<center><h1>50hz signal generator using timers</h1></center>
<p>stm32 is an ARM based 32 bit family of microcontrollers.
it offers very high performance,real time capabilities,
digital signal processing low power/low voltage operation and connectivity while maintaining full integration and ease of development.
in the above example a timer is used to generate a pwm signal of 50hz with a duty cycle of 50%.
This is suitable for controlling a servo motor .

</video></center>
<p>LCD modules require 4 data pins,three control pins when used in 4 bit mode.
In order to save a few GPIO pins we can use a 12c adapter.12c only requires 2 pins SDA and SCL.</p>

<p>freertos is an operating system that enables two or more tasks to run at the same time.
For example in the above video one LED blinks with a delay of three seconds and another blinks with a delay of one second.
