I agree. It seems as though people on this list are bashing him and this product just because they might not find it useful. You know what? No ONE SINGLE board is going to make everyone happy! Just because it isn't catered to your needs and desires, doesn't make it a bad board. I've seen VERY few dev. boards out there for under $40. This supports alot, and has some decent specs. Just because he wanted to share this product, doesn't mean that you have to be so harsh and cut it down. Its a good board. Its cost effective. Its definately not a PROFESSIONAL LEVEL BOARD, but it is a good board for some that are learning how to program, like myself. just relax a little bit. Wouldn't you rather people on this list inform you of good deals and new products? rather than be left in the dark about it all?

If someone wants to start with uCPU and flash a led and control a motor from the first day, then he should buy a BS or a BX-24 module. You dont start with a PIC or AVR etc to "learn" another controller or to flash a led. Taking thing from the ground up is best for "how to get started" people. Afterwards its like learning to programme without any knowledge of C (the mother Language). All in all its the effort you want to give for yourself. |

Actually, I don't have any need for this board - I just wanted to see if there was a cheap product that answered the question "How do I get started?" So far I haven't seen a response for a cheaper way to get started! My own PIC projects are somewhat different: 2 ea MiniSumo Mark III's - I didn't do the electronics 2 ea Polulu robots that chase each other based on IR sensors - 16F876s 1 ea 4 level water alarm with local annunciation and output to autodialer for my sail boat - 16F628. Calls my home and cell phone if there is too much water in the bilge! 1 ea Control system for 15' battery powered launch with industrial joystick control, 2 DC drives and a linear actuator with feedback. - 16F876A 80C552 control for boat above with I2C LCD display of RPM, voltage, current with keypad input of security code plus keypad control of navigation and running lights. The horn is controlled from a button on the joystick. And, if you want to go way back - a TTL implementation of the IBM 1130 computer using fused link PROMs for microcode. This was the first computer I programmed back in 1970 and I built the system in 1973 because: I could and I have source for the entire operating system, assembler and Fortran compiler as well as the source for ECAP (the first electronic circuit analysis program). I never did get the disk drive done - I moved to the Altair 8800 in 1974. In other words, I don't need the development board - I just bought it to see if it would answer the question. I'm still waiting for a cheaper alternative! And Basic anything isn't it! --- In , "ydexter" <ydexter@y...> wrote: > --- In , "rtstofer" <rstofer@p...> wrote: > > > The point is this: can you find another example of a fully built > > development board, ready to accept code, ready to talk to a PC, KNOWN > > TO WORK, no soldering required, with ICSP (albeit LVP) for $27?

This is not a comment on the PIC 16f877 development board, though I
enjoyed reading all the comments on it. I'm an newbie at this. I've been fooling around mostly with 16c711s and 16f84s. I've haven't written a complete program as yet (been mostly modifing other programs to work on my project (stepper motors). I got tired of buying 711s OTP and got some 711 JWs and a eraser. My question is that it seems to take longer to erase a chip the more times I erase it, is this normal? And will my 711 programs work on 16f819 chips. Looking at the data sheet, they seemed somewhat alike. thanks bill davis ----- Original Message ----- From: "Vasile Surducan" <> To: <> Sent: Tuesday, June 17, 2003 1:46 AM Subject: Re: [piclist] PIC 16F877 Development Board > > Please alow me to comment a few aspects of this board functionality, > as you have described and I have seen: > On Tue, 17 Jun 2003, rtstofer wrote: > > > > > A while back there was a discussion on the best way to get started > > with PICs.

According to Microchip the 16F819 is upward compatible with the 16C7x devices - I'm not sure if that includes the '711. In any event both devices use the same instruction set so most of the code is directly compatible. The only exceptions might be with ports and internal devices. I assume you have a UV eraser - the lamp intensity falls off rather quickly when new so an increase in time would be normal. It should stabilize after 100 hours or so. I would move to the 16F819 as soon as possible! --- In , "Bill Davis" <wdavis@t...> wrote: > This is not a comment on the PIC 16f877 development board, though I enjoyed > reading all the comments on it.

Of course you have right ! In fact all our life is just a game. So I'm totaly agree with you, in case you wasn't sure. Be now. :) You forgot two important things. 1. A beginner must ( I'll use ** here but someone don't like those :) ) build with own hands the prototype. Else will never understood what electronics is. I have some experience, (not much but enough) with some students. 2. A good result in every thing you do is based on antagonical ideeas. An example is the democracy. So if I criticize a board which you are eulogize it, doesn't mean you haven't right or I havent right either. is just a game my friend, so play it nice ! top 10 wishes, Vasile http://surducan.netfirms.com On Tue, 17 Jun 2003, rtstofer wrote: > > Hey guys!

Based on this, I ordered a couple of these boards. Heck, that is only about $10 more than some bare prototyping boards I've seen, and just the 16F877 costs that much. Why would they put a 4MHz crystal on it? How have Futurlec treated you? IE, if you have a problem, how is their customer service? I ask because I ordered with 2 to 4 day shipping and tomorrow will have been 8 shipping days (discounting Sundays) since I ordered. I'm really disappointed as I was hoping this would save me some work on a current project.
