emios_center_aligned_pwm#
Overview#
The eMIOS project is a simple demonstration example of the SDK eMIOS driver to use eMIOS as PWM generator.
It configures eMIOS UC (Unified channel) as Center Aligned Output PWM with Dead Time Insertion Buffered (OPWMCB) mode.
This example generates three 10kHz center aligned PWM, there duty cycle are 50%, 25% and 12.5%.
Supported Boards#
FRDM-MCXE31B
Hardware requirements
Micro USB cable
FRDM-MCXE31B Board
Personal Computer
Oscilloscope
Board settings
Probe the PWM signal using an oscilloscope
At J3-15 for PWM channel 0
At J3-13 for PWM channel 1
At J3-11 for PWM channel 2
Prepare the Demo
Connect a type-c USB cable between the host PC and the MCU-Link USB port (J13) on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
When the example runs successfully, following information can be seen on the OpenSDA terminal:
