LM35 sensor data to an LCD in 8-bit mode using a PIC microcontroller

 To send the LM35 sensor data to an LCD in 8-bit mode using a PIC microcontroller, you can directly access the control and data registers of the LCD (typically using the PORT registers for data and control signals). Below is a simple example code for this, assuming you're using a PIC microcontroller and the 16x2 LCD in 8-bit mode . Assumptions: LM35 sensor is connected to an analog pin (e.g., AN0 ). LCD is connected to the microcontroller's PORTD for data and PORTC for control signals. PIC16F series is being used, but it can be adapted for other PICs as well. Simple Code: #include <xc.h> #define _XTAL_FREQ 4000000 // Set your oscillator frequency (e.g., 4 MHz) // Function to initialize LCD void LCD_Init(void) { // Set LCD control pins as output TRISC = 0x00; // PORTC as output for control signals (RS, RW, EN) TRISD = 0x00; // PORTD as output for data // Send 8-bit command to LCD LCD_Command(0x38); // Function set: 8-bit, 2 lines, ...

Basic Concept of GPIO Access in PIC

 If you're asking about how to access and use ports or GPIO pins on a PIC microcontroller in the context of a blogging project , such as controlling external hardware (LEDs, sensors, etc.) through the microcontroller and sharing this with a community, here's how you could approach it: 1. Basic Concept of GPIO Access In a blogging context, you can introduce your readers to how microcontrollers like the PIC can interact with hardware, such as sensors or actuators, by accessing GPIO ports. Each port on the microcontroller corresponds to physical pins that can be set to either input or output , and you can use these pins to interact with the environment (e.g., turning on an LED or reading a temperature sensor). 2. Steps to Access GPIO Ports in a PIC Microcontroller Setting the Port Direction : Each port on a PIC microcontroller (like PORTA or PORTB) needs to be configured as input or output. This is done through the TRIS (Tri-state) register , which defines whether a pin ...

Getting Started With PIC Microcontrollers

Image
  Getting Started With PIC Microcontrollers This tutorial is designed for beginners who are new to the world of Microcontrollers, to provide a little know-how about the technology. PIC (Peripheral Interface Controller) family is popular among students, hobbyists and also industrial developers due to its low cost, serial programming capability and its ease of availability. The 8-bit PIC microcontrollers are divided into four large families based on their built-in special features: PIC10FXXX series PIC12FXXX series PIC16FXXX series PIC18FXXX series Although, Microchip also provides advances series of microcontrollers also such as PIC32, PIC24, and DSpic. But if you are a newbie in this field, we recommend you to start with PIC16 or PIC18 series. How to Start Learning Pic Microcontrollers? To dive into the learning process of Pic microcontroller, we first need to select a microcontroller.  We should always pick a simple (Low pin count and less number of peripherals) and famous mi...

PIC MICROCONTROLLER ARCHITECTURE

Image
  PIC MICROCONTROLLER ARCHITECTURE PIC MICROCONTROLLER  ARCHITECTURE:  PIC stands for Peripheral Interface Controller. PIC microcontroller was developed by microchip technology in 1993. It was developed for supporting PDP computers to control its peripheral devices and that’s why it was named Peripheral Interface Controller. PIC microcontrollers are of low cost, very fast and easy for the programming and execution of program. Their interfacing with other peripherals is also very easy. PIC Microcontrollers from Microchip Company are divided into 4 large families. In this PIC MICROCONTROLLER ARCHITECTURE article, I will explain step by step about PIC MICROCONTROLLER ARCHITECTURE and components used in pic microocntrollers. I recommend you to check a list of  Pic microcontroller project  here. First family:             PIC10 (10FXXX) called Low End Second family: PIC12 (PIC12FXXX) ...

Introduction to SPI Communication on the PIC16F877A

  Introduction to SPI Communication on the PIC16F877A SPI (Serial Peripheral Interface) is a fast and efficient synchronous communication protocol widely used in embedded systems. It allows a master device to communicate with one or more slave devices over a short distance. The master device generates the clock signal (SCK) and selects the slave to communicate with using the Slave Select (SS) pin. Data is transferred in full-duplex mode, meaning both transmission and reception occur simultaneously, making it ideal for applications like interfacing with sensors , memory chips , GPS modules , GSM modems , and more. The PIC16F877A microcontroller has a built-in SPI module, which simplifies communication with other SPI devices. In this guide, we will walk you through the basics of setting up SPI communication on the PIC16F877A in master mode . You’ll learn how to configure the necessary pins, initialize the SPI module, and send/receive data. Basic Code for SPI Communication o...

Introduction to UART Communication

1. Introduction to UART Communication What is UART? UART stands for Universal Asynchronous Receiver-Transmitter , a hardware communication protocol that allows two devices to exchange data asynchronously (without a shared clock). It uses two wires: one for transmitting data (TX) and one for receiving data (RX). Applications of UART Communication with peripherals like GPS modules , GSM modems , Bluetooth modules , and RS232 communication . 2. Understanding the PIC16F877A’s UART Module Microcontroller Overview The PIC16F877A has an integrated USART module , which allows easy communication with serial devices. The USART can operate in both synchronous and asynchronous modes, allowing flexibility for various communication requirements. Registers Involved TXSTAbits : Controls the transmission. RCSTAbits : Controls the reception. SPBRG : Baud rate generator register. PIR1bits : Interrupt flag register, for interrupt-based UART handling. 3. Baud Rate Calculat...

Understanding UART Initialization for PIC16F877A

  Understanding UART Initialization for PIC16F877A In this blog post, we will break down the UART (Universal Asynchronous Receiver Transmitter) initialization code for the PIC16F877A microcontroller. UART is a widely used protocol for serial communication, enabling devices to exchange data using just two lines: TX (Transmit) and RX (Receive) . Code Explanation void UART_Init(void) { SPBRG = 31; // Baud rate for 9600 at 20 MHz clock TXSTAbits.BRGH = 0; // Low speed TXSTAbits.SYNC = 0; // Asynchronous mode RCSTAbits.SPEN = 1; // Enable serial port TXSTAbits.TXEN = 1; // Enable transmission RCSTAbits.CREN = 1; // Enable continuous reception PIE1bits.RCIE = 0; // Disable UART RX interrupt } This code initializes the UART module of the PIC16F877A to communicate at a 9600 baud rate , which is a common speed for serial devices like GPS modules, GSM modules, or debugging terminals.
