I think his requirement is if button is pressed it should increment from 0 to 99 and stop and if button 2 is pressed it should reset and become 0. I belive you are right, just my ignorance. Reviewing the first post, the code is missing keypress (edge) detection. This is accomplished by a combination of debounce, as with delay_ms(50)
Ok I know this might sound stupid and maybe easy, but I want to make a module in verilog that each time I press button and release once, the output will be either binary: 00,01,10,11,00,01...etc. Basically I want to make count up once each time I press the button. When I attempted to code it, I kept counting continuously when I press on the but
My fpga is spartan 3E-100 Cp132 (BASYS2). I have four push buttons as my inputs and I want to increment the four digits on 7-segment of the board by using them. The VHDL code is below: entity main is port(b1,b2,b3,b4 : in STD_LOGIC; clk : in STD_LOGIC; sseg : out STD_LOGIC_VECTOR(0 to 6);
Hi all this code : when i push button (high) that connected to Portb.F0 the counter will increment as follow ( 1 ,3 ,5,7,9, 11, 13, 15 ) and store these values into a vector of length 8 when Portb.f0 pushed down (low) ( the micro controller supposed to display this vector value by value each 400 ms ,But micro controller display t
Hai all, Today i was experimenting with 434MHz RF module with ATmega32. I have to send two different values to the receiver. The two different values are 1. From ADC input 2. From a variable that will increment its value when a button is pressed on switch is connected on PB2. At the receiver side i can read only one v
To control spped you have to change the delays. You have used 50 ms delay. use a variable like ms in the delay function like delay_ms(ms); and use a button to increment or decrement the value of ms on every button press. You can use ms = ms + 1; and ms = ms - 10; for increment and decrement. Use a button (...)
I need my LCD to display Queue="number" , "number" starts at 0 1) "number" count up by 1 pressing button A // (PORTAbits.RA1==0); 2) "number" count down by 1 pressing button B // (PORTCbits.RC1==0); Please help.. void lcd_init(void) { TRISD = 0x00; PORTD = 0x00; // PORTD is connected to LCD data pin LCD_EN = 0;
Hi My project is to to push button and the number should be incrementing by one every time. lets say the number is 25. When I pus button it should be 26, push again it is 27. Now how to show that on virtual terminal? Only idea that I have is standard c something like: if (button==1) num++; printf ("Number is now (...)
Hi, At the receiver side you can use a counter for which clock is supplied using a pulse generator. When ever you press the button of the TX, the pulse generator present in the RX, should generate a pulse. This will increment the count of the counter (0000,0001,0010,0100,1000, so on..) on every press of a button from the transmitter. (...)
You can use timer in mode 1 and the value in TH and TL should be loaded using some variable and this variable value will increase or decrease with action of button. and donot do increment or decrement in steps of one do it in steps of 1000-5000
I will use Timer Interrupt and counter. If counter < 3 second, increment counter. If keypad pressed, clear counter. ---------- Post added at 08:03 ---------- Previous post was at 07:58 ---------- I will use Timer Interrupt and counter. If counter < 3 second, increment counter.

increment an int in RB0 interrupt service routine. (say count++;) Then in main program introduce a code to convert the count to corresponding decimal digits and send the ascii of the digits to LCD one by one , from the MSB to LSB. Before that set the LCD cursor position. (say 0x80) Now i think you can do it...You mean you want the exact code?
Hi all, The following code is suppose to do the following but it is giving an error, please help. At start up, a string "Please Enter S-T" should show on top line of the LCD. Press and hold push button RB6 to increment the sampling time from 1 to 10 seconds shown on line 2 of the LCD. Release the pushbutton once the required sampling (...)
the process is missing n6 from the sensitivity list. But you also have problems because you have created an asynchronous counter. Because it has no time base to go from, when you press the button, it will count as fast as the propogation delay, so will increment by one every couple of nanosecons. This is the main reason it appears random when you p
For getting user values, you should have some keys(buttons). For example you can assign two buttons, one for increment and other for decrement. And another button to select the hours and minutes
You could use Timer 1 to increment a global counter via an interrupt. Pre-load timer one for a period, such as 10mS by using mplab sim, the stop watch and a breakpoint in the interrupt to check the pre-load value. You could clear the timer to start it and poll it to find the timeout period. Something like this, using mcc18 compiler.
You could pretty much do this with any programming language. Assign a different variable to each button and increment by one when the appropriate button is pressed. Do this within a loop, then constantly compare each variable with the preset codes, say 3 locations in eeprom or similar. When all three match, open the lock. You probably wont (...)
