chipKIT Project 3: Easy Pulse Meter

This is a third project in our chipKIT tutorial series and today we are going to construct a simple pulse rate meter using our Easy Pulse sensor with Digilent’s chipKIT Uno32 board. Digilent’s chipKIT Basic I/O shield is also used in this project for displaying the pulse waveform and the pulse rate. What do we need? In order […]

In-depth: TensorFlow Lite for Microcontrollers – Part 2

This blog details the inner workings of TensorFlow Lite for Microcontrollers and the role of Flatbuffers in them. Story of TensorFlow Lite for Microcontrollers Part 2/2: This blog extends my TensorFlow Lite for Microcontrollers tutorial. I was selected in Google Summer of Code, under TensorFlow, to work on building demos for TinyML and when I read through the […]

chipKIT Tutorial 6: Inter-Integrated Circuit (I2C) communication

I2C or IIC (Inter-Integrated Circuit) is a simple bidirectional serial interface, which requires only 2 signal lines for data transfer. It was originally developed by Philips in 1980′s to provide easy on-board communications between a CPU and various peripheral chips in a TV set. Today, it is widely used in varieties of embedded systems to […]

chipKIT Tutorial 5: Pulse width modulation (PWM)

Pulse width modulation (PWM) is a technique of controlling the amount of power delivered to an electronic load using an on-off digital signal. The key idea behind this technique is that the average DC value of the digital signal, and hence the power delivered to the load, can be varied by varying the duty cycle […]

chipKIT Project 2: Temperature and relative humidity logger

This project is about building a PC-based temperature and relative humidity logger using the chipKIT Uno32 board and the DHT11 sensor. The project setup requires no additional wires (other than the USB cable) and components; the DHT11 sensor is directly plugged into four I/O pins of the Uno32 board and the project is ready to […]

chipKIT Project 1: Digital thermometer using an LM34 sensor

In Tutorial 3, we learnt how to use chiKIT ADC channels to read an external analog voltage and convert it into a digital number. We also discussed about interfacing a standard Hitachi 44780-based character LCD to the chipKIT Uno32 board in Tutorial 4. Now it’s time to implement the knowledge we have gained so far […]

chipKIT Tutorial 4: Interfacing a character LCD

Liquid Crystal Displays(LCDs ) are a very popular output device for displaying graphical and alphanumeric data in microcontroller based systems. They can also provide an interactive input interface to the users. The most common type of LCD controller used by hobbyists is the Hitachi 44780, which provides a relatively simple interface between a processor and […]

chipKIT Uno32 board sends ADC output to PC through serial interface

chipKIT Tutorial 3: Analog-to-digital conversion

  Theory Many embedded applications deal with physical variables such as motion, temperature, pressure, relative humidity, light intensity, and sound. A microcontroller cannot directly handle these entities because i) they are non-electrical signals, and, ii) they are analog quantities, which means they have a continuous set of values over a given range, in contrast to […]

Pinguino Project A PIC Microcontroller Based Arduino e1681100158848

Pinguino Project: A PIC Microcontroller Based Arduino

This is a complete tutorial to make a PIC Microcontroller based Arduino. This is a complete tutorial to make PIC microcontroller based Arduino, which can run Arduino programs on PIC18F4550 or PIC18F2550 microcontroller, one advantage on this microcontroller is that it doesn’t require any external programmers, since it has inbuilt USB support. So guys, let’s get started! Step 1: Things […]
