new extended range PIC 16f1824
This is a new product line introduced recently.
It is based on 16F instruction set. -Can read FLASH memory via FSR -Two FSR registers, 16bit -Linear RAM area (remapped) -256 bytes RAM, 4K FLASH -Internal Osc. 32 Khz-32 MHz -Branching instructions -Interrupt context saving and much more! It is better and easier to use than the older 16F models. Indeed I do not use them much anymore! It costs about 1 dollar and I highly recommend it. On the web there are pages where the 16F84 is used but this model is stone-age so to say! I made a small PCB including DC/DC converter for 1.2 volts (using the new MCP1640 chip). The assembly is totally difficult, I do not really want to build and sell them. If you do not need the DC/DC chip, it's rather easy to do it, and I could set a price of 5 dollars. This is NOT an advert, as I do not make a living out of this business. Selling things on eBay is more like a hobby for me! Here the URL: http://pic.mtfuijitown.info There are more PIC topics and the 16f1824 information can be found on it's own sub-page. 16f1824 battery powered by yakone syndrome, on Flickr This PIC needs at least PICKIT3, and the latest MPLAB install. |

my site address has changed:
http://pic.hitechworld.org wiki was installed: http://hitechworld.org Here you see one prototype I built a few days ago. http://www.youtube.com/watch?v=BS8MEXvWjDE 5x5 LED matrix, 16f1824, 74hc595 anodes drive, fdv301N digital MOSFET kathodes sink. MCP1640 dc/dc converter- works from 1.2v NiMH battery. Scrolling message algorithm was programmed. To modularize it (RISC assembly), and to use proportional font, the complete scroll is at first built inside the internal RAM, and then read-out column-by-column. 1 byte= 1 column, only 5 bits are used. Modularized means the bitmap generation from font, and the scrolling itself are completely independent. bright LEDs by a good days work, on Flickr |
