Post by thread:[PIC]: Which Pic to use and how to program it

I have a old PicStartB. Could it peogram the 16F628 - 18 pin or 16F876 - 28 pin chips?

Where can I find more information on this? Yes. If you can live without an I/O pin, then my Trivial Low Voltage Programmer is one of the simplest to put together: http://www.finitesite.com/d3jsys I recently added an ICSP version for the 16F628 here: http://www.finitesite.com/d3jsys/proglvp-icsp.gif It works when the 16F628 is set for internal RC operation and MCLR as an input pin.

Michael, If you'll stick with 16F628 or even with 16F87X, then in some months you'll send postings "Is there any other PIC that is better to start with than the 16F628 or 16F87X". These guys will anser you: "No doubt: 18FXXX" So, why not to start with 18FXXX now? Look at our local retail prices: PIC16F628-20I/P 18LD 20MHZ 2K FLASH $2.74 PIC16F877-20I/P 40 LD 20MHZ 8K FLASH $6.00 PIC18F452-I/P 40 LD 40MHZ 16K FLASH $5.78 Do you see 16F87X line are obsolete for starting with? Do you see that for extra $2 for PIC18F452-I/P compared to PIC16F628-20I/P you get the ability to invest your time in things, you can use in future, not in garbage. When you finished your playing, 18F452 will be priced much closer to 16F628, even lower, may be. Good luck. Mike.

THERE DOESN'T SEEM TO BE ANYWHERE THAT YOU CAN BUY THE SILLY THINGS! And I actually did my homework by checking both Digikey and the Microchip online purchase website. You can't get one. It's also complicated by the fact that everything about programming the part vastly differs from programming the 16F family of parts. This includes algorithms, instructions, the number of bits sent, and others like having to do multiword, multipanel writes. It's going to require major upgrades to programming software and even some minor changes to programming hardware, such as the shift of PGM from pin RB3 on the 16F87X to RB5 on the 18F4XX parts. It's going to be a significant paradigm shift especially for the hobbyist. The best thing about the 16F628 is that it's more of the good thing that the 16F84 represented, literally a drop in replacement in the development environment, the programmer, and the target. While the 18F parts will fit in the socket that the 16F877 goes in, there's going to be a whole lot more work to do to get it to operate. How can I get some engineering samples? I need to start working on updating my TLVP and my version of the Linux picprg software to program these puppies. BAJ {Quote hidden}> > Good luck.

The 18F parts are finally becoming available and are reasonably priced. Some are priced less than the pin compatible 16F parts, especially in high volumes. This makes the 18F parts the first thing to look at for new production designs. The answer is less clear for learning and hobby use. There still is no 18F part smaller than 28 pins, which means there is nothing equivalent to the 16F628. However, the 16F parts have a big advantage for learning. There is waaaaay more stuff out there to help someone learn PICs with the 16 family. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: To leave the PICList RemoveMEpiclist-unsubscribe-requestEraseMEEraseMEmitvma.mit.edu

part 1 1185 bytes content-type:text/plain; (decoded 7bit) Hi Magnus and Byron, The prices are at http://www.microchip.com.ua in http://www.microchip.com.ua/sklad/price.zip However,I don't think they can sell abroad Ukraine. Usually I go to the nearest bank branch at the conner of the block, pay money (+2% banking charges +$1 for postal operation), then over day or two parts are at the center of my town (2km). What the heck is going in America? Where is free-market economy? Do not reply this questions, please, as Dale may kick anybody off the List for this. Regards. Mike. Ukraine.

It's just going slow that's all. I went back to Digikey and they now have nearly 2000 of the PIC18F452-I/P part. A bit pricey at $9.38 in singles, but at least they are available.
