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 […]
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.
