Hiya Vasi, Eh mate I'm into the pic's and after I've spent some $$$ on prototype boards that were crap I now make my own. $76 seems alot of money for just 1 chip thats only costs a couple of dollars too. Glenn and a few other guy's here go for the picaxe as it's easy to program and the picaxe is basically the big brother to the basic stamp. If you like i can throw a heap of links to pic learning sites and tutorials to get you started. Nigel Goodwins winpicprog is a top site for learning with all his tutorials based on veroboard which he shows how to make also. The elmer tutorials are a top read too. Hope This Helps Cheers Bryan  |

Yes, thank you Bryan  , I want the links. I will buy only the chip. I looked around here and no picaxe but I can use that chip. Anyway, no rush because I already have a windmill controller with two A741 (with setup for car battery).

Hiya Vasi, Well mate here's a few links on the pic's Elmer 160 Tutorials Nigel's WinpicProg page and tutorials Microchips PDF tutorials Pete's World Lots of pic projects Peter Anderson's Pic page The Piclist Oshonsoft a Basic Compiler/Simulator for the pic Bill Bowden's Hobby page lots of good stuff there Gooligum tutorials very basic tutorials based on the 16c508/9 but a must read for beginners Olin Lapthrop's Embed Inc pic site (Advanced but some good stuff on there) Well guy's keep an eye on this post as I'm remembering more and more pic sites and adding them as I find them. My intention here is to make a link to the best pic related sites on the net so anyone can use it as a reference. Cheers Bryan  |

Bryan, the links are great! No need to bookmark each, only this page  . But the third link from bottom to top is not valid (but is only one - the rest are ok). Thank you!

Allo Vasi, Eh mate if you like I can post you a few pic chips or try or see whether you can get samples direct from microchip. I'm designing up a board for the 1687xa series that take a bootloader so you wont need a programmer everytime to re-program the chip. Let me know if you can't get samples as I'm happy to put a few pre-programmed bootloader chips in package and send them over to you. The 8 pin series of pic's chips are great but other chips with more pinouts are great as you can use a LCD as a de-bugging tool tool is a must and it only takes a few extra lines of code to see whats going on. I'm wrapped that I've got so far by just researching those links and learning so much and I'm sure once you get the bug it will stick with you. Cheers Bryan

Thank you Bryan, for start, I must buy pic12f675 for tests and learning (or maybe pic16f84). I never programmed microchips before, only PC for doing things on parallel port (but I am not afraid  ). It will take time for browsing your links and learning (but I want to do it).

Hello Bryan, I found this about bootloader http://weeklybuild.com/2007/01/07/microchip-pic16f87x-bootlo ader/ Hobbit name: Togo Toadfoot of Frogmorton Elvish name: Mablung Miriel Beyound Arduino Lang |

Hiya Vasi, Eh mate checkout Sparkfun and click on tutorials. Down the page is a bootloader called Bloader and screamer is the winblows software. Thats the bootloader i'm currently using with a 16f876a on a breadboard and its working perfect. The bloader is also good the 18 pin 18f88 and the 40 pin 16f877a so I recommend you try that one out. Cheers Bryan |

Eh Vasi, I have looked at the mikroe crap for a long time and after reading so many people having troubles and them not even bothering to respond to e-mails or the forum for poor guys who forked out heaps and either didnt get what they paid for or it wouldn't work. Personally I decided to get the ICD2 clone from sparkfun cheaper than their easypic boards and never looked back. One time silly me had pullup resistors to the pgc,pgd lines and blew 3 transistors on the icd, anyway I posted my problem on the sparkfun forum and within days the guys helped me out and I fixed it myself. Also bear in mind buy the time you buy the easypic4 and get it the easypic5 will come out and your expensive proto board you bought will be good to ripping parts off. If you cant afford to buy and ICD theres some circuits on the net that give you all the info on making your own. Cheers Bryan |

[quote] I investigated the use of ICD because EasyPic4 ICD do not let me use other compilers ... [/quote] I think this is the reason they don't sell EasyPIC3 anymore - to sell their compilers. Reading on mikroe forums about easypic3 and easypic4 problems is scarry but I think also users are guilty about malfunctioning. Anyway is a very nice motherboard (easypic4) for testing and experimenting with your uC. It has everything, keyboard, LCD's, ... I am sorry about problems ... I liked that board ... I want to build a windmill controller similar with piclog (picaxe 08M) but using PIC12F675 and in future, to build linistepper drivers for a little cnc router for pcb proto. Glenn, take a look to linistepper here. Hobbit name: Togo Toadfoot of Frogmorton Elvish name: Mablung Miriel Beyound Arduino Lang |

Thats a interresting link there Vasi. I recently updated my stepper drivers to microsteppers, at $99 per axis they were cheap but it still adds up. The Microsteppers made a big difference to the machines performance, almost double the speed. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |

I must add for readers of this topic that the updated Pickit1 is great for: [quote]PICkit Classic V1.74 supports these mid-range Flash PIC® microcontrollers: - PIC12F629, 635, 675, 683, - PIC16F630, 636, 676, - PIC16F684, 685, 687, 688, 689, 690, 785 - PIC16F913, 914, 916, 917, 946 Supported Operating Systems: o· Windows® 98 Second Edition o· Windows ME o· Windows 2000 o· Windows XP Other Requirements: o· Available USB Port[/quote] 
You don't get only a development board but also an USB programmer for those microcontrollers, documentation, a great (australian) C compiler (Hi-Tech), and a bunch of examples. Is the best way for learning how to program a raw microcontroller. Other ways can be painful. For Atmel ATmega microcontrollers fans (ATmega16, ATmega32, ATmega644P) I recommend this development board with a great of configurability: Pdf manual Is a Polish board and the good news is that you can use it with Microchip microcontrollers - not directly inserted (DON'T EVER DO THAT) but via those "one pin" connection wires (of course, you must remove the ATMEL microcontroller first). Someone is using it in this mode. And this way.
