Re: Elevator Model
if during "moving" you must perform something, then you should have one more state for moving. If not then just assign each floor one state, door_closed/open will be just signals which would be driven to correct value in each of the state according to the request.

PIC32 to FPGA
Thank you FvM! (but before PIC32 im going to drive signals from other pics, but i am going to supply not more than 3.3volts to them for that reason)
and the board is XUPV2P
DDR question
Your controller must also supplu DDR clock to your memory chip, and that should be an output from the DDR flip-flop which must be instantiated in your VHDL code.

Hello, im going to interface PIC32 to FPGA board which has some connecters which lead to its LVTTL pins...
as i saw LVTTL accepts up to 3.5volts right?
so i guess that wont be a problem to drive 3.3v signal as an input to FPGA with LVTTL pins?
Hello, i have placed PIC32 device on a board, added supporting elements, all capactirors...but when i tried to program it with PICkit2 ICSP pins it gave me error: VPP voltage level error...
then...i tried to check it, i applied just 3.3 volts to the chip and checked its every VDD pin...they all...
well i have placed PIC32MX360F512L device on a simple board...and added some capacitors to it...and tried to connect to PICKit2...and it says to me VPP voltage level error... however i did connect everything right... but only thing which is weird for me on this PDF schematic is u are using...
ok, thanks, i did find it... now the question is like that: With my hot air-gun i have a few rounded tips of different radius..
So, do i have to place PIC32 and point air gun with short radius tip along its pins around the chip OR should i choose a bigger radius tip and point it to the center...
i have the Hot-air soldering station now... i tried reinstall few chips... it was ok for practice... now im planning to install PIC32 on some board... but the thing is... i cant find what is the maximum allowable temperature for soldering TQFP100 PIC32 ? any ideas?
Ok im stil researching adn deciding about this...
and now, it seems to me that soldering with hot air gun would be actually easier! isnt it?
now...the thing is these hot air guns are pretty expencive, but i found some of these:
CSI899A+, CSI825A+
anyone knows anything about these hot air...
IanP...but people are doing it with 0.2mm as i see...how come? and there is no another package...and TQFP is not so bad... its just ME personally never did that... but many people succeed with this... that is why i want to know the soldering Iron they are using with 0.2mm tip...
oh one more...
pranam77: i never soldered TQFP chips (used to do regular soldering alot though), but even i notice that the video link u show is horrible... it is very bad technique and i wonder is that chip working after such a soldering.
FvM, thanks alot for reply, could you please tell me the exact...
ok which soldering iron would u guys recommend for TQFP soldering?
i saw many ones online...but kinda dont know whats better to choose?
take a look please at this tip... its 0.3mm

but the thing is i dont know to which...
Hello im going to use PIC32, with 100 pin TQFP package, pitch = 0.4mm
any tips on soldering such a chip?
i saw a lot of videos online..the one which i liked most of all was like that:
they put solder on the pins...melt it...and while melting move it along the pins...and solder melts directly...
vhdl code for32 bit processor
what you can do is to add final stage of D flip-flops, to make the registration of the output signals. that way you will get all your elements synchronized.
no need to force yourse ISE or anything... just add them in VHDL code of your design.
you can use the...
