I need someone who could help me design a digital led clock with date with auto sync via rs485 from a pc or master..using a microcontroller. anyone interested please email me at alexdlsan@yahoo.com......thanks

[doyverine]

magandang araw sa inyo engineers again.....

tulungan niyo po ako sa Microcontroller/Microprocessor ko...

project po namin ay ROBOTIC ARM...

ma-simple circuit man na robotic arm o hindi try po namin gawin ^_^

pwede niyo bah mas-share ang link sa ROBOTIC ARM?

ito po account ko sa YM... obetdoie11@yahoo.com or post lang po dito na threads ang link sa ROBOTIC ARM....

maraming salamat po!

pagpalain kayo ni hesus!

just wondering po.. ano po ba ang pagkakaiba-iba ng hi-tech c, css c, proton c, mikroc when it comes to creating a program for pic?

just wondering po.. ano po ba ang pagkakaiba-iba ng hi-tech c, css c, proton c, mikroc when it comes to creating a program for pic?

Basically the expected outputs will be or should be the same.  The difference is how each compiler implements certain c instructions and pic specific  functions to achieve the common output.   Sometimes, automated or intrinsic instructions can be performed by one compiler but not by another.

Take the case for bank selection.  In both hitech c and ccsc, bank selection is automatically done by the compiler when accessing ram data stored in different banks.  This is transparent.  For the case of mikro c, for the pic 16 series, the compiler does not do this automatically, you have to manually set the bank select bits.

halu..

about this:

mikro c po kasi gamit ko for pic16.. uhm, hindi ko lang po sure pero sa iilang program po na nagawa ko, never ko pa po manually s-in-et yung bank select bits. though working naman po yung programs ko.. i wonder kung meron lang talagang versions na hindi pa automatic yung pagseselect ng bank.. i guess yung version na gamit ko, automatic na din..

MikroC can only access banks 0 and 1 automatically.  If your program uses 129 bytes or more of RAM, it will need to access banks 2 ( and bank 3).  This is the hassle with MikroC, you will get a warning regarding IRP bits (bank select bits) must be manually set.   Sometimes a lot of unknown variables specially the ones used by library functions will cause this warning if all the ram locations in bank 0 and bank 1 are used up.  Then you are forced to manually locate your own declared ram variables on bank 2 and bank 3 to make room for the ram used by the  library function which are automatically set to use banks 0 and banks 1 only.  This is the hassle in coding as each time you need to call your function or variables, you must manually set the IRP bank select bits.

I started learning on MikroC and when I encountered that limitation I switched to Hitech C.  In MikroC, you cannot directly compare ROM and RAM variables ... you have to manually copy rom variables into RAM and do a RAM to RAM comparison.

[simplymoody]

ooooh.. yun pala pagkakaiba hindi ko pa po kasi ako umaabot sa ganung scenario. thank you for the info.
happy new year

anu pong programmer ang pde s MikroC?? penge naman po ng circuit

now i know what you are saying sir. kakaexperience ko lang po nito. i was using hitech c before kaso my code is so messed up lalo na yung sa LCD part ko so i switched to mikroc for convenience. yun pala, mas pahihirapan pa ako. haay.

hi, gusto ko lang pong malaman kung anu po ba ung common language na ginagamit sa pagpoprogram ng microcontroller? dalawa lang po ung binigay sa min nung instructor nmin Assembly language & Visual basics.... thanks ..ECE student po ako 4th yr tinitake ko kasi ngaun ung Microprocessors..

[Macgyver]

pinaka common is C

Meron ng programmer at serial interfacing using TTL. Kaso lng walang PCB layout.
Sir taga Cebu ka ba?

Na experience ko din ito noong gumagami ako ng LCD using PIC887. Dami ako na i-save na mga phrases, na ubos na tuloy ang rom or ram sa bank 0 at lumabas na yung "IRP bits (bank select bits) must be manually set". Hanggang ngayun hindi ko alam ang solution. I am thinking to shift to Hitech C or Pic18 nalang.

thanks po sa mga info.

how to acces banks 2 and 3 using mikroc? ^_^ do i need to input some codes?

[RiDdLeR???]

Locate all your user ram variables to bank 2 and 3 using the "absolute" keyword because all the ram variables used by the libraries can only be automatically located in banks 0 & 1.

To switch to bank 2 & 3, set IRP bit to 1.  To return to bank 0 & 1, set IRP bit to 0.

thanks!    what is the major difference in mikroC ang mikroc PRO? which is better? is there some codes not applicable to the other?

[zrehtiek/keitherz]

code size limited ang hindi PRO
