Merci pour vôtre réponse rapide. Je vais opter pour un ICD3 et puis une formation pour le début de l'an prochain aussi.

Je n'hesiterais pas à vous redemander vôs conseils.

Merci encore.

hello
i am designing a home automation system .
the system will be simple . it will just use a remote control to switch on and swich off  devices(maximum of 64) of a house.
it is first project of my life .
please guide me .
thanks i advance.

thank you very much.
i have doubt about which type of remote contol (RF or IR) should be used to give good value of money?
remote will have around 20  keys and should have range of 10 metres.

Hello,

I am helping a friend withthe dessign and development of a networked switch. This device is an on/off switch that can be controlled via the network. We are looking into making it wireless by integrating a WIFI interface. I saw Microchip's offering and see that ithas a Wifi Module that nicely integrates with a PIC uC; however, since this is our first interaction with MicroChip products, I am at a loss on how t proceed.

I am interested in geting samples for evaluation, but before I do this I need to determine what samples I need and what development kits I need to purchase. I know MicrChip has kits for PICs and the Wifi module, plus a TCP/IP stack. I just need orientation to determine what components I will be needing to be able to put together some sort of prototype. Can you help or orient me? Thanks, Salvador

Bonjour,

Je travaille actuellement avec un PIC32MX795F512L.

Ma question concerne la communication SPI : 4 modules SPI sont disponibles.

- Est-il possible d'utiliser un module SPI avec les 4 SS (Salve Select) ?

- Est-il possible d'utiliser deux modules SPI avec 2 SS chacuns ? Par exemple : SPI1 avec SS1-SS2 et SPI2 avec SS3-SS4. Quels sont les registres de configuration associés ?

Merci par avance

Hi, I`m not entirely sure where to start, but I have a reasonably old but Brand New! never used (until I had it a few weeks ago),  Microchip PICPAK II, 16C5x device programmer, dated Oct 26 1992, it has a PICPro II programmer in the box (and all the docs, chips, leads/adaptors and S/ware on 2 720k Floppies etc...)

I also have over 150 assorted 16c54s and 16c57s.

so Naturally I`m learning these 33 commands used and have already gotten the s/ware toolchain working propperly as well as the programmer (I use an old Win98 machine with DOS).

so all is GOOD! here

but there`s a snag, inside the device are 2x PIC16c57`s with the firmware to make the thing work, but these are JW chips (erasable)

that makes the data in their EPROM already 20 years old, this as you may be aware is about as far as eproms can reliably be trusted to maintain data integrity, so my aim is to Copy the firmware onto a OTP version, so the data will be there forever!

but I only have one device programmer/reader and it`s likely the Read Firmware fuses are set to make that impossible even if I could.

I have read on the microchip site that they even have one of these in their Museum! and as such have little to no data about them.

now I don`t know if you`re at all like me, but I think it would be a Terrible shame to let this device of mine become entirely useless simply because of time elapsed, and Not because of use.

so I need a favor please, can you dig out the Source code or even the hex code for these pair of EPROM PIC16C57s so that I can re-burn the data back on them and make them good for at least another 20 years!

(or more if I use the OTP versions).

I give you my Word as a Gentleman that I will not Share/Copy/or give this data to another soul, and will destroy it after I get these chips refreshed, you have my Word!

I`v brought back many "Vintage" computers this way in the past and enjoy doing it (and using them!), I seriously hope you share my enthusiasm in saving this machine, it`s really too nice to let it die.

All the best, and Thanks!

Thanks! and sometimes I wish I was the sort of person that Could just put it back in the box and forget about it, sadly in this instance I`m not. it really Does seem such a nice piece of kit and built the way I like stuff built, to let it just "Die" in a box, besides, I can`t really hold "Old age" against it

I will try and contact these people you suggest and keep my fingers crossed (unless it makes my typing Too sloppy!)

I`m also wondering after reading your reply if you can help me a little (not in This thread necessarily) with some 16c5x code?

I`m trying a small production run of HEX in, to a single 7 segment display/decoder, basically to replace/replicate the MC14495 chip.

I have the lookup tables already drawn out and each will need a RETLW op code for each line I believe.

I have no idea how to read port A (the 4 bit port) as I want to use them as the Input lines.

so in effect, read the 4 bit binary data on port A and then use that as the offset to read the 7 seg LED code to output on Port B.

it Sounds quite simple, but I can`t help but feel I`m missing OPcodes that I need (I program in Z80 machine code), how do I read port A as a whole for instance?

I realise I`m a little off topic here, so I apologise to the other readers here, and thank them for their patience.

All the best!

Hi YT2095,

As Mike mentionned Microchip has lots of application notes which you can find here : http://www.microchip.com/appnotes

Additionally there are a couple of very nice manuals with lots of tips & tricks for PIC micros. I was reading them myself back a few days ago because some of the tips are real good ;=)

you'll find them here :
