The flexio_uart_interrupt_ring_buffer example shows how to use flexio uart driver in interrupt way withRX ring buffer enabled:In this example, a flexio simulated uart connect to PC through USB-Serial, the board willsend back all characters that PC send to the board.Note: The example echo every 8 characters, so input 8 characters every time.

The flexio_uart_interrupt example shows how to use flexio uart driver in interrupt way:In this example, a flexio simulated uart connect to PC through USB-Serial, the board will send back all charactersthat PC send to the board. Note: two queued transfer in this example, so please input even number characters.

The flexio_uart_polling example shows how to use flexio uart driver in polling way:In this example, a flexio simulated uart connect to PC through USB-Serial, the board will send backall characters that PC send to the board.

The FTM project is a demonstration program of generating a combined PWM signal by the SDK FTM driver. It sets up the FTMhardware block to output PWM signals on two TPM channels. The example also shows the complementary mode of operationand deadtime insertion.On boards that have 2 LEDs connected to the FTM pins, the user will see a change in LED brightness.And if the board do not support LEDs to show, the outputs can be observed by oscilloscope.

The FTM project is a demonstration program of the SDK FTM driver's dual-edge capture feature.This feature is available only on certain SoC's.The example sets up a FTM channel-pair for dual-edge capture. Once the input signal is received,this example will print the capture values and period of the input signal on the terminal window.

The FTM project is a demonstration program of the SDK FTM driver's output compare feature.It sets up one FTM channel to toggle the output when a match occurs with the channel value. The usershould probe the FTM output with a oscilloscope to see the signal toggling.

The FTM pwm two channel Example project is a demonstration program that uses the KSDK software to generate a square pulse PWM on 2 channel to control the LED brightness.- FTM generates a PWM with the increasing and decreasing duty cycle.- LED brightness is increasing and then dimming. This is a continuous process.

This demo describes the usage of Quad Decoder feature in FTM module, which can be used to count the position of decoder.An external decoder is used to generate the PHA and PHB's signal. These two signals are feed to the FTM pins with Quad Decoder feature (FTMx_QD_PHA and FTMx_QD_PHB). Then, the counter value and direction would be displayed in terminal window predically.
