How to create 5 second hw delay for PIC18f All About Circuits

WebMar 10, 2015 · PIC18f4550 Timer setup for 1sec Interrupt. I want to generate Interrupt (on PIC18f4550 using TIMER0) every 1 sec but by using the following code interrupt is generated after every 6 secs. #include #pragma config PLLDIV = 5 , CPUDIV = OSC1_PLL2 , USBDIV = 2 #pragma config FOSC = INTOSCIO_EC #pragma config FCMEN … WebTimer0 in 16-bit mode to count the pulses and display the TMR0H and TMR0L registers on PORTB and PORTD, respectively (be sure to read the low register of the timer first). Start the count at 0x0000 and stop the count at 0xFFFF+1. Use the MPLAB simulator to verify the proper operation of the program.

WebOct 29, 2013 · I am trying to create 5 sec hw delay using Timer0 for PIC18f4550 microcontroller. I am using 16 bit mode timer. My understanding is: Fosc = 48 mhz/4 = 12 mhz. using 256 prescaler, brings frequency to 12,000,000/256 = 46875. so period = 1/f = 1/ 46875 = 0.00002133. so to create 5 sec delay , frequency has to be 5 sec/ 0.00002133 = … WebFeb 18, 2024 · I cannot seem to write into TMR0H, even though bit 6 of T0CON is definitely set =0 (i.e. TMR0 is configured as a 16 bit mode). After running this code, TMR0L is indeed updated to 10, but TMR0H and the variable TEST_TMR0H both return a value of 0x00, even though I expect it should be =10. Any help would be appreciated. WebMar 11, 2024 · the ASM shows CLRF TMR0H and CLRF TMR0L. Now according to the datasheet there is something strange about these registers the gist being that you are not actually writing to the registers but to a buffer (which is supposed to update the registers after a TMR0L write). Any help would be appreciated. stretches for obese people
