming a popular choice for hardware projects from the past to present days! Today, we’re trying to DIY a PIC Controller Interface with Nokia 1100 LCD. Why we choose the Nokia 1100 LCD? Well, it is because it’s the cheapest and easy to be interfaced with many programs. Basically, the controller that being used in this project is PCF1884 PCF8814, and it’s not I2C. Even though the chip is I2C capable, but this LCD doesn’t use that mode at all. The VDDI… Continue reading

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
