Hello. I need to use several lookup tables(DATA,DATA1..) in one program and it should change after some time(like 1s). Is it possible to do it in assembler language with 8051 microcontroler?
DATA: DB 36D
DB 1D,254D ;

I want to design a digital signal generator which can generate digital values for the Sine wave using 8051 and then convert it to analog sine wave using DAC0808. But how to compute values for a function x = sin(w n) using 8051 if i want 50 samples per cycle and 100 Hertz frequency of sine wave. I don't want to use lookup (...)

can 8051 microcontroller read in text file like notepad?
If can what should I do? I am using C programming language for microcontroller 8051

u can calculate it, i guess ur using 8-bit adc with Vref+ as 5v and Vref- as 0v
so the step size is approx 20mv,
use two ram location say voltage_msb and voltage_lsb, where the voltage is stored in milli volts in BCD format. decrement the adc reading by 1 and add 20 to it keep repeating this loop till the adc reading becomes 0.
This method is m

I am interfacing LCD module with 8051.When I am executing the program, the data I am sending is just visible in the LCD
Module and immediately everything turns complete black.When I am switching the power off the data just visibles again in the
LCd for a moment and then everythings go to blank.Can anybody help me in curing my headache.

Hi guys.. i'm planning on displaying words through two 8x8 LED Matrix using 8051 microcontroller and C programming. i would like to make the words to move as well.
My problem is for the coding part, what type of statement that i should use in writing the code? or do anyone has the related sample C language code that can share with me?

CRC calculation is required to append CRC check with below string to communicate at RS485 Link having modbus protocol.
For ex: String is 01H 03H 75H 30H 00H 12H.
Actualy i am in need to know the CRC calculation procedure to incorporate the same in 8051 coding (Assembly Language).
I have read many data on net but couldn't get

I believe Andre is referring to the generation of a lookup table of sine wave values to drive your DAC.
A table or array of the values of a sine wave is generated with a fixed time interval between sample points.
A timer and the associated interrupt service routine (ISR) can be utilized to fetch the values of the sine wave in sequential (...)

i am using 16X2 LCD with 8051 micro controller. in my c programing i declared a variable(say char a) in which the value 0xAE is stored manually(e.g. a=0xAE;) now when i want to show this value on LCD but when i send on LCD the variable name on lcd data (lcd_data(a);) then it send tha ascii value of variable a rather i want to displ
