Interfacing 'Sensor Name' with 'Board Name' using Shunyainterfaces

Add the image of the board or the your group working on shunya interfaces

Introduction

We are going to interface an ADXL335 (accelerometer) sensor on Raspberry Pi 4 with Shunya O/S

Add the description of your project and is applications

Materials required :

• Raspberry Pi 4B
• Raspberry Pi 4B compliant power supply
• 8GB or bigger micro SD card

Connections :

Add a photo of your fully connected circuit.

• connection between raspberrypi and pcf8591

PCF8591	-	Raspberry Pi 4
SDA	<---->	Pin 3
SCL	<---->	Pin 5
VCC	<---->	Vcc
GND	<----->	GND

• connection between pcf8591 and ADXL355

PCF8591	-	ADXL355
Ain1	<---->	X
Ain2	<---->	Y
Ain3	<---->	Z

you can create tables using this syntax

Procedure

Step 1: Install Shunya os on Raspberry pi 4

1. Download Shunya OS from the official release site
2. Shunya OS guys have a decent tutorial on Flashing Shunya OS on Raspberry Pi 4.
3. Insert micro SD card into Raspberry Pi 4

Step 2: Install Shunya Interfaces

1. Connect to the wifi using the command

    $ nmtui

2. Installing the Shunya Interfaces is easy, just run the command

 $ sudo apt install shunya-interfaces

Add more Steps as per the project

Code :

#include<stdio.h>
#include<stdlib.h>

#include<shunyaInterfaces.h>
#include<pcf8591.h>


void main(){
        int x,y,z;
        /*Initialize Shunya Interfaces library*/
        shunyaInterfacesSetup();
        pcf8591Setup();
        while (1)
        {
                x = pcf8591Read(A1);
                y = pcf8591Read(A2);
                z = pcf8591Read(A3);
                /* Reading converted value at pins of ADC whose addresses 
                 * are given by 0x01, 0x10, 0x11
                 */
                printf("X pin : %d\n",x); 
                delay(100);
                printf("Y pin : %d\n",y); 
                delay(100);
                printf("Z pin : %d\n",z);
                delay(1000);
        }
}
