Adafruit has a very good explanation about GPS interfacing. You may follow that tutorial or continue here. To view, the available USB to TTL converter devices use the following command ls /dev/ttyUSB* If you had installed pyserial then you may list all your available COM ports using this command via python python -m serial.tools.list_ports
We had mentioned using Raspberry PI GPIO as output in our previous post. Today we will talk about using Raspberry PI GPIO as input. We will try to read input from pushbuttons. We had connected pushbuttons as the Active Low state. Mean the pushbutton will remain in the Active High state unless we press any […]
After successfully installing raspbian into Raspberry PI, the first thing which comes into the mind of the embedded developer is to play with Raspberry PI GPIO. Because the very best advantage of this cheap computer is to use with external hardware through its GPIO. We are going to explain how to play with Rasberry PI GPIO’s […]
Timer0 of pic16f is popular and very basic for creating short delays or… for creating small timing pulses. It is an 8bit timer with high priority interrupt. Which makes it perfect for creating time-critical applications like frequency counter, some industrial timing control system or any medical or industrial grade application.
Accuracy is very important in Real-time applications. Especially with time-critical applications. so whenever we need something time critical we always need accurate timings. In such cases, we cannot rely on nop instructions based delays. We need something more powerful and more accurate. To handle this kind of errors we always use hardware-based timers. luckily Microchip pic […]
Abstract Food identification could be done in many ways as Every food is different in many ways, like shape, color, size and taste as well as many other chemical and electrical properties. What if we build some cool project out of it? Electronics is a fun to play with. So we are going to make […]
Introduction: The “OOK modulation” or On Off Keying Modulation is very popular now days due to VLC or Visible Light Communication. OOK modulation is easy to use and easy to implement. As we can even implement this modulation using simple 555 timer IC. In this post we are going to explain How to implement OOK […]
Introduction It is very common problem to detect when an analog signal changes its value from positive to negative or vice versa. Zero cross detector is used to solve this kind of problems. Zero cross detector is Kind of Voltage comparators used to detect the change in waveform. Zero crossing is the cross of the […]
We are going to create a LED Blink Program for stm32f103 microcontroller which comes with stm32 Bluepill development board which is cheap and handy to use. stm32 led blink program will help you to understand the basics of GPIO’s of STM32 platform and help you to understand some basics of using these GPIO as Output.
If you are familiar with some higher level language like C/C++, C#, Java or any other language you may already be well aware of if else statements. But if you are new to programming then lets just first understand what these statements are all about? and later know how to make it, and if else […]
