hi every one
i m trying to make a "Master-Mind" game with different skill levels
there are 5 levels, and one "stopwatch" to count the time; that player consume
when player select any one skill mode to start a game, the stopwatch start to count the time
the player must solve the game with in...
hi
i m using mikroC PRO for PIC
in the examples of mikroC PRO for PIC, i saw one code
ANSEL = 0; // Configure AN pins as digital
ANSELH = 0;
C1ON_bit = 0; // Disable comparators
C2ON_bit = 0;
In the example file, in the comments, ANSEL = 0; mean to Configure AN pins as...
hi
as i know that 89c51 is the most popular micro-controller, designed by ATMEL, its built in serial function is very useful, but the problem is that 89c51 didnt have a built-in I2C function, my question the that Is there any microcontroller having I2c function built in, in 80 series???
or...
i found the PDF file (Attached with this Thread), in this file; at page 1 shown that pin6 of rj45 same as pin3 of Com-port and pin3 of rj45 same as pin2 of Com-Port (RxD and Txd)
so is it possible to send serial data via Ethernet using 9600 baud rate ??????????????????
hi
i m making digital clock using 89c51, in this clock the series of LED work on 9 volt, so i used lm324 to amplify the voltage with 5 volt signal, this output is stable across direct-ground, but the second end i used A683 (PNP) transistor, for ground (-) normal its show 9 volt across 10-volt...
hi,
i m trying to control the lights, fans and other electronic devices using serial, so when i send a serial data with specific code, the specific uC read the data and turn on/off one pin, so using this pin i can turn on or off required device.
i want to know which microcoltroller is smallest...
hi
i have two variable
unsigned char x = 170; // 10101010
unsigned char y = 255; // 11111111
now i want to copy the 3rd bit of x (Bold) to the 6th bit of y (underlined)
in keil 4.10, portable using C
how can i do it?
hi
i want to read the analog signal using 89c21, and convert it to digital
e.g
if signal signal is 5v then convert it to 255 in digital form, and if signal is 2.5 volt then it will be 127
is it possible, if yes then HOW?
using software : KEIL
language : C
thnx
i m using lm324 , the frequency is almost 100 hz, and load is aprox 1.5 amp (using 12 v) simply i m using bd-135 for load, its normal power is 1.5 amp, but during switching it can work on 3.0 amp
and very important is that, both ( + ) and ( - or ground) are from micro-controller so i also need...
here i m trying to explain
and very important is that, both ( + ) and ( - or ground) are from micro-controller so i also need stable or regulated ( i m not sure which word is more usable) ground or (-)
hi
i m using 89c51 to displaying different type of bulbs, and i need a regulated output, the problem is that i m using switching mode, so how can i get a regulated output
hi
i m using 89C2051
i want to read the temperature using i2c in Keil uVision4
is there any simplest code ? // In C
i mean just send address and read data
no more
hi
I am using 89c51. for using serial port I am using these commands
SCON = 0x50; /* SCON: mode 1, 8-bit UART, enable rcvr */
TMOD = 0x20; /* TMOD: timer 1, mode 2, 8-bit reload */
TH1 = 0xfd; /* TH1: reload value for 9600 baud...
hi
i m using 89C51, the 3 ports (P1, P2, P3) are used for different purpose, but the remaining port (P0) , the Open Drain, is remain, the problem is that, I want to use it for 15 different Lights, using matrix, (3 Rows and 5 columns) the 3 rows are positive volt and 5 are minus/ground (each pin...
