8x8 Led Dot Matrix Clock using PIC16F627A

Actually, I have made this long before the 5x7 led dot matrix clock. The clock utilizes a PIC16F627A and a 74HC595 to drive a small 8x8 Led Dot Matrix display (20x20mm). My dream is transforming these clocks to watches that I can ware on my wrist...

Setting Internal Oscillator for PIC16F627A

I love to use PIC16F627A and PIC16F628 because they come with internal oscillators. That means I can make a project with lower component count (without 1 crystal and 2 load capacitors). The project setting of MikroC for using internal oscillator of the PIC16F627A shows belo...

DS1307 + PIC16F877A

DS1307 is a popular Real Time Clock (RTC) chip from MAXIM . Now, PIC16F877A is my favorite microcontroller. So, I was looking for information about interfacing DS1307 with PIC16F877A but I found only information in assembly language (assembly is not my cup of tea) and other C compilers. I use only mikroC. I adapted what I have found from the Internet. The source code is listed below: //Sample code for //DS1307 RTC Ineterfacing with PIC16F877A //Coded by Pynn Pynn //Compiler: mikroC 8.0.0 //http://picnote.blogspot.com //07/06/2008 //Use with your own risk unsigned short read_ds1307(unsigned short address ); unsigned short sec; unsigned short minute; unsigned short hour; unsigned short day; unsigned short date; unsigned short...

Big 5x7 Led Dot Matrix Clock with new font

Now, I'm so crazy about led dot matrix clocks and led dot matrix watches. Just recently, I have upgraded my small 5x7 Led Dot Matrix Clock with a bigger green 5x7 led dot matrix display and a new font. For the images below, the time 21:44:37 was displaying on the clock. The clock display is big comparing to a 44mm Panerai (PAM 4). The code for the new font is showing below: const unsigned char char2[][4]={ {0x0E,0x11,0x0E,0x00}, //0{0x09,0x1F,0x01,0x00}, //1{0x13,0x15,0x09,0x00}, //2{0x11,0x15,0x0A,0x00}, //3{0x1C,0x04,0x0F,0x00}, //4{0x19,0x15,0x12,0x00}, //5{0x0E,0x15,0x12,0x00}, //6{0x13,0x14,0x18,0x00}, //7{0x0A,0x15,0x0A,0x00}, //8{0x09,0x15,0x0E,0x00}, //9{0x0A,0x04,0x0A,0x00}, //Comma1{0x04,0x0A,0x04,0x00} //Comma2};...
