What are PIC microcontrollers used for?
At present PIC microcontrollers are extensively used for industrial purpose due to low power consumption, high performance ability and easy of availability of its supporting hardware and software tools like compilers, debuggers and simulators.
What is PIC16F877A?
PIC16F877a is a PIC Microcontroller and is normally used in Embedded Projects like Home Automation System, Bank Security System etc.
What is PIC in PIC microcontroller?
It is generally thought that PIC stands for Peripheral Interface Controller, although General Instruments’ original acronym for the initial PIC1640 and PIC1650 devices was “Programmable Interface Controller”. The acronym was quickly replaced with “Programmable Intelligent Computer”.
What is the purpose of the Eedata and the Eeadr in the reading from or writing to the EEPROM in the PIC16F84A microcontroller?
EEDATA register hold 8-bit data for read/write and EEADR holds the address of EEPROM memory location to be accessed. PIC Microcontrollers usually have 128/256 bytes of data EEPROM memory with address ranging from 00h to FFh.
Where is PIC used?
PIC microcontrollers are used in different new applications such as smartphones, audio accessories, and advanced medical devices. There are many PICs available in the market ranging from PIC16F84 to PIC16C84. These types of PICs are affordable flash PICs.
What are the advantages of PIC16F877A microcontroller?
One of the main advantages is that it can be write-erase as many times as possible because it uses FLASH memory technology. It has a total number of 40 pins and there are 33 pins for input and output. PIC16F877A is used in many pic microcontroller projects.
Which among the following is not a hardware feature of PIC?
7. Which among the following is not a hardware feature of PIC? Explanation: Some of the hardware features of the PIC microcontroller is that they have Flash memory, SRAM, EEPROM, sleep mode, watchdog timer, various crystal or RC oscillator configurations, or an external clock.
Which is the RESET pin on a PIC microcontroller?
The PIC comes with only one external reset pin which can be controlled digitally or by an external button. The reset pin is an active low pin and works on ST base logic. If you want to start with pic microcontrollers programming in c language or assembly language, you can check this complete guide:
What are the output pins on a pic16f676?
To use the external clock or oscillator with the PIC16F676 there are two pins, one for input and second for output. In this PIC there are two general-purpose I/O ports A & C, which act as output. Both the ports give the output in the TTL form. The output on these pins won’t be more than V DD.
What happens when a pin is configured to be an output pin?
If the pin is configured to be an input pin, then you’ll be reading (polling) its state several times within your program. If the pin is configured to be an output pin, then you’ll be driving its state (High / Low) within your program. 1.
How many programmable pins are in the pic18f4550?
PGD: In-Circuit Debugger and ICSP programming data pin. PIC18F4550 is easy to program PIC controller. The controller program memory satisfies most applications. Along with 35 programmable Input/output pins, it can interface many peripherals easily.
