Hi all, I have problem in converting 26 bit binary to bcd using PIC 16F782 using assembly language. I need to convert eg 2FAF080 hex to 50 000 000 dec using 4 registers casade together.. which mean 4 bytes. actually my application is to make use of timer0 as a counter to count the input freqency and store them in a 4 byte register.. (...)
I searched in internet and find code for converting 8 bit and 10 bit numbers So you got the answer, isn't it? I presume you know how to delete lines of code.
Using Couleur's Technique (BIDEC), a binary number (most significant bit, MSB) first is shifted and processed, such that the bcd equivalent is obtained when the last binary bit is clocked into the register. The basic rule is: if a 4 or less is in a decade, shift with the next clock pulse; if 5 or greater (...)
8 bit or 16 bit? here is an 8 bit routine: ;***************************************************** ;* "bin2bcd8" - 8-bit binary to bcd conversion ;* This subroutine converts an 8-bit number (temp) to a 2-digit ;* i.e 0x15 becomes 0x21 ;* result in (...)
can anyone share me code that converts an 8-bit binary to bcd. im using the Altera Quarus II compiler and programming into the Altera DE2 board. my intention is to convert output of a counter (8-bits) into bcd and then display it on the 7-segment. both the counter and bcd-to-7 segment (...)
Hey guys, I'm using a pic16F690 and I need assembly code for to convert an 8 bit binary to bcd and bcd to binary. I have to use the w register. Also, I only want to display numbers from 0 - 99, how do I write a default or error message in mplab? Thanks for the help :) Check there are tons of code of th
Hi Alexander, I think that convertin a 24bit binary number into bcd format is similar to 8bit BIN2bcd. char i; // counter char binary; // binary number char bcd; // bcd number for (i=0; i < 3; i++) { bcd = (...)

i want to know how to convert binary to bcd or decimal in assembly i want a code thanks you can use simble method for converting 8 bit binary number into decimal equivelt stored in 3 memory locations code for 8051 family( let r0 contain the binary number and r1,r2,r3 contain decimal equavelent) (...)
Hey Everyone! I found a routine on the web that converts 10 bit binary to 4 digit bcd But I think there is a typo because there is a goto b2d2 and the b2d2 isnt listed on the code...... Anyone have an idea where the b2d2 should go???? Any other 10bit to 4 digit bcd routines???? I'm trying to display voltage (...)
Try this, or browse code on same site. ;)
you should be able to do the transformation by first doing a mapping. Use the truth tables and the graphical method for each output bit. Many years ago there were commercial ICs for this. Try looking through an old TTL data book. They will have diagrams of the logic inside the chips. 74185 is one example. The 74185 turns ou
This question has really got me stumped. Consider a ROM eith 7 address(input) lines and 8 data (output) lines. How many bits fro the ROM need to be used to implement a binary to two-digit bcd converter? The answer is 800bits. All I can think of is the capcity of the ROM is 2^7 x 8 = 1024 bits, so (...)
How to display 16 bit binary number on Seven Segment....? without using mcu u can use bcd convertor i.e binary to decimal ic like7447 and 7448 .
I have searched the forum but couldn't find what i wanted exactly.. Say i have an output from an 8-bit binary counter "95" .. I want to display it on 7-segment displays on a spartan 3E FPGA board.. What is the solution of this problem even if i got the bcd conversion, how can I display it on 7-segments? Thanks for your concern..

Hi there. I haven't the foggiest on the best way to do this in ASM. What I need is to convert a hex number to the hex representation of the decimal number. For example: Start with: 2Eh (It iss equal to 46d) End with: 46h I need to end up with the byte in hex because of how I send the byte to the screen by converting each nibble into i
OK not a BIG deal u can use Micrcontroller in between 8-bit parallel data & three 7-segments display, just u need to program the microcontroller thatz it . . .

mmmm... how many digits do you need? alas, how many bytes is your number stored? don't forget, that the microcontrollers has all it's data in binary form, it could be 8 bit integer number, 16 bit integer number, 32 bits integer, or even 32 bit float number.... (too many)
Hi vveerendra Here is my understanding about what you've wrote , tell me if it is correct : you want display a decimal number on seven segment but your number is binary and you need to convert it into decimal right ? If my consideration is right you can go through many of the available binary to 7 segment integrated circ
In your previous post you mentioned GAL16V8. Do you still have to use it? Its application can be conversion from input buttons 1, 2, 3,...9 to their 7-segment codes and then using modulo-7 counter shift them into 28-bit shift register and display this 28-bit register as 4 x 7-segmant. Can you use a small microcontroller? Would be quite easy t
8051 bit MASKING: I have to use same PORT (SAY P1) for bcd to 7-Segments and other for four different Switches. My Question is: How to mask bitS/PINS which does not cause any effect to other pins when i have to acces PORT for bcd to 7 -Segment Decoder. Please Clear me concept of bit Masking (...)
Hello everybody. I wanted to use a 27c256 EPROM as a binary to bcd converter. Basically the 16 bit binar number is the address while a 8 bit bcd in the output. Simple enough. But I don't know how to produce a bin or hex file which would load the wanted data in the EPROM. Please note that this is a part (...)
Hello, I am doing project with 8051 "Simple calculator" I done addition but I have serious problems with subtraction. I’m using LCD and keypad. Math functions must be with 2 digits _ _ - _ _ = _ _ For example I write 20 - 1 and I get 1Fh (dec 31d). :idea: So I need to enter numbers save them in R1 and R2 and then convert int
I suppose you meant ADC's output! Indeed it is not trivial, specifically when converting the 8-bit binary to 10-bit bcd! But converting the 10-bit bcd to 7-segment is easy, using for example IC-4511 or 7447! A Truth table is one way, perhaps on a PROM! also see

The '163, 'LS163A, and 'HC163 are 4-bit binary counters. For your application you need decade counters, example: '160, '162, 'LS160, 'HC162. ---------- Post added at 17:38 ---------- Previous post was at 17:27 ---------- Also
Hello! Was wondering if anyone could help give an overall idea of how to implement a tach with a 16F628 in asm. As of now, I have four 7-segments hooked up and multiplexed with a TMR2 interupt to update each digit at about 6ms. (just reduced it down till it didn't flicker) I have a halleffect sensor i would like to hook up to RA4 to count wi
1) what will be the data formate of output of ADC, is it binary or bcd? It is binary 2) what should be the data output of 89c51 that is acceptable for LCD? ASCII 3) what is the acceptable data formate for LCD , binary , bcd or Ascii? ASCII The binary data in 8 bit is (...)
:-) In theory for this project you may use one IC 4 bit binary full adder and one IC quadruple 3 lines to 1 line multiplexer. The result of the multiplexer to be applied to a bcd to 7 segment decoder and address multiplexing to be implemented with push buttons. In practice we may use for example two IC dual 4-line to 1-line (...)
What do I search on Google? Dear, just use your thread title. Or "full adder".
P1. Draw the circuit diagram of a 4-bit adder which can add 4-bit binary numbers and display the result on a 7-segment display. Assume that the sum results can never exceed the number 9. Furthermore design an overflow detection circuit which will light up an l.e.d. when the sum exceeds 9. P2. Using two 74LS83A adders, modify the (...)
Say you are using 8 bits. Then a value can occupy a range from zero to 255. Say zero represents 0V, and 255 represents 5V. Then you can use a simple proportion to translate any value to a voltage. To model this in electrical terms, each analog voltage is derived by sending 5 volts through resistors of different values. Similarly each bit is weig
I am trying to set up a a 4-bit binary counter to rest at count ten. Since I didn't have LS390' I had to create a condition rest clock made from an AND gate chip. First I used one gate to get triggered when Qc and Qa where active. However when I do this it only
For an 8-bit register of PIC16F84 the data read in, is a binary number from a bcd dip switch but the bits read in are not in a uniform order (bit order is different). How to converted to a decimal value in binary format, like 54 = 00110110, but the order read in is 10110010. What is the (...)
What programming/HDL language are you using? Are those decimal numbers? If it's decimal, is it stored as binary or bcd? You may need to do integer division, like this in C: 652585432/100000

Are you really attached to the idea of doing this all via logic and counters? It's neat in a retro sense, but there are more efficient ways of doing this. Using a $.50 microcontroller and a MAX7219 (controls 64 LED's) would lower your parts count dramatically while simplifying your
The output from ADC is a binary number in the range 0 - 255 (Decimal). Convert this number to three digits (bcd), 4 bit nibbles. Use these three digits one by one, to convert it to ASCII just add 48 (decimal). Send this to the LCD display. Use appropriate order of these ASCII codes to display correct value.
