You had not informed exactly what is the purpose of the system, whether is needed a bare detection of movement, if need to just store sampled pictures of the hall for further analysis on demand, or if need to perform image recognition and classification for counting of incoming passengers through the door, for instance. In shorts, it is your design
Hi Guys, Please correct me if I'm wrong, I tried to count the overflow for creating a delay.... Are they correct ? Thanks ledTimer EQU .100 ;100 decimal (for content of the counter to get 100ms) movf ledTimer,W ; load value to W , Status register bit Zero is altered according to value ;count for how many interrupts
Can some body plz help me to modify the following codes for counting the frequency up to 2Mhz of a square wave and sine wave: #include <16f877a.h> #use delay(clock=20M) #include #include #fuses hs,nowdt,nocpd,nolvp,noprotect #byte portc=0x07 #bit led=portc.4 void LCD_D(); unsigned int16 value; void main()
I think that is good to see just like one of examples how some Osram compact fluorescent light bulb with led works. course I give Osram as example, also there is others manufacturers with similar solutions. counting switching or s
simply make out a function and let it be called by your interrupt handler(for external interrupt) and in that function, assign your variables that are counting i.e. am,pm,hr,min,sec....etc.. to value zero..
cyanpraveen, Despite don´t know the scope in where your couter is indeed, I can point some info. Generally, in industry conveyor counter we take some cares : > Use of rottary Encoder to measure lengh of object. > Measured in pulses domain, may validate the object counting, applying width filters ( min/max size ) +++
Hi, i have a vhdl code here, I'm still missing of a certain part. How do i equate this into the code: When Q hits P, led lights up and Q stops counting. code: library ieee; use ieee.std._logic_1164.all; use ieee.numeric_std.all; entity conveyor is port ( sensor, reset : in std_logic; p : in std_logic_vector
Hi, For the running led you can use the daretodream25's suggestion and... For binary counting using only logic, you can use a "D Flip-Flop" counter. This can match your needs to know witch led is lit up and how many times the player depressed the start button. For example have a look at:
Any led will be suitable provided it Emits light you need. Preferably white color. A single 50 watt led is too available as an option. For counting the number of led's, you may Divide 40 by the current consumption of single led what you are going to use. Cheers
Many devices use combined hardware and software approach .. By software approach I mean counting steps and saving the current position in a non-volatile memory (SRAM or EEprom) .. By hardware approach I mean a sensor (e.g. small magnet attached to the shaft and hall sensor) or a micro switch .. It may work like this: in the normal operation th
hi im using PIC16C745 in assembly language with MPLAB.. I have this GSM modem which the output is connected to the PIC pin 6 (RA4) and the Modem input to PIN5 (RA3).. when the GSM modem is "ON" (connected to GND) it will turn on the led (RB7) and the RTC will start counting 1hr immediately..after the 1hr the PIC will send a signal from PIC RA3 to
I think this will work: All I have to do is come up with somekind of infrared sensor to trigger the counting. So when the bullet passes the beam it triggers the counting.:D
In my simple verilog code, I saw some warnings. I still don't know how to clear. And seg output is always at the default. I used Xilinx. Somebody can help me. My code module prj12(A, B, C, D, seg, clk, y); // Whenever B.eqn is 1 led is on and it is count // and display on 7 seg disp. counting is done between 0 and 15
