 # A short guide to choosing PWM pins for your application

+When choosing pins for your application, there are a few things to consider. The most important thing is to make sure that the pins you choose are compatible with the hardware you are using.
 Make sure to check that your microcontroller family and SimpleFOC supports the necessary PWM generation, position sensor and current sensing technique. You can find this info in our docs [here](microcontrollers).

+After choosing an appropriate microcontroller, it is time to consider which pins to use. There are three main questions:
 1. Which pins to use for PWM generation?
 2. Which pins to use for the position sensor?
 3. Which pins to use for current sensing?

+In this guide, we will focus on the first question: **Which pins to use for PWM generation?**
 
 The answer to these questions depends on the microcontroller you are using and the hardware you have.  Here is the list of microcontroller families supported by SimpleFOC and the PWM generation modes supported by each of them:

-What is important to see is that all the supported families can be used with 2/3/4PWM modes. However, not all the architectures support 6PWM mode. Additionally, the PWM frequency can be configured for all the supported architectures, but for Arduino AVR boards, the frequency can be set to either 4kHz or 32kHz.

-Another important factor when it comes to choosing the PWM pins is to try to use the PWM pins that belong to the same timer. This is important because the PWM signals generated by the pins that belong to the same timer will have the same frequency and phase. This is important for the FOC algorithm to work properly.

 The rule of thumb:
 - For 2PWM mode, try using only one timer.
 - For 3PWM mode, try using only one timer.
-- For 4PWM mode, try using only one timer if possible, if not use one timer per phase (so two timers).
-- For 6PWM mode, try using only one timer if possible, if not use one timer per phase (so three timers).

 When it comes to 6PWM mode, the user has two choices:
 1. Use the pins that belong to the same timer.

 Once you provide the SimpleFOC driver object with a set of pins, the library will automatically associate the pins with the appropriate timers and channels and find the best combination for motor control. If the pins are not compatible with the motor control mode you are trying to use, the library will throw as error.
