    PWM is a great way to control brightness of LEDs, speed of motors, etc. Most microcontrollers including STM8S has built in ability to generate PWM signals. In this article I share simple code to generate PWM signal in STM8S microcontroller. However, I don’t write anything about PWM theory other than basic calculation to get required…

    Recently I was creating a configurable timer circuit based Arduino Pro Mini. The circuit has a momentary push button which user can press to turn ON the device. The device will turn OFF itself once the time is elapsed. On starting, Arduino has to turn on a relay to get permanent connection to power source,…

    In previous post I showed how we can use Timer 2 as simple counter. In this post I am going to show how we can program to have interrupt when its value overflow. As simple experiment, we will toggle an LED in each second within the interrupt handler (also called ISR, Interrupt Service Routine).

    Timers inside MCUs are very useful and essential peripherals for timing applications. In this article I will show Timer 2 in an STM8S (specifically STM8S103F3) can be used to blink an LED.

    I successfully programmed development board having STM8S103F3P6. It is quite simple to make it blink LED. For me, it was second easiest after Arduino Uno to get started. I used SDCC as the C compiler, ST-Link v2 clone as programmer, and stm8flash to flash the binary file through ST-Link.

    In this post I will detail out how we can program an AVR microcontroller, specifically ATTiny13a, with USBTinyISP and Eclipse IDE in Linux environment. I am using Ubuntu 16.04 LTS. I hope it will work in other distributions with little or no modifications.

    Recently I brought TP-Link TL-WN823N wireless USB adapter to connect my Raspberry Pi over wireless network. Mine is Raspberry Pi 2 Model B, so not having built in wireless capability. I chose TP-Link TL-WN823N over Edimax EW-7811Un because of its 300 Mbps speed, both were available on amazon.in with similar price. It did not get…

    Sometimes I require to copy entire CD or DVD to a file in my computer in ISO[^1] format. Usually to keep it for frequent access. It is what I do normally with tutorial discs received with some products, discs of wedding videos that I need to return back soon. So, I can avoid keeping the…
