STM32 PWM (1) Example

The STM32 PWM_1 example program shows how to configure and use the timer TIM4 of STMicroelectronics STM32F103xx microcontroller to generate pulse-width modulation.

TIM4 is configured to tick every second. Channel 3, connected to PB8, has a duty cicle of 50% and channel 4, connected tp PB9, has a duty cicle of 25%. LEDs PB8, PB9 are lit during the channel's duty cicle.

The configuration of the clocks and the timer TIM4 is done using the Configuration Wizard in file STM32_Init.c.

Two µVision targets are available:

• Simulator where the program runs in the software simulator.

• MCBSTM32 where the program runs from internal Flash located on the microcontroller.

The example is tesed with the Keil Evaluation Board MCBSTM32.
