What is PIC18F4550 microcontroller?
PIC18F4550 is an 8-bit microcontroller manufactured by Microchip with nano-Watt technology with enhanced flash, USB, and high-performance.
How many ports are available for PIC18F4550?
40 pins of PIC18F4550 are divided into 5 ports. Out of which, 35 pins are Input-Output pins which can be configured for general Input or Output by setting registers associated with them.
What is lat in microcontroller?
LAT stands for Port Latch. As in 16F, 18F also uses TRIS register to control direction of each IO pin. LAT register is used to write Output and PORT register is used read Inputs.
How many built in timers are available in PIC18F4550 microcontroller?
four Timers
PIC18F4550 is equipped with four Timers namely, Timer0, Timer1, Timer2 and Timer3.
What is Trisb in pic?
pityukecske. TRISB sets port direction, PORTB is usually used to read/write the port pin values, and there is LATB in some cases, that is used to set the pins to the wanted value.
What is the difference between LAT and port?
The differences between the PORT and LAT registers can be summarized as follows: A write to the PORTx register writes the data value to the port latch. A write to the LATx register writes the data value to the port latch. A read of the PORTx register reads the data value on the I/O pin.
What is the resolution of ADC used in PIC18F4550?
10 bits
ADC in PIC Microcontroller (PIC18F4550) The ADC in PIC18F4550 is a successive approximation ADC with a resolution of 10 bits. The resolution indicates how much the reference voltage can be divided. For a 10 bit resolution ADC, it is possible to divide up to 1024 (2^10) voltages.
Which are the 16 bit timers of pic18f458?
T08BIT and TMR0ON are the bits which are used to determine bit mode of the timer(8 or 16) and to on/off the timer respectively. # Normally we feed the ADCON register with 00001000(08H). It bypasses prescaler frequency i.e. input frequency=OSC/4, use 16 bit mode and sets the timer for internal clock input.
