My aim is to build a board with the following features<\/p>\n<p>a) All ports and  other on board devices must be easily taken out to a solderless bread board.<\/p>\n<p>b) In circuit serial programming.<\/p>\n<p>c) boot loader.<\/p>\n<p>d) the board will have some switches , an LCD module , a few LEDs  and  a pot for analog input simulation.<\/p>\n<p>My design is almost complete.  In fact, there is  nothing new  in the design. I have done  cut and paste from several circuits.<\/p>\n<p>I am planning to post schematics and experiences while building the board on this blog.<\/p>\n<p>Today, I have completed the in circuit serial programming module(ICSP). This is based on this <a href=\"http:\/\/www.diylife.com\/2008\/02\/15\/program-a-pic-microcontroller\/\" target=\"_blank\">article<\/a> by Ian Lesnet.My final prototype is shown below. The pcb layout for home brewing via  toner transfer method is <a href=\"..\/pdf\/jdm_pcb.pdf\">here.<\/a><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/images\/p1.jpg\" height=\"99\" width=\"112\" \/><img loading=\"lazy\" decoding=\"async\" src=\"\/images\/p2.jpg\" height=\"100\" width=\"112\" \/><img loading=\"lazy\" decoding=\"async\" src=\"\/images\/p3.jpg\" height=\"100\" width=\"112\" \/><img loading=\"lazy\" decoding=\"async\" src=\"\/images\/p4.jpg\" height=\"100\" width=\"112\" \/><img loading=\"lazy\" decoding=\"async\" src=\"\/images\/p5.jpg\" height=\"100\" width=\"112\" \/><\/p>\n<p>The original article uses a PCB mounted 9 pin D connector. I I found it inconvenient ,after soldering the board. Instead , Ifixed  a piece of ribbon cable. My programming set up is shown below. Just wire the connectors to the appropriate pins.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/images\/programmer.jpg\" alt=\"programmer\" align=\"middle\" height=\"100\" width=\"112\" \/><\/p>\n<p>The board lacks any indicators. I am planning to redesign the pcb with 2 indicator LEDs later.<\/p>\n<p>The software I used is <a href=\"http:\/\/www.winpic800.com\/index.php?lang=en\">winpic800<\/a> . It works like a charm.
