you welcome

hi again i was working with my friend on project using 16f886 when we set ADC external Vref+ ..the adc not work he looked at the file PIC_CAL_ADC.c and changed "if (Vref != 0) st_bit(adcon0, VCFG0); " to "if (Vref != 0) st_bit(adcon1, VCFG1);" and the Vref+ worked fine he have flowcode v5 ..i think ...

thanks alot

hi all

i am using 16f88 internal RC 4MHZ (in the main"osccon=0x60;//4MHZ")

when i test the program on Proteus i found that my delay 5ms become 9ms !

is it normal for internal RC?

thanks

ok thanks alot Benj

hi
if i want to disconnect DP pin..i will connect DP to ground directly ..how can i do that?

thanks

hii

how do that in flowcode? could you give me the code?

hi i have pic16f88 ..when try simple program for test the delay get bigger...i mean before the led start there are 300 msec delay in real life the delay become 3 second! i thought the problem from the pic so i bought 3 more from other shop and same problem i have pickit2 clone and it work fine for a...

hi
i have flowcode 5 free ...i need to make delay (us) ... 500us and 1500us and 2000us ...to 11000us

the delay don't accept any number above 999....any c code for this problem???

the pulse length 500ms...i want highest resolution..1us or ns

hi Benj
i want Measure pulse period..any suggestion?

hi
i am using flowcode 5 free version and 16f627a with 20 MHz crystal.....i want use TMR2 to make 1Mhz interrupt per second...i couldn't make it....it give me about 45000 interrupt per second...why?

thanks all....you helped me alot

hi i have pic 16f627a with 4 MHZ internal ....what is the best way to make square wave(0v..5v) with the maximum frequency? i am now working with this : loop...> (output B0 = 1...>output B0=0) . without delay. what is the output frequency will be with that? any other idea to make very high speed freq...

hi i am trying to make frequency counter..the program will count how many pulse in specific time using TMR0 then save it to variable(count1)...then repeat the operation and save to (count2) then if count1<>count2 output B1 pin..then loop..atc when simulating with proteus it don't work...and in the r...

hi
any one help me..i want make program to calculate the pulse length...any example will be good

hi all i am using pic16f627a for my project...the project include ne555 generating 10 khz and the pic will make some maths..the problem is that the micro controller work fine until i connect the power to ne555..every thing go crazy..all buzzers beeping! so i am using Breadboard and on it{16f627,ne55...

thanks medelec35 ....good solution

hi
how make loop for specific time? i am using pic 16f627 with 4MHZ

thanks
