The secret to searching the net is using a couple of words and trying to think of unique ones. E.g. in this case - hex bcd keypad. Note that "keypad" is a better word than "keyboard" in this case. Also try to exclude words that you know will trigger false hits. I use to search and it performs well for me. It's a Swedish si
Salam, You didn't mention what is the length of the hex 8 bit, 16 bits ...etc Ok here is a simple method to convert hex (8bit) to bcd One restriction that method is vaild fot numbers 0 - 99 only. for example if you want to convert 99 to bcd 1- divide 99 by 10 2- put the result in the high nibble of the (...)
can any one suggest how to write an assembly language program for 8051 to convert hex to decimal ? 8-bit hex to bcd convertor Handling of hexadecimal numbers for 8051 Assembly
anyone got a quick routine to converte hex to decimal (8 bits only) for 8051? Thanks RAF
What do you mean by "decimal number"? Is this bcd number? In example, if you have 0x12 hexadecimally you want to change it to bcd number: 0x18? 0x18 is decimal representation of 0x12 hexadecimal number. C routine for that conversion (hexadecimal must be less than 0x64): unsigned char (...)
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.. then conv
in my project i require bcd at port 0 and 3 of microcontroller 89s52 since there are three 7447 connected (i.e p0.0-p0.3 to 7447(1) lsb, p0.4-p0.7 to7447(1), p3.0-p3.3 to7447(3)msb) which drive three 7 segment displays now suppose i want to display (240)d then in the accumulator there is its hex equivalent i.e (F0)h which is proper but now w
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 (...)

please can anyone send me 8051 asm code for hex-bcd
the +-48 trick is used with numbers because it can convert a value 0-9 to a char representation 0-9 and vice versa, you are obviously trying to convert a hex value of 0-15 (0-f) to the char 0-9 and a-f and vice versa. You can use a condition that checks if the number is <=57 (which is char 9) and if true subtract the value 48 , if false then you
Hello! Preliminary: uint16 a1 = 0x1234; // a1 is an unsigned int value, not hexa uint16 a2 = 4660; // a2 is an unsigned int value, not decimal either. And a1 = a2 uint16 a3 = 0x4660; // a3 is the bcd (binary coded decimal) value of a1 or a2 char * str1 = "0x1234"; // str1 is a string, that can represent a1 or a2 in hexadecimal (...)
hi the best solution for this kind of task is 4543 from cmos line up if you give me one day and aslo be more specific what you need is just want to interface thumb wheel switch,or you have some other task as well, which kind of thumb wheel you going to use hex or bcd

Hi, I need help with this module . It's to convert a binary value to its bcd equivalent assigning each digit to an element of an array. For example the binary value (11111111=ff hex) is equivalent to( 255 ) decimal so the 5 digit is assigned to the first element of the array......second 5 is assigned to the next element and 2 is assigned to the th

Please explain more clearly what you mean by "hex" and "decimal". Do you want to convert an ASCII string such as "12FC3B" into another ASCII string "1244219"? Or something else?
I want to make an RPM meter in assambly lang. i did it as follows 1: i made 1 sec timer with T1 which does "2" step after every second. And i used T2 as event counter which is the input (P3.4) of the meter. it counts the pulses from sensor. 2:this routine saves the value of TL0 in ram then mulitplies it with 60 (3CH)to make it RPMs from RPS which
Hi, Think this site will help you do your conversions - Not sure what you are actually converting from / to - but generally it is binary / hex to a lcd decimal display - so the Ascii converters are the ones to use.
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 of a designing project and we are (...)

hi, my work is to read data from temperature sensor which is interfaced to 8051, i can read it but to display it , i need to convert hexadecimal to decimal, plz any one give some info how i can convert it and display it.
plz help me urgent how to convert decimal value to hex value in 8051 plz send me the assembly code
in 8051 series there is very easy to add 2 digits in bcd. "DA" instruction is used for this. now in AVR i want to add 10 digits with 5 digits. how that is possible in very low time, just like using DA in 8051. but unluckily there is not any instruction in AVR instruction set. please help me. i know 1 method. by using "ADC", do all in "hex" then
Hello! I need to convert decimal values 0 to 255 to hex. Can somebody please give me the c code for decimal to hex conversion?
hi i need following topics for PIC16 in assembly language. 1. 16 bit (2 bytes) Addition, Subtraction, multiplication, division 2. conversion of numbers from hex to bcd. 3. equivalent function of DAW (in pic 18) thanks in advance
Q1)which IC can be used as a bcd to hex converter? Q2)circuit diagram or methodology for interfacing 4 thumwheel switches & 4 digit 7 segment display?
2 ways to do this imo. Use common anode like sugested or use a bcd 7 segment display. The bcd saves portpins and gives you the A-F hex codes for free :-). If you have enough ports you can connect the displays to separate ports.
you dont need floating point! you just need fixed point. it is easy, convert hex value to bcd and according you circuit specification assume one or 2 digit decimal point. for example: reading 212 but print 2.12 Volt

hi friends, can someone please help me out in designing a small function in c programming to accept decimal value as hex value, i mean lets say if user inputs a decimal value say 49, the processor should read(and futher processes) it as 0x49(hex value). Thanks . With regards
Hai, I would like to convert the 16 bit hex value into 16 bit decimal value , can anyone tell me how i can do it in the C coding(keil). reply please... thanks by dayal
I think you mean a bcd-to-7-segment decoder. Here is the 'case' statement from a digital clock project that I wrote some time ago. Maybe it will help you. 'nibble' is the 4-bit input code (similar to your bcd value), and 'segment' is an 8-bit register connected to the 7-segment display (and its unused decimal point). It displays hex (...)
Hi guys, i need your help,how do i convert a hex to decimal using MPLAB assembly language? Added after 2 minutes: oh,forgot to mention. How do you convert FE to 254 with each digit in a different register?because i want to display it LCD

Packed or Unpacked bcd? The algorithm is fairly simple: The hex equivalent of ASCII '0' is 30H, Therefore to convert a packed bcd to ASCII you must first unpack it and then add 30H to the unpacked bcd Packed bcd 73H 0111 0011 Unpacked bcd 07H 03H 0000 (...)
This is the opposite prob from what most folks want. I need to convert a bcd number -- 6 digit -- into its binary/ hex equivalent. The bcd can be packed/ not packed. I prefer not-packed for now. Can someone provide pointers to an 8-bit assembly implementation for an efficient algorithm ? Its for an AVR project, using Atmega48 as of now
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
Hi, Try DM9368 or SN7448 SN7449 ! Cheers DM9368 is bcd to hex display he is asking bcd to decimal, so best is CD4543
putchar is letting out a hex value of a said string or ascii. If you want to print a number, you must use the printf command with the corresponding instructions.
1)For every key pressed once, do i have to store the decode logic in a register?like i mean if i wan't to get a numeric value "90" from the user, the two keys will be pressed once and each time i'll have to store them individually in a register. Then how do i go about decoding those two register values to get "90" as a number finally? [/qu
Jdhar is talking about HyperTerminal from Windows OS. If you send from MCU to PC 00110000 and receive this bit stream in HyperTerminal you'll see on the screen 0 (as converted to ASCII). But if you use a program made by you, can display as convenient (hex, bcd, binary, ASCII).
I don't think it's possible to shift an integer number in this way.... should be in hex format... for example,,, if you have this number 23 = 00010111 .... there is no way that you can shift this number to get just the 2, or 3 and leave the other. You should work in hex or any bit vector format, to see clearly which bits you want to shift. In you

How do you want to control this circuit? The above design uses 16 values (0-15) on 4 pins for frequency control. Basically, you could use 4 switches to get the 16 different values. That seems a bit clumsy to me, though. There are bcd and hex rotary switches that encode on 4 output pins (+gnd) that would work. Pull the outputs high. H
I think that the best solution was given by another posts and is the multiplexing. It turns the circuit more simplest and use less lines. You can group the led and the activate by an transistor for example if the mux frequancy is high you will not notest the blink. using the cpld to drive your led is an problem becouse with 5 led or 10 led is po
