Introduction: In this blog post we will discuss how to interface an external I2C analog to digital converted to Raspberry pi. This procedure is applicable for pi zero, Pi3b etc… Interfacing any sensor which gives analog voltage output with Raspberry Pi requires external ADC (analog to digital converter) as BCM SOC used for RPi doesn’t […]
Raspberry Pi running without connecting display(monitor), keyboard/mouse (USB) and accessing it through SSH or serial console is called headless configuration. We have blog post https://c2plabs.com/blog/2019/04/23/enable-serial-console-on-raspberry-pi-zero-w/ which explains how to enable serial console( UART console) on Raspberry Pi. When Linux OS booting is complete you can login to shell to give commands. During initial boot configure […]
In this article, we look at using TB6612FNG motor controller, and the gpiozero python library for controlling DC motor. TB6612FNG motor driver has widely used for applications where better efficiency and performance is required. Below schematic shows the Raspberry PI zero GPIO connections to the motor controller. TB6612 motor controller can driver two motors simultaneously, […]
DS18b20 is a simple temperature sensor which gives digital output on single I/O pin based on 1-wire protocol, so this can be used with the Raspberry-Pi without the need of Analog to Digital Converter (ADC). On Raspberry Pi, 1-wire interface can be enabled by using sudo raspi-config utility, select “Advanced Option” and enable the 1-Wire […]
1. Introduction When we start working Embedded Linux SBC (single board computer) like Beaglebone black, Intel Edison, Raspberry-Pi, etc.. the important thing embedded developers look at is how easily we can do customize the kernel for these board. How easy we can configure the Linux kernel and build for that board. This also helps in setup […]
After successfully enabling serial console on “Raspberry Pi zero w” as described in the blog https://c2plabs.com/2019/04/23/enable-serial-console-on-raspberry-pi-zero-w/ In this post, we will focus on configuring wifi network using “raspi-config” and connecting to wifi network. This allows us to do ssh to Raspberry Pi and transfer files using scp from the host computer. Run the rasp-config command […]
The serial console plays a very important role in the development of system software and applications on Embedded Linux boards. Enabling serial console gives lot of advantage while using Raspberry Pi. Even though Raspberry Pi support HDMI Display interface, enabling the serial console will help in getting Linux boot logs as well as to enter […]
