PIC16F877A software developer

Who is a pic16f877a software developer?

pic16f877a software developer is an engineer who works on pic microcontrollers. One of the most innovative microcontrollers available from Microchip is PIC 16F877. For its low price, a broad variety of options, good quality, and obtainability, this controller is commonly used only for advanced and modern applications. It is suitable for applications such as applications for machine control, measuring instruments, purposes of research, and so on. All the elements that modern microcontrollers typically have are featured in the PIC 16F877. The PIC16F877 chip estimate is shown below. Because of its functional versatility, availability and simplicity, it is the most widely utilized PIC Microcontroller. This PIC Microcontroller can be bought from almost any internet-based shop and you will only get this for $2-$ 3. I have a lot of offers from science students for PIC16F877a since this PIC Microcontroller uses it a lot in construction projects. So, and that is why I thought of sharing all the PIC16F877a data. If you really are unfamiliar with Microcontroller, then I would recommend that you carefully read this full post and ask your questions in responses. You can also look at this video in which I gave an explanation to PIC16F877a.

How to Pick a Microcontroller for your PIC

Microchip offers the waste truth of the PIC family of microprocessors. Each MCU does have again and downside of its own. Before choosing an MCU for your project, there are also several criteria that you have to remember. The points below are only recommendations that could support one choosing an MCU. If you are a practitioner who is studying PIC, then that will be a good option to pick an MCU that has great online support from the community and large applications. Two such MCUs are PIC16F877A & PIC18F4520. Remember the system’s voltage output. Whether they are 5V, certain sensors or systems can pick a 5V MCU and interact on 3.3V, in which situation a 3.3V MCU could be chosen. If size and cost are a constraint, tiny 8-pin MCUs such as PIC12F508 can be picked. These are generally cheaper as well. Verify which components you may need some for the MCU, focused on the sensors used during your project. For instance, you are reading several analogue voltages, then make absolutely sure there are enough ADC channels and supporting resolution for PIC. In the above table, the specifics of any and all products are specified. If your project includes wireless communication such as UART, SPI, I2C, CAN, etc., ensure that they can be enabled by your PIC. Many MCUs can accommodate and over one module of the same configuration.

PIC Microcontroller Programming

With software program available on the market, PIC microcontrollers can be programmed. There are individuals who are still programming PIC MCUs using Assembly language. The information below is for the most advanced and popular application and compiler produced by Microchip itself We will need an IDE (Integrated Development Environment), where even the development takes place, to programme the PIC microcontroller.

For your convenience, I have also supplied the connexion. Run these on your machine once they’re downloaded. If you’ve any issues doing so, you could submit them in the section below. Designers would need a system named Pick it 3 to upload or download our software into the PIC. In addition to this, other hardware such as Perf panel or breadboard, welding platform, PIC ICs, crystal actuators, battery packs, etc. will then be needed.

Memory of PIC16F877A

PIC 16F877’s basic design is focused on Harvard architecture. As noted in the earlier article, this microcontroller also has several advanced features. Here you will see PIC16F877 ‘s simple internal design and memory organisation. The storage of the software includes the programmes that the user writes. One by one, the programme counter (PC) executes these recorded commands. Typically, PIC16F877 systems have a 13-bit large programme counter capable of managing system memory of 8 K to 14-bit programmes. This memory is mainly used to store the written (burned) programmes for use by the PIC. These phones have very 8K*14 bits of electrically erasable/reprogrammable flash memory. We have to uninstall the old one at the same time any time we start a different programme on the controller. PIC16F877 ‘s data memory is divided into several banks containing high performance (GPR) and essential tactic (SPR) registers. These banks can differ depending on the type of microcontroller. There are only four banks on the PIC16F877 chip (BANK 0, BANK 1, BANK 2, and BANK4). 128 bytes of emblems are kept by each account.

Advantages of PIC16F877A

Peripheral Interface Controller (PIC) is a microchip built by a computer chip, and then when we contrast certain microcontrollers including 8051, the PIC microcontroller is quick and simple to introduce the software. Effective microcontrollers have been simple to program and easy to communicate with the other PIC peripherals.

PIC Microcontroller benefits:

They are effective and the number of PIC malfunctions is very poor. And because of the use of RISC architecture, PIC output is very fast. Compared to other microcontrollers, power design is also much lower. If we see that interoperating is very simple in the programmer’s point of view, we can also connect analogue devices directly to and use any ideas that have to involve structural. When compared with other microcontrollers, scripting is also very simple.

PIC Microcontroller Architecture:

GPR: The Processor can conveniently download the information in the registers, so multipurpose records would not have any special feature or any specific permit.

SPR: 8 bits registers have unique functions, which behave according to the provisions related to them when we use the register. Like regular registers, they cannot be used. 

ROM: The full instructions or software will be stored in the microcontroller ROM, as the programmed processor will work. In this memory user, Rom is also called programmed memory, writes the microcontroller software and indefinitely stores it and gets executed by the CPU. There are distinct types of ROM that are used in various Microcontrollers.


Flash Memory: memory chips are also a PROM in which we can read more than 10,000 times to write and delete the program. This kind of ROM is often used by PIC microcontrollers.

Stack: PIC needs to first execute the interrupt when an interrupt occurs and the current process address being performed is placed in the mound and stack.
